Abstract A revised classification and checklistof New Zealand pteridophytes is presented, basedon recently published phyletic schemes for thePteridophyta, and on revisions of individualfamilies and genera. The list comprises 211 speciesof which 22 are adventive and 189 native; the latterinclude 8 unnamed species (either undescribed orunidentified) and a further 6 which are subdividedinto separate subspecies. Of the native taxa, 89 spe-cies (47%) and 3 subspecies (50%) are believed tobe endemic to the New Zealand botanical region.Individual taxa are discussed with particular refer-ence to recent revisions and areas requiring furtherstudy. Synonymic and alphabetical lists are pro-vided of all validly published pteridophyte namesbased on New Zealand types or used by authorswith reference to the New Zealand flora. The moreimportant species erroneously or dubiouslyrecorded for New Zealand are also listed.

INTRODUCTION
The currently accepted standard reference work onthe New Zealand pteridophytes is still the treat-ment by Allan (1961) in Volume I of the "Flora ofNew Zealand". This has since been supplementedby two well-illustrated and widely-read publica-tions (Crookes 1963, Heath & Chinnock 1974), but
Received 5 October 1984; accepted 29 January 1985
regrettably neither of them is comprehensive in itscoverage, the former dealing only with the Filicop-sida and the latter omitting many of the rarer andSouth Island species.
Allan's work on the pteridophytes, though notpublished until 1961, was actually completed manyyears previously and was based on the classifica-tion proposed by Holttum (1949). Holttum himself(1973a) has now revised many of his earlier ideaswhilst in recent years several other workers (Nayar1970, Crabbe et al. 1975, Lovis 1977, Pichi Ser-molli 1977) have also produced phyletic schemesof their own which depart radically from tradi-tional ideas of fern evolution. In the light of thesechanging concepts of fern classification it is clearlydesirable that some attempt be made to provide amore modern arrangement for the New Zealandpteridophyte flora.
Our concepts of families and genera are alsochanging and in the twenty or more years sinceAllan's work there have been major revisions ofsuch families as Hymenophyllaceae (Morton 1968),Cyatheaceae (Tryon 1970), and Thelypteridaceae(Holttum 1971) as well as generic revisions of Las-treopsis (Tindale 1965), Doodia (Partis 1972), Tme-sipteris (Chinnock 1975), Grammitis (Parris &Given 1976), Lindsaea (Kramer & Tindale 1976),Asplenium (Brownsey 1977a, b), Deparia (Kato1984), and Hypolepis (Brownsey & Chinnock 1984).These, together with other smaller revisions, addi-tions of new species, and sundry nomenclaturalchanges, have resulted in a situation where a highproportion of the names used by Allan (1961) areout of date.
In recent years, too, New Zealand botanists havebecome increasingly aware of the importance ofadventive species. Though the number of intro-duced pteridophytes is small, there are some whichare of significant distribution or economic impor-tance. None are included in Allan's Flora, whereonly the native species are dealt with, but they haverecently been listed by Brownsey (1980).
No comprehensive study of the New Zealandpteridophyte flora similar to those produced byBrownlie (1969, 1977) for New Caledonia and Fijihas yet been attempted, and over two decades haveelapsed since the publication of Volume 1 of Allan'sFlora. The purpose of the present publication istherefore to provide an interim review of theincreased knowledge of New Zealand pteridophyte

taxonomy and to suggest areas where further workis desirable. Specifically this includes:i) A revised classification and checklist of NewZealand pteridophytes based on other recentlypublished phyletic schemes for the Pteridophyta.ii) Comment on individual taxa with particularreference to recent revisions and areas requiringfurther study.iii) A synonymic list of all the published pterido-phyte names either based on New Zealand materialor used by authors with reference to the NewZealand flora.iv) A list of the more important species erro-neously or dubiously recorded for New Zealand.
CLASSIFICATION OF THE NEW ZEALANDPTERIDOPHYTA
In the last 15 years, at least five phylogenetic class-ifications of the Pteridophyta or Filicopsida havebeen proposed (Nayar 1970, Crabbe et al. 1975,Lovis 1977, Pichi Sermolli 1977, Tryon & Tryon1982). Despite many differences in the detailedarrangements of families and genera in theseschemes and in the levels of the hierarchical groupsadopted, there are some encouraging signs of broadagreement. Within the more advanced ferns, forexample, the classification of which has alwaysproved the most contentious, three major lines ofevolution have been recognised in all but the lastof the proposed schemes:
i) Schizaeoid ferns leading to the adiantoid ferns,ii) Gleichenioid ferns leading to the dipteroid,polypodioid, and grammitioid groups,iii) Cyatheoid, thelypteroid, and dennstaedtioidferns leading to the asplenioid, dryopteroid, dav-allioid, and blechnoid groups.
However, Jarrett (1980) has recently criticised theassociation of the Polypodiaceae and Grammiti-daceae with the gleichenioid ferns, and believes thatthey are allied to advanced indusiate families (seep. 439). Her ideas on the relationships of the poly-podioid ferns are reflected in the essentially con-servative scheme of Tryon & Tryon.
Placement of the filmy ferns and their satellitegroups remains the major area of disagreementbetween the other four schemes, Nayar and PichiSermolli including them in the cyatheoid line, whilstCrabbe et al. and Lovis retain them as a quiteseparate group. Of lesser concern are the Marsi-leales which are placed as an off-shoot of the schi-zaeoid line by Lovis and Pichi Sermolli but leftundecided by Crabbe et al. and ignored by Nayar.
Only Crabbe et al. and Pichi Sermolli havetreated the fern allies in detail but there appears to
be no major disagreement between them — neitherauthor choosing to include the Psilotales within theFilicopsida as suggested by Bierhorst (1971, 1977).Pichi Sermolli has, however, rearranged the fernallies, moving the Psilotopsid line closer to the trueferns.
The classification outlined here owes somethingto all the recently proposed schemes but is iden-tical to none of them. It is probably closest in over-all concept to that of Pichi Sermolli, but differs inthe transposition of the schizaeoid and gleichenioidlines, and most significantly in the hierarchicallevels adopted for different taxa. Pichi Sermolli ismore divisive in his taxonomic approach than us,with the result that his subclasses correspond toour orders, and his orders approximate to ourfamilies. In the circumscription of families (thoughnot in systematic arrangement) our scheme is iden-tical with that of Tryon & Tryon (1982) except forthe Grammitidaceae which they include withPolypodiaceae.
No consideration has been given to subclasses orsubfamilies in this classification, the purpose beingsimply to provide a more modern arrangement ofthe New Zealand taxa rather than a complete phy-logenetic break-down. The latter can only beachieved by consideration of all the known ferntaxa and is outside the scope of the present paper.Genera and species are arranged alphabeticallywithin families.
The list of species accepted here and the choiceof names for them are in some instances purely amatter of personal opinion based on availableknowledge at this time. Some compromise has beennecessary, even between the three authors of thispaper — the question of Cyathea versus Alsophilaand Sphaeropteris being perhaps the best example.It is hoped, however, that the list will provide areference point for future work on the New Zealandflora, and that the accompanying notes will indi-cate where the Rules of Nomenclature dictate theadoption of a particular name, or alternativelywhere a valid choice exists.

Table 1 Numbers of native and adventive fern speciesin New Zealand.
The numbers of native and adventive species inNew Zealand are given in Table 1.
PsilotaceaeAs discussed in detail elsewhere (Brownsey & Lovis,in prep.), we believe that the balance of morphol-ogical, cytological, and chemotaxonomic evidencedoes not support Bierhorst's (1971, 1977), proposalto include the Psilotaceae within the Filicopsida.Nor does the cytological evidence lend support toPichi Sermolli's (1977) recognition of two families— Psilotaceae and Tmesipteridaceae. Our treat-ment of the Psilotaceae with two genera, Psilotumand Tmesipteris, is therefore essentiallyconservative.
