I was staggered recently when I opened a pageon the web. Its URL was www.flowercouncil.org,the website of the Flower Council of Holland.Under Novelties 2004, I found a reference tonew cultivars and hybrids that I did not know(see article p.13 this Newsletter) G. ‘Misty Red’,G. ‘Yovel’. I have some information on G. ‘MistyRed’ but G. ‘Yovel’, the fourth most popularcultivar sold at the Dutch Flower Auctions is amystery. The number of blooms of G. ‘Misty Red’being sold was amazing. It certainly shows thevalue of research. We are not that far behindbut we sure are missing out on something.

I recently joined a walk organised by the FernStudy Group along Mooney Mooney creek nearGosford, New South Wales. Ostensibly this wasto show support for my wife’s interest in 21ferns that had been collected previously on thiswalk. However, the walkers also envisagedpassing Grevillea shiressii and I was keen tosee it again. I had been there nearly 20 yearsago with the late Pat Akkersdyk. It is aninteresting and relatively easy walk for which Ihave compiled a flora list in memory of Pat, thatindefatigable and inspirational list maker. Pat wasfamous for walking on a given track, compilinga list of plants seen on the way, and writing itdown for others to use. Sutherland Group has alist of all Pat’s lists. A list of lists if you like.

Grevillea shiressii is still going strong in thedeep depositional alluvium beside the creek,within the floodzone surely, but rarely asrobustly as plants seen in cultivation. Mostplants had main stems less than 20cm wide andwere relatively spindly, single-stemmed plants.Some were in flower (May 22). The GrevilleaSG will do a walk here next year. Also seenwere a few plants of Grevillea linearifolia.

While in the area, I took the opportunity tocall on Don McGillivray who lives at PointClare. It is 20 years since Don retired from theNSW Herbarium because of the effects ofParkinson’s Disease which continues to ravageand torture this wonderful man. His wife andcarer, June, welcomed us in and we spent amemorable few hours in the company of thegreat man whose mind is still as alert and keen

as ever. Don showed me the Engler medal andletter, written from Hungary where it waspresented in absentia, for the most significanttaxonomic monograph published in 1993.Never has so deserving a recipient been soappropriately acknowledged. I regularly use thework in my own research and have the greatestadmiration for its contents and author. Donturns 70 on 26 August 2005.

Neil and I are currently working on a new book,the title of which is still undecided, but thecontents will reflect a treatment of the HybridGrevilleas. It is interesting, to me at least, thatwhile much attention is focussed on rare wildspecies, deservedly so, many hybrids oncepopular and widely grown have quietly andunexpectedly slipped into extinction. I havecompiled a list of plants that we can no longerfind in gardens around us. Can any of youhelp? If so, please let us know.

I am currently experiencing email problemssince my ISP provider of ten years or so soldout to a company in Toowoomba. The domainname australians.com was not included inthe sale and the owners have decided to shutit down. The service provided by the newprovider is vastly inferior and I doubt that I willbe there long. My current temporary emailaddress is [email protected] but may have toalter shortly. Neil Marriot’s email address [email protected].

We are currently compiling a list of hybrids thatno longer appear in the nursery trade lists andare not known to us in the gardens we visit.Perhaps you have one of them. Let us know ifyou would like to help. We will probably ask youfor a flowering specimen at some stage. Listnext newsletter.

Cas Liber reports a new occurence ofGrevillea shiressii

Cas was in Pearl Beach staying with familyfriends and a woman 2 doors up discoveredG. shiressii on her property about 100minland from the beach on a creek margin.Apparently a specimen has gone off to theherbarium.

Page 3: Newsletter No.71

The on-line catalogue was very successful alsoand generated much interest, resulting inpurchases of plants far in excess of what wasexpected. I still have about $2000 worth ofplants left over if anyone is interested in doinga deal. The display of memorabilia mounted byRay Brown on the Flinders expedition andcontemporaneous explorers, including theFrench, was outstanding and a real credit to hisindividual enthusiasm and capacity.

I would like to pay special homage to GordonMeiklejohn, Bruce Wallace and Hessel & DotSaunders, Christine Guthrie and partner,Bruce, Ken & Elaine Arnold, Tony Henderson,Beth and Ken Forbes, Kyril Taylor, personalfriends, all members of the SG who supportedthe event by manning the stalls, all members ofthe Australian Plant Society especiallySutherland and MacArthur groups who assistedor bought plants.