Chinnock (1975, 1976) recognised four species ofTmesipteris in New Zealand which are acceptedhere. However, his two subspecies of T. elongataare less easily justified.
Lycopodiaceae
A conservative treatment of the Lycopodiaceae hasbeen adopted here. The family is in urgent need ofa comprehensive revision, both on a world-widebasis and within New Zealand. The distinctionbetween Lycopodium and Phylloglossum is univer-sally accepted but many authors subdivide Lyco-podium further, Crabbe et al. (1975) accepting fourgenera, Pichi Sermolli (1977) six, and others stillmore. Until the classification of the Lycopodiaceaeis more satisfactorily resolved we prefer to retainthe umbrella genus Lycopodium with a number ofsubgeneric segregates (as proposed, for example, byWilce 1972), especially as the adoption of somesmaller genera would require new combinationswhich in the present state of uncertainty is clearlyundesirable. Recent phytochemical work by Mark-ham et al. (1983) supports the division of the genusinto at least three groups and emphasises the dis-tinctive nature of L. cernuum and L. scariosum,suggesting that chemotaxonomy may prove a valu-able tool in subdividing the family.
436 New Zealand Journal of Botany, 1985, Vol. 23
Within the New Zealand flora, L. billardieri, L.novae-zelandicum and L. varium, previously con-sidered distinct, are here reduced to forms of onepolymorphic species under the latter name. Fur-ther work is required on this aggregate, includingthe possibility that Forster's L. myrtifolium (whosetype has not been located) is an earlier name forthe species. The relationships between L. fastigia-tum and L. magellanicum, particularly in suban-tarctic regions, and between L. laterale, L. diffusumand L. ramulosum in Australia and New Zealandare also in need of study.
SelaginellaceaeThree adventive species of Selaginella are presentin New Zealand. One of them, S. moellendorffii, isoften cultivated in glasshouses and is occasionallyfound naturalised in the Auckland area. Another,S. kraussiana, is now widely distributed and is apotentially troublesome weed. The third species, asyet unidentified, has recently been collected fromWhangarei Falls.
IsoetaceaeThe two traditionally accepted species of Isoetes,I. alpinus, and /. kirkii, are retained here but recentwork by Marsden & Chinnock (in prep.) suggeststhat they may be better regarded as varieties of /.kirkii.
EquisetaceaeOne aggressive adventive species, Equisetumarvense, has been recorded in several parts of thecountry since 1920 and appears to be spreading(Brownsey et al. 1985).
OphioglossaceaeThe results of an investigation of Botrychium inNew Zealand have recently been reported by Brag-gins (1980). On the basis of such characters as fronddissection, presence or absence of contractile roots,colour forms of the frond, and ecological require-ments, Braggins concluded that the two tradition-ally recognised varieties of B. australe are betterregarded as distinct species, and these are acceptedhere. The third species, B. lunaria, which had pre-viously been collected only once in New Zealandfrom Mt Torlesse by J. D. Enys in 1882, has recentlybeen found again (Druce 1984), almost 100 yearslater in two sites in N.W. Nelson — Billies Knobin the Owen Range (CHR 389685), and on thesummit of Mt Hoary Head (CHR 366084). Whetherit occurs in other alpine localities of the SouthIsland remains to be determined.
Ophioglossum is a taxonomically difficult genus
in which satisfactory characters are largely absentand species limits more than usually open to dif-ferent interpretation by different workers (exem-plified by the contrasting approaches of Clausen1938b and Wieffering 1964). New Zealand materialhas not been adequately studied and needs carefulcomparison with overseas types.
Clausen (1938a,b) carried out a worldwidemonograph of the genus and cleared up somenomenclatural confusion which had previouslyclouded the taxonomic problem. He showed thatO. pedunculosum as originally described by Des-vaux (1811) was a species with a distribution rang-ing through Africa, India, and Indonesia. Later,Pichi Sermolli (1954) pointed out that it was syn-onymous with O. costatum described by RobertBrown (1810) from Australia, but, although PichiSermolli included "...? New Zealand" in its distri-bution, O. costatum is not known to occur here.Unfortunately the situation has become confusedbecause Prantl (1884) later used the name O.pedunculosum in a quite different sense to Desvauxfor the plant now known as O. petiolatum Hook,which has a much wider distribution in Central andSouth America, Africa, India, Japan, China, S.E.Asia, New Guinea, New Zealand, and the PacificIslands. Unfortunately Prantl's misinterpretationof O. pedunculosum has been followed by manysubsequent authors, including Dobbie (1951), Allan(1961), and Crookes (1963) who were evidentlyunaware of Clausen's work. Subsequently Wieffer-ing (1964) has reduced O. petiolatum to synonymyin O. reticulatum L., two species which Clausen(1938b) had kept separate, whilst conceding thatthey tended to intergrade. On the other hand, Wief-fering's O. reticulatum is, by his own admission,"highly polymorphous" with chromosome num-bers ranging from n=120 to c.630. Hence, until suchtime as a more satisfactory basis for defining spe-cies of Ophioglossum is found, we prefer to followthe precedents established by Brownlie (1969, 1977)in his Floras of New Caledonia and Fiji, and usethe name O. petiolatum for a plant which is nowvery rare in New Zealand (Brownsey 1985).
The smaller and more common New Zealandspecies was first described as O. coriaceum by Cun-ningham (1837). However, Clausen (1938b) reducedSouth American, Australian, and New Zealandmaterial to subsp. coriaceum of the European O.lusitanicum. This treatment was accepted in Aus-tralia by Smith (1966) and Tindale (1972) but morerecently Chinnock (1978) has included all Austral-ian and New Zealand material within O. lusitani-cum. Cytological investigation of several NewZealand populations, including some dwarfedcoastal forms, has shown that n=120 (Brownseyunpub.) suggesting that there is indeed some cor-respondence between New Zealand plants and

European material of O. lusitanicum for whichManton (1950) reported n=c.l25-13O. However,Ninan (1956, 1958) reported n=240 in Indian plantsof this species and Verma (1957) n=510 for Aust-ralian material indicating that, on a world-widebasis, this is probably a complex polyploid seriesrequiring a great deal more investigation. Countsof n=360 obtained for a population attributed toO. coriaceum from the Port Hills, Christchurch(Brownlie 1958, Lovis unpub.) indicate that herealso the species is cytologically intricate. Severalother names have been applied to New Zealandmaterial and the nature of these now requires fur-ther investigation. Meanwhile, O. coriaceum isconservatively retained until the taxonomy ofOphioglossum in New Zealand is properly resolved.
The possibility of a third species of Ophioglos-sum in New Zealand was raised by Harris (1955)who noted that Chatham Islands specimens yieldedspores exactly similar to O. vulgatum L. fromEurope. However, these specimens are now knownto have come from a sheet of mixed collectionsincluding both Chatham Island and Europeanmaterial.
MarattiaceaeOne species, M. salicina, is present in New Zealand.It is cytologically distinct from the tropical M.fraxinea with which it was earlier confused (seeLove et al. 1977).
OsmundaceaeThree genera of Osmundaceae occur in NewZealand — Osmunda, Todea and Leptopteris. Thefirst is represented only by the adventive Osmundaregalis, now well established in the North Islandespecially around the Waikato River. The nativeTodea and Leptopteris were all included in Todeaby Allan (1961) but are now almost universallyaccepted as separate genera — the former with thickleathery fronds, and sporangia confined to the lowerpinnae; the latter with thin translucent fronds, andsporangia scattered over all the pinnae. The twospecies of Leptopteris hybridise readily when theymeet in the wild, and such hybrids are now referredto L. X intermedia (Brownsey 1981). A biosyste-matic investigation of one such hybrid population(Brownsey 1981) indicated that although Fl hybridswere vigorous, had a normal meiosis, and pro-duced well-formed spores, they did not appear togive rise to an F2 generation.
SchizaeaceaeThe Schizaeaceae is retained here in its traditionalsense, although there is beguiling cytological andmorphological evidence for the recognition of a
separate Lygodiaceae (Bierhorst 1971, Pichi-Ser-molli 1977).
Three species of Schizaea (S. bifida, S. dicho-toma, and S. fistulosa) have usually been recog-nised in New Zealand together with a fourth taxon,S. fistulosa var. australis, variously regarded as agood alpine variety or merely a dwarfed form ofS. fistulosa. Brownlie (1965), with chromosomecounts of n=c.27O for S. fistulosa and n=94 for var.australis, provided cytological evidence which sup-ported the concept of two distinct taxa. Later, Lash(1966) carried out a morphological and cytologicalinvestigation of S. fistulosa for a M.Sc. thesis andsuggested (p. 49) that Brownlie's count of n=c.27Owas inadvertently made from a tapetal cell. His owninvestigations produced counts of n=94 andn=c. 150. However, whilst the larger counts weregenerally from larger plants he concluded that thecytological discontinuity could not be related to anyclear morphological discontinuity, and therefore didnot support the recognition of two separate taxa.More recently, Brownsey (unpub.) obtained a countof n=c. 190 from plants of S. fistulosa growing atWaikumete in Auckland — approximately twicethe number recorded by both Lash and Brownliefor var. australis. A more careful examination ofLash's illustration of the cell with c. 150 chromo-somes (fig. 17) suggests the presence of at least someunivalents. Failure of pairing could have resultedfrom hybridisation. The possibility therefore existsthat two distinct species are present in NewZealand, one with twice as many chromosomes asthe other, that they hybridise when they occurtogether, and that there is some failure of pairingof chromosomes in the hybrids resulting in a countof c. 150. Whether this is true in detail requires fur-ther investigation but we believe there is sufficientevidence to justify recognition of a fourth speciesin New Zealand. We refer it to S. australis for thetime being, though whether New Zealand materialis the same as the type from the Falkland Islandsalso needs verification.
PteridaceaeThe Pteridaceae is interpreted here in the broadsense of Tryon & Tryon (1982) to include all thecheilanthoid, gymnogrammoid, adiantoid, andpteridoid ferns, the origins of which, according tomost modern phyletic classifications, are to befound in the schizaeoid ferns with which they sharesome correspondence in chromosome number.
The genus Adiantum is represented in NewZealand by nine species, three more than recordedby Allan (1961). Two, A. capillus-veneris and thewidely cultivated A. raddianum*, have been intro-duced, the remainder being truly native. Tindale(1960c) showed that Australian and New Zealand
438 New Zealand Journal of Botany, 1985, Vol. 23
material previously referred to A. affine Willd.should be called A. cunninghamii Hook., the typespecimen of A. affine being clearly identifiable asA. capillus-veneris. Later, Tindale (1963b) distin-guished a new species, A. silvaticum, from Aust-ralian material of this complex with a distributionin southern Queensland and north and central NewSouth Wales, A. cunninghamii being confined toQueensland. More recently, in New Zealand, Parris& Croxall (1974) have proposed that Colenso's A.viridescens be readmitted as a species quite distinctfrom both A. cunninghamii and A. fulvum, but onewhich is very closely related to the Australian A.silvaticum. The question remains as to whether theQueensland plants of A. cunninghamii, with theirdistinctive morphology and tropical habitat, shouldcontinue to be referred to A. cunninghamii whichwas first described from New Zealand. Both A. vir-idescens and A. cunninghamii are listed here as NewZealand endemics subject to further investigation.
Another problem is manifest in the A. hispidu-lum complex. Parris (1980b) has suggested that bothA. hispidulum and A. pubescens are present in NewZealand, a possibility first hinted at by Sykes (1977)who referred Kermadec Island material to A.pubescens rather than the traditionally accepted A.hispidulum. Whether the differences in hair char-acters on the underside of the lamina identified byParris are sufficient to warrant the recognition ofseparate species is a matter of opinion. In theabsence of any obvious ecological differentiation,and the lack of observations on this complex fromthe remainder of its wide distribution, we prefer torecognise only one species, A. hispidulum, albeitwith two forms.
The genus Cheilanthes has been revised veryrecently in Australia by the late Helen Quirk (Quirket al. 1983). Her studies have shown that, as inEurope and America, the genus in Australia is cyto-logically complex and one in which apogamy playsa significant role. Although she did not specificallyinclude New Zealand in her investigation, she con-cluded that two species, C. distans and C. sieberi
subsp. sieberi (but not subsp. pseudovellea Quirk &Chambers), extend to New Zealand. A third spe-cies, C. tenuifolia, previously recorded in NewZealand, is now thought to be confined to Indo-Malaysia and tropical Australia. However, Quirket al. considered that a fourth species, C. austro-tenuifolia, with a distribution throughout southernAustralia probably occurs also in New Zealand.Quirk examined three type specimens of NewZealand origin but was unable to assign any of these,or any other material, with certainty to C. austro-tenuifolia. Indeed, she concluded (p. 521) that "...more work is needed on the New Zealand Chei-lanthes to determine their relationships, if any, tothe Australian species". This is especially pertinentin view of the fact that Australian C. austrotenui-folia is a sexually reproducing diploid, C. sieberi atriploid, and C. distans a probable tetraploid, thelatter two species reproducing apogamously. C. sie-beri is also an apogamous triploid here (Brownlie1957).
Two species of Pellaea, P. rotundifolia and P.fal-cata, have traditionally been recognised in NewZealand and are listed here. A third, as yet undes-cribed species, occurs around Wellington and in thedrier parts of Marlborough, Canterbury, and Otago.All three species have close relatives in Australia,and an investigation of the whole complex is inprogress (Brownsey, Given & Lovis, in prep.). Pre-viously published chromosome counts suggest thatfurther cytological investigation will be rewarding.Tindale (1972) gives "n=29 + 2, diploid hybridderivative (Manton)" for P. falcata var. nana inAustralia, whilst Brownlie (1954, 1957, 1961)reports n=58 for New Zealand P. falcata, and P.rotundifolia.
The genus Pteris in New Zealand and parts ofthe Pacific has been the subject of a Ph.D. thesisby Braggins (1975), and his investigations haveshown that significant nomenclatural changes willbe necessary. Until such time as his work is for-mally published, however, one adventive and fournative species are accepted here, including P. sax-atilis which has been shown to be cytologically dis-tinct from P. macilenta (Walker 1962).
* A more familiar name, particularly for cultivatedmaterial of this species, is A. cuneatum Langsd. et F.Fischer, but this is illegitimate because of the earlierhomonym A. cuneatum Forst. f., and most recent authorshave used the name A. raddianum C. Presl. However,Nair & Ghosh (1974) state that "A. raddianum Presl isdifferent from A. cuneatum Langsd. et Fisch. in mor-phology of leaf and propose instead the name A cunei-pinnulum for the latter taxon. They give no further detailsof the difference between the two, and cite no type orauthentic material examined. Until the types can beinvestigated we prefer to retain the name A. raddianum.