This year I spent a considerable amount ofpersonal effort (2 months) on the event. The SGis now the principal supplier of plants and wesourced them from a wide range of wholesalenurseries, bringing them in from near and far.The event achieved a profit of approximately$10 000 and the money has been earmarkedfor DNA research into the relationship betweenHakea and Grevillea. This research will beconducted through the Royal Botanic Gardens,Peter Weston supervising. An amount of $5000has already been earmarked to get thingsunder way. This is cutting edge taxonomicreseaarch and the Study Group is proud tomake such an important contribution to an areaof work receiving poor Government supportat present.

Autumn Plant Sale Report

Well, the plant sale is over once again. In theface of falling attendances, occasioned nodoubt by the drought and general apathy, weachieved a near record turn-over and profit. Wehave had crowds of nearly 4000 at the sale inthe past. This year numbers were down to 700approx on the Saturday and about 1000 on theSunday but sales were way up.

The majority of attendees were relatively local(between Liverpool and Picton) whichrepresents an important and new demographicof native plant growers. Although people camefrom as far as Glen Innes and Dubbo, the eventis not being strongly supported by people in theGreater Sydney Region. This is sad as it is agreat day with very interesting and unusualhigh quality plants for sale.

I love the camaraderie and special atmosphereof these events. You can chat to notable peoplelike Merv Hodge, Ray Brown, David Shiells orNeil Marriott from whom so much can be learnt,or the other nurserymen including Phil Keane,Mark Ross, Peter Ollerenshaw, Brian Roach,Pip Gibian, Bernie Kocur, Bruce Higgs, SandraParkinson, Anthony O’Halloran who are ever-ready to give advice or talk about plants. Thesupport of these people is greatly appreciatedby the Study Group. And of course MacArthur,Menai and Sutherland Groups have such aterrific bunch of people and always support theevent with many volunteers, displays andplants they have grown themselves – the truespirit of Australian Plant growers in my opinion.

A number of nurseries no longer support theevent. I find it puzzling, even insulting, that theydo not even bother to answer the invitation toparticipate. This in spite of the fact that all thework is done by volunteers who receive nomoney at all, who are there to raise money forresearch and to support the aims of the studygroup and and Australian plants generally. Iknow where I will spend my nursery dollar infuture and where I definitely will not.

The event was supported by Angus Stewart andDon Burke, both of whom gave their time freelyand addressed the people. Don gave a verycontroversial talk on the Sunday which drewsome criticism. I do not agree with everythinghe says but I sure support his right to say it.

Proposed Itinerary Grevillea Crawl

We will be travelling through western Victoria toSouth Australia collecting Grevillea lavandulacea– several distinct forms including a raresuckering, white flowered form, G. ilicifolia,G. angustiloba ssp angustiloba and sspwirregaensis. We will also be visiting severalSA Study Group members gardens atCoonalpyn and near Murray Bridge. Alsoplanned is a visit to Brenton Tuckers nurseryand extensive gardens near Murray Bridge.

We will be camping out either in the bushor nearby caravan parks. BYO everythingincluding food and drinks for at least 4 days asthere will be little opportunity to shop on theway. There will be a slide evening at Coonalpynso bring any pics etc along to share. This will bea great opportunity for members from Victoria,SA and NSW to get together and share in thefinding of some wonderful plants in beautifulbushland.

Registration is essential – contact Max McDowell,Neil Marriott or Peter Olde.

Preliminary DNA Research

I sampled some Grevillea tissue for DNAextraction and analysis back at the end of July.This material was desiccated with silica gel andI've just now got around to looking at it. I triedthe Qiagen DNeasy plant DNA kit with 20 mg(~1 sq. cm of leaf in total) of young vs. matureleaf vs. some flower buds and vs. some openflowers. I expected the flower buds etc. to givethe best results, but surprising these were verypoor. I got low yields of DNA from leaf samples,totalling usually about 1 microgram. It didn'tseem to make much difference whether theleaves were young or mature. I find that I getabout 20 times this amount of DNA from asimilar amount of orchid leaf! I tried to amplify

James Indstoe

this DNA with ITS PCR and found it amplifiedOK – but with a much weaker product than isnormal with orchid DNA (perhaps again about1/20th as much product). I also get an artifactband of about 250 bp and would need to do agel slice extraction to get a clean product band.To summarise, it appears that I should besuccessful in getting ITS sequence data andwill try a couple of samples to check. I'll alsotry AFLP.