GleicheniaceaeWalker (1966) and Lovis (1977) have pointed outthe strong cytological evidence which supports themorphological recognition of five distinct taxawithin Gleichenia sens. lat. To some extent this isalso backed up by recent phytochemical work(Wallace et al. 1983). Holttum (1959) referred thesefive taxa to subgenera whilst Ching (1940) and,more recently, Crabbe et al. (1975) treat them asseparate genera. The names used by differentauthors vary but their concept of the entities
Brownsey et al.—Classification of New Zealand pteridophytes 439
involved is essentially similar. They are regardedhere as distinct genera of which three occur in NewZealand; Gleichenia sens. str. (n = 20, 22) with ulti-mate pinnules about 1 mm long bearing a singlesorus and having undivided veinlets; Sticherus(n=34) with much longer ultimate pinnules bear-ing several sori each of 4-5 sporangia, and havingonce-branched veinlets; and Dicranopteris (n=39)with longer ultimate pinnules bearing several soriof 6-10 sporangia and having veinlets at least twicebranched (see Holttum 1959, figs 1, 7, 8, 12, 15).
Identification of the New Zealand species ofSticherus and Dicranopteris is straight-forward butwithin Gleichenia sens. str. there are some awk-ward problems. Two fairly well defined species arepresent, together with an alpine form of less certainstatus. The relationship of these taxa to those inAustralia and S.E. Asia, and the correct nomencla-ture for them, is a very vexed question.
Central to the issue is the name G. circinnatapublished by Swartz in 1801 without precise local-ity, and only later (Swartz 1806) stated to be fromBotany Bay. Several more Australian species weresubsequently described by Robert Brown (1810)including G. microphylla and G. dicarpa. Brownindicated that G. microphylla and G. circinnatamight be synonymous but found Swartz's descrip-tion unsatisfactory for a firm decision. A nomen-clatural problem has arisen because of subsequentdifferent interpretations of the identity of G. cir-cinnata. Christensen (1906) considered it to be anearlier name for G. microphylla, and following hiswork Cheeseman (1906) used the names G. circin-nata and G. dicarpa for New Zealand material.Later, Christensen (1910) changed his mind andstated that G. circinnata was identical with G.dicarpa, with the result that Allan (1961) adoptedthe names G. circinnata and G. microphylla for theNew Zealand species. However, Holttum (1959)provided cogent reasons for rejecting Christensen'slater interpretation, and indicated that G. circin-nata and G. dicarpa were definitely not the same.He was unable to determine the real identity of G.circinnata (partly because of a problem of typifi-cation) and, in the circumstances, it is probably bestto abandon the name as a nomen ambiguum. Holt-tum accepted the name G. microphylla and includedNew Zealand within its range of distribution. Healso restored the name G. dicarpa, but perhaps sig-nificantly gave only Malaysia, Australia, and NewCaledonia for its distribution. Other authors (e.g.,Brownlie 1969, Willis 1970, Tindale 1972) have,however, continued to include New Zealand withinits range. The situation obviously requires clarifi-cation, including the possibility that G. hecisto-phylla might be an acceptable alternative name ifG. dicarpa is shown not to be a New Zealandspecies.
The status of the alpine form variously referredto G. dicarpa var. alpina or G. alpina requires fur-ther investigation both here and in Australia.
Grammitidaceae
Most modern authors have distinguished theGrammitidaceae from the Polypodiaceae, de la Sota(1973) in a review of the Polypodiaceae going sofar as to conclude (p. 242) that the two are "notclosely related". On the other hand, Tryon & Tryon(1982, p.685) state that "since there is no conclu-sive evidence supporting discrete evolutionarylineages, a single family is recognised". We havefollowed the majority opinion and accepted twofamilies.
The Grammitidaceae is interpreted here asincluding the genera Ctenopteris, Grammitis, andAnarthropteris. The latter was placed in the Poly-podiaceae by Allan (1961) but is now generallyregarded as more closely related to the Grammi-tidaceae, although sometimes separated off in thefamily Loxogrammaceae (e.g., Pichi Sermolli 1977).It has frequently been reported as occurring inVanuatu (e.g., Allan 1961), but is not listed for thatregion by Braithwaite (1975). We are unaware ofany collections from Vanuatu and believe it maybe a genus endemic to New Zealand.
The distinction between Ctenopteris with pin-nate fronds and Grammitis with entire fronds isaccepted here, despite the occurrence of occasionalintergeneric hybrids (Parris 1977). The revision ofNew Zealand Grammitis (Parris & Given 1976) isadopted in its entirety except for the purely nomen-clatural substitution of G. poeppigiana and G. rig-ida for G. armstrongii and G. crassa (Parris 1980a).
PolypodiaceaeThere are two current schools of thought regardingthe phylogenetic affinities of the Polypodiaceae,usually also including the Grammitidaceae,although Nayar (1970) has widely separated the twoin his scheme. The majority of recent authors (dela Sota 1973, Crabbe et al. 1975, Lovis 1977, PichiSermolli 1977) have allied the Polypodiaceae withthe Gleicheniaceae or Dipteridaceae largely on thebasis that this is an exindusiate line of ferns withabaxial sori. However, Jarrett (1980) has arguedstrongly that other characters, notably the structureof the sporangium and indumentum of the game-tophyte, indicate that the Polypodiaceae andGrammitidaceae are related to advanced indusiatefamilies. It is still too early to assess Jarrett's con-clusions since the full results of her survey and newclassification of the ferns are still awaited. Mean-while we continue to ally the Polypodiaceae withthe Gleicheniaceae.
440 New Zealand Journal of Botany, 1985, Vol. 23
The Polypodiaceae is a small and relativelyunimportant family in New Zealand with just onespecies each of Pyrrosia and the adventive Poly-podium, and three of Phymatosorus, the limits ofwhich are not in doubt although their generic affin-ity remains uncertain (de la Sota 1973). The speciesplaced in Phymatosorus were originally describedas Polypodium but were transferred to Microsorum(as Micwsorium) by Copeland (1947). This wasdisputed by Pichi Sermolli (1951) who thought theybetter corresponded to Phymatodes, but this lattername has now been shown to be illegitimate andPichi Sermolli (1973) has proposed the new genusPhymatosorus, referring twelve species, includingthe three New Zealand ones, to it. The genus Phy-matosorus is accepted here although some authori-ties (e.g., Tindale 1960a, 1961, 1972; Willis 1970)continue to use Copeland's Microsorum.
HymenophyllaceaeThe classification of the Hymenophyllaceae adoptedhere is a conservative one of convenience. Follow-ing Tryon & Tryon (1982), only two genera,Hymenophyllum, and Trichomanes, are recog-nised, and no further subdivision is attempted.Whilst appreciating that Hymenophyllum and Tri-chomanes are large and potentially subdivisibleumbrella genera, no entirely satisfactory naturalclassification of the filmy ferns has yet beenachieved, and it is therefore thought best to retainthe larger, more readily identifiable groupings untilsuch time as a world monograph is published.Morton (1968) proposed six genera, Copeland(1947) 34 genera and Pichi Sermolli (1977) as manyas 42 genera. A reassessment of these classificationsis currently being carried out by Iwatsuki (1975,1977a,b, 1978, 1981, 1982), and it is hoped thatthis may lead to a more generally acceptable sub-division*. Lovis (1977) has summarised ourknowledge of chromosome numbers in the familyand has stressed the importance of further cyto-logical research, for it is evident that chromosomecounts and karyotype analysis will ultimately proveto be of the utmost importance in the classificationof the Hymenophyllaceae. Unfortunately its value
* Note added in proof: Iwatsuki (Acta Phytotax. Geobot.35: 165-179, 1984) has just published a new scheme ofclassification for the filmy ferns based chiefly on Asiaticspecies. He states that the classical bigeneric system isnot natural at all and, instead, recognises eight genera,some of which are subdivided into several subgenera.The genera represented in New Zealand are Hymeno-phyllum, Sphaerocionium, Crepidomanes, Cephalo-manes and Cardiomanes. More time is needed to assessthis new classification but, if accepted, new combina-tions would be required for most of the New Zealandspecies here placed in Trichomanes.
so far has been disappointingly negative in the sensethat taxa such as Mecodium, Meringium, andHymenophyllum sens, str., recognised on mor-phological grounds, have proved to be cytologicallyheterogeneous and therefore, very possibly,unnaturally defined. Preliminary phytochemicalwork on the family (Markham & Wallace 1980, p.418, Wallace et al. 1982) suggests "... that a studyof the polyphenolics of the species ... should be auseful aid in delineating lower taxa" although, par-adoxically, the authors note that the "... all inclu-sive genera, Hymenophyllum and Trichomanes, arenot clearly delineated by their polyphenoliccharacteristics".