Low DNA yields appear to be the norm forGrevillea. Apart from this and the artifact bandmentioned above, I don't expect too manyproblems – it does make me realise how easyorchids are to analyse by comparison though!

Grevillea diffusa subsp. constableiMakinson

Formal recognition has recently been accordedto one of the loveliest forms in the Grevilleadiffusa complex. In Flora of Australia (2000:499) Bob Makinson has in one step describedthis previously unnamed new taxon andhonoured a prolific collector of Australian plants(Ernest F. Constable 1903-1986). Constablewas the official collector of plants and seeds forthe National Herbarium of New South Walesand the Royal Botanic Gardens, Sydney forover twenty years roughly between 1950-1970and collected at least two New South Walestype specimens in Grevillea.

History: Grevillea diffusa is closely allied withGreviillea sericea and Grevillea linearifolia andhas long been regarded as a complex specieswith many, morphologically different, geographicallydisjunct populations showing close affinity,mainly through inflorescence and flowerstructure. Beadle, Evans & Carolin (Flora of theSydney Region) treated the complex ascomprising one species, G. capitellata, having 5elements. The first element comprisedpopulations in the Bulli Tops region to the southof Sydney. The second was a widespreadpopulation, north of Bulli through to the Menai-Liverpool area. Two elements were noted in theRoyal National Park to Helensburgh area and afifth element was recorded from an area to thesouth of Gosford, around Mt White. Grevilleaevansiana, outside the Sydney region butclearly related, was also accepted as distinct inthe NSW botanical community.

McGillivray(1986 & 1993) realised through hisvaluable work on typification that at least one ofthe five elements, the most widespread, hadpreviously been described as Grevillea diffusaand that this name had priority over G. capitellataunder the rules of botanical nomenclature. Heregarded the five elements of Beadle et al. asbeing really two. He gave formal recognition tothe northern element, describing it and namingit Grevillea diffusa subsp. filipendula. He treatedthe remaining 4 elements as populations of G.diffusa subsp. diffusa, of which G. capitellatawas only a synonym and sunk. The relatedspecies, G. evansiana, was treated as a thirdsubspecies of G. diffusa.

June 2005 Grevillea Study Group No. 71 5

Peter Olde

Olde & Marriott (1994-1995) recognised G.capitellata and G. evansiana as distinct from G.diffusa and reinstated them both as species. G.evansiana is seen as distinguished by itsgenerally broader leaves with granules on theveins. G. capitellata is distinguished by a stoutpeduncle and longer leaves bearing on theirundersurface a shaggy two-state indumentumof long black hairs and often shorter white orcreamy brown hairs. McGillivray (1993)observed these differences but did not considerthe characters sufficiently strong to warrantseparate recognition.

The remaining four elements of G. capitellatasensu Beadle et al. were treated informally asthree elements of G. diffusa by Olde & Marriott,accepting the McGillivray classification of twosubspecies, subsp. diffusa, comprising threeelements, and subsp. filipendula the remainingelement. Grevillea diffusa subsp. diffusa wasseen as being an unresolved complex of threeelements.

Current Taxonomy

In Flora of Australia Vol. 17A (2000) and in therevised edition of the Flora of New South WalesVolume 2 (2002) Bob Makinson has reviewedthe group and clearly made a very close studyof all the elements. Additional useful charactershave been employed to separate the taxa whichcan be clearly accessed from the Key toSpecies. Makinson has accepted both G.capitellata and G. evansiana at specific rank.He has divided G. diffusa into three subspeciesby delimiting a new subspecies, subsp.constablei, from the subsp. diffusa complex.Subsp. diffusa is now more narrowly defined,comprising only the element occurring in theMenai-Liverpool area. Subsp. filipendula McGill.has been retained.

Subsp. constablei comprises two elements sensuBeadle. The distribution of this subspecies iscited as being from Waterfall to Helensburgh,and the Georges River. The Type was collectedc. 2.4 km from Waterfall on E side of line on 2July 1950 by T.M. Whaite. It is distinguished byits taller habit, angular branchlets (eitherglabrous or silky), its longer leaves (4.5–7(–10)cmlong, and its longer, silky peduncles. It wasnamed for Ernest F. Constable, former plantand seed collector for the National Herbariumof New South Wales and Royal BotanicGardens, Sydney.