In New Zealand, the Hymenophyllaceae with 27species is the largest family of ferns, and Hymen-ophyllum sens. lat. with 21 species the largest genus.Despite the high number of species, however, thetaxonomy of the group at this level is generally wellresolved. Parris & Croxall (1972) showed recentlythat H. cupressiforme is present here, distinct fromboth H. revolutum and H. peltatum. The majorremaining area of difficulty concerns the H. aus-trale aggregate where taxa such as H. atrovirens, H.montanum and H. flexuosum need investigation inrelation to each other and to their Australian coun-terparts. Brownlie (1959) suggested that all NewZealand material previously referred to H. australewas in fact either H. atrovirens or H. flexuosumand that both species were distinct from the Aust-ralian H. australe. This interpretation has beenfollowed both by us and by Croxall (1975) who gaveonly an Australian distribution for H. australe, withthe closely related H. atrovirens in New Zealand.Tindale (1963a), however, reduced H. atrovirens tosynonymy with H. australe, leaving only H. flex-uosum as a distinct New Zealand taxon. On theother hand, Allan (1961) accepted H. montanumas a good species in addition to both H. atrovirensand H. flexuosum, and there is field evidence tosupport this treatment. The limits of the individualtaxa and their correct nomenclature require furtherstudy.
More detailed cytological investigation of thefamily is also desirable, both in species for whichcounts are not yet known and in complexes suchas H. sanguinolentum/villosum where both n = 36and n = 72 have been reported for H. sanguinolen-tum (Brownlie 1954, 1961). Further work on thiscomplex is being carried out by Lovis & Daellen-bach. Lovis has also shown (1982) that Colenso'sH. pygmaeum is a synonym of H. minimum.
DicksoniaceaeHolttum & Sen (1961) included all tree ferns withinthe one family, Cyatheaceae, but Holttum (in Holt-tum & Edwards 1983) has now changed his mind,
Brownsey et al.—Classification of New Zealand pteridophytes 441
and hence the family Dicksoniaceae is maintainedhere.
CyatheaceaeA completely new classification of the Cyathea-ceae, based largely on stipe scale characteristics, hasrecently been proposed by Tryon (1970) in whichsix separate genera replace Cyathea sens. lat. Ofthese, only Alsophila and Sphaeropteris occur inNew Zealand. The scheme is still highly contro-versial, and very recently has been criticised indetail by Holttum (in Holttum & Edwards 1983).He has put forward an alternative scheme in whichthe genus is divided into two subgenera, Cyatheaand Sphaeropteris, each with a number of sectionsand subsections. It should be noted that the differ-ence between the two concepts of Sphaeropteris isnot merely one of rank but also of circumscription.Tryon's scheme is open to criticism because of theabundant evidence of hybridisation between spe-cies assigned by him to different genera. Most sig-nificantly, Conant & Cooper-Driver (1980) haveshown that Alsophila bryophila X Nephelea porto-ricensis and Alsophila dryopteroides X Nepheleaportoricensis are examples of allohomoploid hybridspeciation in the sense of Grant (1971). However,to our minds, this type of micro-evolutionary inter-action, which results in fertile diploid hybrids, isnot acceptable between validly distinct genera, andin this instance, indicates that Tryon's genera areincorrectly defined. Holttum's scheme is also pre-ferred for his account of the origin of indusia inthe family and, accordingly, a conservative nomen-clature is followed here.
Fortunately, at the species level, the tree ferns inNew Zealand pose no obvious taxonomic prob-lems now that the presence of Cyathea cunning-hamii has been confirmed (Tindale 1956, Holttum1964, Brownsey 1979a).
Thelypteridaceae
Our classification of the Thelypteridaceae followsthat proposed by Holttum (1971) for the Old Worldrepresentatives. Thus the five species of Thelypterisaccepted in New Zealand by Allan (1961) are nowdistributed in five separate genera. Treatment ofthe indigenous species of Macrothelypteris, Pneu-matopteris, and Christella is taken from Holttum'smonographs (1969, 1973b, 1976), although theprobability that two species of Christella may occurin New Zealand, one in thermal areas and the Ker-madec Islands, and one in north Auckland, is beinginvestigated (Given, Sykes & Bartlett, in prep.). Thetwo remaining taxa, Thelypteris confluens andCyclosorus interruptus, are components of geo-graphically widespread aggregates, being cytologi-cally and morphologically complex, and
nomenclaturally tortuous. Problems involved in thetwo cases are discussed respectively by Morton(1967) and Holttum (1973c). More recently, Holt-tum (1977b) has monographed the Pacific andAustralian representatives of the family Thelypter-idaceae and suggested areas where further work isdesirable.
LoxsomataceaeThe systematic position of the family Loxsoma-taceae has always been a matter of conjecture.Brownsey (1975) obtained a chromosome count ofn = 50 in the endemic, monotypic genus Loxsoma,a number so distinct that it only emphasised theisolated evolutionary position of the family. Morerecently, however, Wagner (1980) has proposed thatthe closely related neotropical genus Loxsomopsiswith n=46 might have an affinity with the denn-staedtioid ferns. The close relationship betweenLoxsomopsis and Loxsoma has been confirmed bya study of their flavonoids (Markham & Given1979). Brownsey (1983b) now suggests that theymay occupy a position between the Dennstaedti-aceae and Cyatheaceae, which is cytologically con-sistent with Lovis's (1977, p. 303) idea that theDennstaedtiaceae originated by a long series ofaneuploid reductions from a source in theCyatheaceae.
DennstaedtiaceaeThe Dennstaedtiaceae is interpreted here in a ratherbroad sense to include all the dennstaedtioid,hypolepidoid, and lindsaeoid ferns — groups whichare consigned to independent families by Nayar(1970) and Pichi Sermolli (1977). In taking thiscontrary view we are much influenced not only bythe recent review of Mickel (1973) but also by theintriguing cytological theory proposed by Lovis(1977, p. 307) in the light of available chromosomecounts that "the Dennstaedtiaceae is based on onevery ancient long aneuploid series". The validityof this novel suggestion remains to be proved, butundoubtedly the Dennstaedtiaceae is both a familyof taxonomically ill-defined genera, and one whichis critical to any phylogenetic comprehension of themodern ferns.
Within New Zealand the largest genus in thefamily is Hypolepis which has just been revised byBrownsey & Chinnock (1984) who accept sevenspecies and exclude three other commonly mis-applied names (H. punctata, H. rugosula, and H.tenuifolia). One species, H. distans, is morpholog-ically and cytologically distinct from the others; thepossibility that it should be referred to a separategenus, and the evolutionary history of the hypo-lepidoid ferns in general, are discussed by Brown-sey (1983b).
442 New Zealand Journal of Botany, 1985, Vol. 23
The remaining members of the New ZealandDennstaedtiaceae pose no real problems. Lindsaeain Australasia has recently been monographed byKramer & Tindale (1976) and their three NewZealand species are accepted here. Leptolepia, Pae-sia, Pteridium, and Histiopteris are all monotypicin this country, although Brownsey (1983b) ques-tions whether Histiopteris should really be closelyallied with the others. The inherent difficulties ofattempting a classification of bracken throughoutthe world are well-known and have recently beendiscussed by Page (1976). Page accepts Tryon's(1941) taxonomic treatment of Pteridium as amonotypic genus with many varieties throughoutthe world. However, we have followed Wakefield(1957), Smith (1966), Holttum (1968), Willis (1970),Tindale (1972), Brownlie (1969, 1977), and Chin-nock (1978) in raising the Australasian and Pacificform of bracken to species status.
AspleniaceaeThe Aspleniaceae is interpreted here in its moretraditional sense, involving only the genus Asplen-ium and its satellite genera, rather than in the broadsense of Crabbe et al. (1975) who include also theathyrioid, tectarioid, and dryopteroid ferns. Thecytological evidence alone (Lovis 1977) providessufficient grounds for retaining the asplenioid fernsas a distinct group.
Asplenium in New Zealand has been revised byBrownsey (1977a,b) and his treatment is acceptedhere, save only that the name A. oblongifolium issubstituted for the illegitimate A. lucidum (Brown-sey 1979b). A. pauperequitum, endemic to the PoorKnights Islands (Brownsey & Jackson 1984), andA. chathamense, endemic to the Chatham Islands(Brownsey 1985), have since been added to the flora,and the range of A. terrestre, previously consideredendemic, extended to Victoria and Tasmania(Brownsey 1983a). The hexaploid subspecies of A.trichomanes (Lovis, unpub.) remains undescribed,whilst forms of the A. flaccidum aggregate on theKermadec Islands and Antipodes Island requirefurther investigation.
Pleurosorus is monotypic in New Zealand andhas been investigated by both Given (1972) andSalvo et al. (1982). In line with recent trends tosubmerge the satellite genera of Asplenium, the lat-ter authors reduce Pleurosorus to a subgenus ofAsplenium, but we prefer to maintain them asseparate genera for the reasons outlined by Lovis(1973). Salvo et al. also propose reducing the threeknown species of Pleurosorus to subspecies of onepolymorphic aggregate (Asplenium subglandu-losum in their scheme), in our opinion a retrogradestep since it obscures the very remarkable distri-bution of this genus with populations in Spain,
Chile and Argentina, and Australia and NewZealand.
Dryopteridaceae
Our concept of the Dryopteridaceae is similar tothat of Nayar (1970) and Lovis (1977), and includesall the athyrioid, tectarioid, and dryopteroid ferns.It is at variance with Crabbe et al. (1975) whoinclude also the Aspleniaceae (separated off by uson cytological grounds), and with other authorsincluding Pichi Sermolli (1977) who maintain adistinction between the Athyriaceae and Dryopter-idaceae (Aspidiaceae). Sledge (1973) has discussedthe reasons why this latter distinction is not entirelysatisfactory.
The Dryopteridaceae in New Zealand include ahigher proportion of adventive ferns than any otherfamily and this, together with some importantchanges in the circumscription of individual gen-era, has contrived to give the family a totally dif-ferent complexion to that presented by Allan (1961).
Four athyrioid genera are present — Athyrium,Deparia, Diplazium, and Cystopteris. The first threegenera were previously included in Athyrium sens,lat., but this large umbrella genus is now usuallyregarded as being too broad in its circumscription.Various attempts to subdivide it have been made,the most recent by Kato (1977) who summarisesthe earlier proposals. A distinction now seemsgenerally agreed between Diplazium with elongatedsori arranged singly or back to back along a vein,and Athyrium with sori either hooked or horse-shoeshaped across a vein, or reniform. Cytological evi-dence lends support to the naturalness of these gen-era with x=40 in Athyrium and x=41 in Diplazium(Lovis 1977). Athyrium sens. str. is represented inNew Zealand only by the introduced A. filix-fem-ina, and Diplazium by D. australe, shared also withAustralia. Kato (1977) departs from earlier classi-fications by adopting the genus Deparia Hook, etGrev. in a broad sense to include also Lunathyr-ium Koidzumi, Dryoathyrium Ching, and Athy-riopsis Ching. With x=40, the genus is fairly clearlydistinguished by the presence of multicellular hairson the lamina, and by the groove on the upper sur-face of the main rachis not opening to admit thegroove of the pinna rachises. Kato (1984) has justcompleted a monograph of Deparia in which theNew Zealand plant previously known variously asAthyrium japonicum or Lunathyrium japonicum isreferred to Deparia petersenii subsp. congrua ratherthan D. japonica which is confined to Japan. Healso recognises the enigmatic Asplenium umbro-sum var. tenuifolium Kirk as a distinct endemicspecies, Deparia tenuifolia, with a tripinnate frondcompared to the bipinnate frond of D. petersenii.
Cystopteris with x=42 and with round sori and
Brownsey et al.—Classification of New Zealand pteridophytes 443
ovate indusia is readily distinguished morpholog-ically and cytologically from the other genera. Ithas been monographed by Blasdell (1963) but hisconclusions have not been enthusiastically receivedby most workers. In contrast to earlier authors whohad allied the New Zealand plant to the EuropeanC. fragilis, he referred South American and Aus-tralasian material to C. fragilis var. apiiformis —a combination based on a type from the FalklandIslands. Whether or not the South American plantis truly identical to that in Australasia remains tobe established, but in any event the name C. tas-manica (as a species or a variety) based on an Aust-ralian type has priority over C. apiiformis whenapplied to Australasian material. Blasdell made nomention of C. tasmanica in his monograph, but inthe opinion of the present authors, and first pro-posed by Lovis (1959), the Australian and NewZealand material is sufficiently distinct to warrantspecies status with this name. There is also presentin New Zealand an adventive species which isreferable to the European C. fragilis and which isquite distinct from C. tasmanica. This adventiveplant has evidently been here from early Europeantimes because Colenso's C. laciniatus is based onsuch a form.
The largest and most important genus of theDryopteridaceae in New Zealand is Polystichum.Four native species have traditionally been recog-nised, but a fifth, probably undescribed, is presenton the Chatham Islands, and another curious formon the Snares. The Australian P. proliferum, dis-tinguished from the native P. vestitum on scalecharacters and its bulbiferous frond, also occurssporadically in New Zealand where it is probablyadventive. Polystichum lentum and a cultivatedform of the European P. setiferum have also escapedin some places.
Two other adventive genera occur in NewZealand. One species of Cyrtomium is found inparts of the northern North Island whilst furthersouth, particularly in Canterbury, three species ofDryopteris have been recorded. The most wide-spread is D. filix-mas, but sporadic populations ofits apogamous triploid relative D. affinis have alsobeen noted. In Dunedin, where D. affinis is actuallymore abundant than D. filix-mas, occasionalhybrids have been found where the two species growtogether (Lovis & Brownsey, unpub.). Plants of D.affinis so far investigated have been triploid(Brownsey, unpub.) but whether any of the otherEuropean cytotypes in this complex are also pres-ent remains to be established. A third species, D.dilatata, has been collected occasionally.
The genus Lastreopsis has recently been mono-graphed by Tindale (1965) and her treatment isadopted here. Lastreopsis hispida, L. velutina, andL. glabella, are recognised together with a form
from the Kermadec Islands thought to be a newspecies but still awaiting formal description {see alsoSykes 1977). Tindale also distinguished, as subsp.pentangularis, tetraploid populations of L. micro-sora occurring in New Zealand which were mor-phologically separable from diploid populations inAustralia. However, she suggested that diploidplants might also occur in New Zealand, and thiswould bear further investigation.
The species referred to Lastreopsis by Tindalewere previously included in Ctenitis and Rumohra(e.g., Cheeseman 1925, Allan 1961). Two other spe-cies of Rumohra were also listed by Allan, but oneof them, R. aristata from the Kermadecs, has nowbeen transferred to Arachniodes (Tindale 1961).Tindale herself referred to Arachniodes as "a ratherunsatisfactory genus placed mid-way betweenDryopteris sens, stricto and Polystichum" andalthough she attempted to re-define the three gen-era more clearly Sledge (1973) considers Arach-niodes to be "justified more as a genus ofconvenience than as a natural one". In accom-modating elements which combine some featuresof both Polystichum and Dryopteris it serves theimportant practical function of keeping these twomuch larger genera taxonomically distinct.
The remaining species of Rumohra in the NewZealand flora, R. adiantiformis, is the subject ofconsiderable debate. Though the genus, with thisone wide-ranging southern hemisphere species andfive others endemic to Madagascar, appears to besatisfactorily circumscribed, its placement in theDryopteridaceae is highly controversial. Mostmodern authorities (e.g., Holttum 1968, p. 484,Wakefield 1957, Tindale 1961, 1972, Crabbe et al.1975) include it with the Davalliaceae on accountof its creeping dorsiventral rhizome and davallioidmain rachis. Recently, however, Kato (1974) andPichi Sermolli (1977) have shown that these char-acters are found elsewhere in the Dryopteridaceaebut that features such as the peltate orbicular indu-sia, the nature of the petiolar anatomy, and theabsence of articulation at the junction of stipe andrhizome are alien to the concept of davallioid ferns.Accordingly, we follow them and include Rumohrawith the Dryopteridaceae, albeit as a somewhatanomalous element.
DavalliaceaeThe Davalliaceae is construed here in a broad senseto include both the davallioid and oleandroid ferns.The family is of minor importance in New Zealandwith only one species of Arthropteris, three taxa ofNephrolepis, all of limited distribution, and a singlespecies of Davallia, previously considered to beendemic to the Three Kings Islands but recentlydiscovered in Puketi Forest, Northland (P. Bel-lingham, pers. comm.).
444 New Zealand Journal of Botany, 1985, Vol. 23
Nephrolepis is in urgent need of a world-widerevision and the nomenclature adopted here forNew Zealand material would almost certainly needto be changed in such a monograph. Nevertheless,Sykes (1977) gives good reasons for using the nameN. hirsutula for Kermadec Island plants previouslyreferred to N. exaltata. Two other taxa are presentin the North Island — one native and confined tothermal areas, the other a cultivated strain nownaturalised in many warmer parts of the country.They have often been regarded as the same speciesin the past, but the cultivated plant is generallylarger and has underground tubers — a feature fre-quently absent from native populations. The cor-rect nomenclature for these taxa is still veryuncertain.
Central to any revision of Nephrolepis and to thetaxonomic problems posed by New Zealandmaterial is the question of the identity of Polypo-dium cordifolium L., later transferred by Presl tothe genus Nephrolepis and subsequently creditedwith a widespread tropical distribution extendingas far north as Japan and as far south as NewZealand. Pichi Sermolli (1968) was able to showthat the type of Linnaeus's Polypodium cordifoliumis in fact plate 71 of Plumier's "Traite des Fougeresde L'Amerique" illustrating a plant collected "dansune forest de la Bande du Sud, dans l'isle SaintDomingue". However the identity of the plantremains unclear and Pichi Sermolli was forced toconclude "I think that Plumier's plate 71, althoughrough, reproduces a species of Nephrolepis. How-ever, whether it shows the species currently calledNephrolepis cordifolia or another species of thegenus is not wholly certain. Perhaps a research inthe region in which it was originally collected byPlumier could afford a final answer to this prob-lem. For the time being I use the name Nephrolepiscordifolia in the current sense". However, PichiSermolli goes on to show that N. cordifolia, as con-strued by Christensen (1906), is in fact an assem-blage of six closely related species. Relevant to theNew Zealand problem is his recognition of N. tub-erosa (Bory ex Willd.) C. Presl with a distributionin "Malgassia, Ceylon, India, N. Caledonia andcertainly elsewhere" distinct from N. cordifolia"widely distributed in tropical America and in thetropics of the Old World, but not in Africa". Thisdistinction has recently been accepted by Brownlie(1977) for Fijian material which he refers to N.tuberosa.
However, in an earlier paper, Alston & Bonner(1956) had also concluded that Polypodium cordi-folium L. was based on Plumier's plate 71. Theysuggested that it appeared to represent the Amer-ican plant Nephrolepis occidentals (Kuhn) Kuntze,and proposed that the correct name for the Old
World plant, specifically including "Japan, NewZealand, (and) tropical Asia", was N. auriculata (L.)Trimen. This conclusion has been accepted,amongst others, by Nakaike (1975) in Japan andLi (1975) in Taiwan. Unfortunately, however, PichiSermolli (1968) refers neither to this name, nor toAlston & Bonner's paper. It therefore remains tobe established whether N. auriculata and N. tub-erosa are the same (a problem beyond the scope ofthis paper) but if they are then N. auriculata wouldtake priority as the older name.
The problem in New Zealand is confounded stillfurther by the presence of a native species and ahorticultural variety now widely established.Nephrolepis species are commonly cultivated inmany parts of the world as "Sword ferns" or "Bos-ton ferns" and many ornamental varieties andstrains of the wild species have been established incultivation. Morton (1958) describes some of themore important of these but makes the point thatN. cordifolia "is the only species that bears 'tubers'". The adventive plant in New Zealand certainlybears tubers and would therefore seem to belongto this aggregate, whatever its correct nomencla-ture might prove to be. The native plant, though,appears to lack tubers (see, for example, Sykes1977). B. W. McAlpin, currently working on theclassification of Nephrolepis cultivars, suggests (pers.comm.) that this is taxonomically very significantand an indication that the native plant may be acompletely different species. Meanwhile, until awide-ranging study of Nephrolepis is carried out,the two taxa present in New Zealand are conserv-atively referred to N. cordifolia.
BlechnaceaeThe Blechnaceae is a clearly defined and univer-sally accepted family, currently represented in NewZealand by Doodia and Blechnum. However, twoQueensland species have recently been transferredto the new genus Pteridoblechnum by Hennipman(1976) who suggests that Blechnum fraseri, whichhas always appeared somewhat out of place inBlechnum, may also belong here. Further investi-gation is required before formalising the transfer.
Doodia has been revised by Parris (1972) and hertreatment is accepted here, except that New Zealandplants previously referred to the Australian D. cau-data are now recognised as a distinct species, D.mollis (Parris 1980a). An extant population of D.aspera in New Zealand is also recorded by Parris(1980a).
Blechnum is an extremely important genus inNew Zealand, being second only to Hymenophyl-lum in terms of the number of species. A cytotax-onomic investigation of the local representativeswas the subject of an M.Sc. thesis by Chambers
Brownsey et al.—Classification of New Zealand pteridophytes 445
(1954) which is slowly expanding into a world-widemonograph. Recently Given (in prep.) has sug-gested that the Blechnum capense aggregate, longrecognised as exceedingly polymorphic, comprisesfive New Zealand taxa, with close relatives in Aus-tralia and South Africa. Despite the fact that someof these taxa are amongst the most common fernsin New Zealand, only two have legitimate namesat present. The name B. capense (L.) Schldl., pre-viously used for the best known of these taxa, ispredated by B. capense Burm. f. but, in any case,is now known to apply only to South Africanmaterial; New Zealand plants once referred to thisspecies require a different name. They include twoforms. One ("black spot") is characterised by largefronds with numerous pairs of pinnae whichdecrease markedly in length towards the base ofthe frond, and stipe scales with an obvious blackcentre; this form occurs in a wide variety of hab-itats but especially on road banks and cliff sides(Crookes 1963, p. 312). The other ("mountain") hasa more truncate base to the frond and bronzecoloured pinnae with undulate margins, and occursprimarily in mountain regions of the South Island(Crookes 1963, p. 285). Plants with fronds similarto "black spot" in outline but smaller in size, withuniformly pale brown stipe scales, and with moredistant, thin textured, obtuse pinnae, occur inswamps and other damp habitats; these are refer-able to the Australian species, B. minus (Crookes1963, p. 283 — as B. capense "swamp form"). Thename B. minus has been used incorrectly in NewZealand by Allan (1961) and others for a plantwhich should be called B. procerum. This is closelyrelated to the Australian B. wattsii Tindale (1963b),and has relatively few pairs of more or less equallysized, short, broad pinnae with rounded apices; itoccurs most commonly on forest floors (Crookes1963, p. 281 — as B. minus.) The morphologicalcharacteristics of these forms have also been wellillustrated recently by Molloy (1983). The fifthtaxon commonly known as the "Green Bay form"(Crookes 1963, p. 287) occurs in steep-sided gulliesand cliffs, often in coastal habitats; it has fronddimensions comparable to "black spot", but is del-toid in outline with a long, thick stipe and numer-ous pairs of pinnae which decrease in length towardsthe apex of the frond.
Another problem is manifest in the B.norfolkianum/chambersii/membranaceum aggre-gate, a group of three species often difficult to dis-tinguish satisfactorily and complicated by thepresence of hybrids in areas where two or moreoccur together, as well as by a sorry history ofnomenclatural errors. B. chambersii is a new nameproposed by Tindale (1972) for the fern originallyknown as B. lanceolatum. The latter name is ille-gitimate because of an earlier homonym, and Tin-
dale (1960b) initially suggested B. aggregatum asan alternative. However, the type specimen of thisname subsequently proved to be a hybrid (B.chambersii X membranaceum) and the name B.chambersii was adopted instead. Brownlie (1977)then proposed a new combination, B. doodioides,based on Fijian material which he suggestedextended to Australia and New Zealand; being anearlier name it took preference over B. chambersii.However, Parris (1980a) has pointed out thatBrownlie's B. doodioides is a later homonym of B.doodioides Hook., and hence B. chambersii remainsthe correct name for Australasian material.
The remaining species of Blechnum in NewZealand appear to be fairly clearly defined now thatWakefield (1956) has separated the local B. colen-soi from the Australian B. patersonii. Nevertheless,discrepancies in chromosome number betweenTasmanian and New Zealand representatives of thegenus suggest that further cytological investigationin the two countries is desirable. Thus, B. penna-marina and B. vulcanicum apparently have n=33in Tasmania (Quinn 1961) but n=34 in NewZealand (Brownlie 1954). Also, a polyploid serieshas been detected in B. fluviatile with Tasmanianrepresentatives showing n=99, and New Zealandspecimens n=66 and n=33 (Chambers 1954) orn=34 (Brownlie 1954). Lovis (1977) has alreadypointed to the potential value of karyotype analysisin Blechnum, and the Australasian region with itsabundance of species and variation in chromo-some number would be a rich area for such a study.
MarsileaceaeThe sole New Zealand representative is Pilularianovae-zelandiae which is only doubtfully distinctfrom the Australian P. novae-hollandiae A. Br.
SalviniaceaeOne adventive species of Salvinia is present in thewarmer parts of New Zealand and is referred tothe newly described S. molesta (Mitchell 1974). Atvarious times the names S. natans (L.) All., S. hert-zogii Sota and S. auriculata Aubl. have been usedfor New Zealand material but are now believed tohave been mis-applied, S. molesta being distin-guished by its small male sporocarps bearing emptysporangia.
Two species of Azolla are present in New Zealand— a widespread native species previously called A.rubra and a recently arrived adventive species, A.pinnata, still confined to the northern North Island.Both occur also in Australia where A. rubra, thetype of which is Australian, has been reduced tosynonymy with the American A. filiculoides (Wake-field 1957, Smith 1966, Willis 1970, Chinnock 1978)
446 New Zealand Journal of Botany, 1985, Vol. 23
or at best retained as a variety of that species (Tin-dale 1972). This follows the work of Svenson (1944)on the New World species of Azolla who foundthat the minor morphological characteristics dis-tinguishing A. rubra were also present scatteredthrough the range of variation of A. filiculoides inAmerica. The latter name is therefore adopted herefor the New Zealand plant.
SYNONYMIC CHECKLIST OF VALIDLYPUBLISHED PTERIDOPHYTE NAMES
There follows a list of all validly published namesand combinations either based on New Zealandtypes or used by authors in reference to the NewZealand flora. The taxa are arranged according tothe classification given above. Nomina nuda havebeen excluded and hybrid combinations areincluded only when they have been given a specificepithet (e.g., Doodia X digena) or where namesoriginally used for species have been shown to bebased on hybrid material (e.g., Blechnum X aggre-gatum). Hybrid names are listed at the end of theappropriate generic section.
Synonyms for each accepted species are given inorder of publication of the type on which they arebased. For geographically widespread species onlythe more important synonyms and those based onNew Zealand material are given. By no means allthe types have been examined by us, and unless wehave found evidence to the contrary, judgementsof earlier authors have been accepted. Where thereare contradictory opinions or no reliable decisioncan be made, lists of taxa requiring further investi-gation are given, separate from the synonymy butunder the name of the most closely related acceptedspecies.
Adventive species are included with the nativespecies and are indicated with an asterisk. Onlybasionyms and particularly important synonymsare given for these species.
Mistaken identifications are listed in the custom-ary fashion. For example (p. 447), authors erro-neously identifying New Zealand material ofLycopodium australianum Herter as L. selago L.are listed after the entry "Lycopodium selago auctt.non L. (1753): ....". Only the standard fern florasof New Zealand have been checked for this typeof inaccuracy, including the following works: Rich-ard (1832), Cunningham (1837), Raoul (1846),Hooker (1855, 1867), von Mueller (1864), Thom-son (1882), Field (1890), Cheeseman (1906, 1925),Dobbie (1921, 1931, 1951), Allan (1961), andCrookes (1963).
Names of taxa dubiously or erroneously recordedfor New Zealand are listed alphabetically on p. 472.
Where necessary an indication of their currentlyaccepted nomenclature is given, together with anysource listing their occurrence in New Zealand.
Authors names have been abbreviated accordingto the Kew Draft Index (Halliday et al. 1980) withthe following two exceptions: Cheesem. = T. F.Cheeseman; Col. = W. Colenso. Titles of journalsfollow the abbreviations in Botanico PeriodicumHuntianum, and of monographs those in Taxon-omic Literature (Stafleu & Cowan 1976-83), exceptthat the words New Zealand and Nouvelle-Zelandehave consistently been abbreviated to the lettersN.Z., and the title Essai d'une flore de la Nouvelle-Zelande (Richard 1832) to Essai Fl. N.Z. Dates ofpublication for works issued in parts are taken fromStafleu (1967) and Stafleu & Cowan (1976-83)except for the two fern papers by Colenso in theTasmanian Journal of Natural Science now knownto have been published in 1843 and 1845 (Plomley1969).
In a work of this scale mistakes in the placing ofsynonyms will inevitably have occurred. It is hoped,however, that very few names relevant to the NewZealand pteridophyte flora have actually beenoverlooked, and that this listing will serve as a basisfor future taxonomic research.