Page 6: Newsletter No.71

In the area from which the type was collected,subsp. constablei has blackish-maroon flowerscondensed into a tight globose head. Itsinflorescences are most similar to G. evansianaexcept that the leaves do not have conspicuousgranules on the veins and they are much longerand narrower as well. It is an attractive plantmainly found in wet sclerophyl forest that growsup to 2m in height. It often has weepingbranches and is one of the few grevilleas suitedto a shady situation. It has pistils around 6mmlong. Subsp. constablei is unknown in cultivation.

In the eastern part of its distribution (GraysPoint to Audley), subsp. constablei has pistils13–13.5mm long and much looser inflorescencewith dark red flowers. I do propose that thiselement be formally recognised soon, thoughfurther research is required. There is someintergradation along geographic boundarieswhere taxa meet (e.g. track to Lake Eckersley,Heathcote NP).

The following descriptions, using commoncharacters, will assist people to distinguish thevarious related species and subspecies.

At our March meeting Nathan Kirkwood spokeof his research into grafting Proteaceae. Hebegan by outlining the general theoryunderpinning his work, namely that graftedplants perform better on some rootstocks thanothers. Nothing new in this but imagine thatwhen a suitable species rootstock is found aftertesting a range of possible species, anextensive research of the most suitable form ofthis species is then conducted, using clonesfrom different provenances, using hundreds ofseedlings from plants that might be growing indifficult conditions to search out the best andhardiest and therefore the most suitable for amajority of growers. You begin to understandthe scope of Nathan ‘s work. Plants graftedonto the selected rootstock are then testedagainst all kinds of potential damage, diseaseand harm. All this until a suitable rootstock hasbeen decided. Imagine then that you cannotconfine your research to one difficult speciesbut your interest is in all the Proteaceaeincluding all the banksias, grevilleas, hakeas,

Peter Olde

isopogons, petrophiles and waratahs. Nathanbelieves in the need to maximise rootstockhardiness by selecting plants for rootstocksfrom populations that are hardy, or grow indifficult conditions, or conditions that meet theneeds of likely growers. To illustrate this –Nathan spoke about a Banksia serratarootstock selection that he had found growingon clay. Although species might graft readilyone to another, the best compatibility isachieved by selecting from among thesuccessful rootstocks the very best plant for aparticular species. In this respect testing mightbe needed for thousands of plants and only thebest is then clonally reproduced for use with aparticular scion.

Being a person somewhat challenged forincome Nathan has made use of recycling andinnovation. For tubes, Nathan uses 21mm whitepoly pipe cut to c. 15cm lengths. Poly pipe ischeap, strong and can be reused endlessly. A

piece of florist foam is placed in the bottom.This is first stamped from an oasis foam blockby another piece of sharpened 21mm pipe sothat size matches. The tubes do not stand bythemselves and need to be packed into a trayfor mutual support. Bakers bread trays are idealand hold a large number. Potting mix is thenintroduced to the tube and the seedling sown orpotted up. Nathan ‘s potting mix comprises acombination of commercial low phosphoruspotting mix, polystyrene foam and expandedclay (used in hydroponics). This is a very openmix. The seedlings are then allowed to grow onready for use as rootstocks or scions.

Grafting is done in a converted garden shed.The walls are insulated with old polystyrenepacking case sides. Nathan has a developed alow humidity environment for his grafts, most ofwhich are executed in late winter to spring. Hefinds late summer is too humid and contributesto too many losses from fungal/bacterialattacks. A dehumidifier stands in the middle ofthe shed and an air conditioner is mounted inthe side. A temperature lower than 20 deg C isnecessary but on average he thinks that 17–18deg is ideal. Circulating fans and thermometercomplete the equipment. Scions are firstcleaned by dunking in a solution of dettol andlisterine cut 70/30 with water. They dry with aslight powder on the surface which continues toprotect them from fungi and bacterial rots.

Cotyledon grafts are used. Using a Wilshiredouble-sided razor blade (difficult to buynowadays) scions are trimmed to a V below thecotyledon if using a seedling (banksia), oranywhere on the stem if using a cutting. Young,semi-hard wood is preferred for scions. The topis first cut off, above the cotyledon for scionseedlings, and trimmed to a V. Nathan hasdevised his own unique system for achievingthis. A cut 0.5–1cm deep is then made down themiddle of the rootstock. The two pieces (scionand rootstock) are then attached by insertingthe scion into the cut rootstock. The graft unionis wrapped with nescofilm and sprayed withSteriprune. (Pressure packs can be purchasedin garden outlets). This is a tar-like substancewhich seals over the graft. If leaves have beentrimmed or leaves taken off the scion, this areais also treated with Steriprune. At present Nathanapplies the steriliser by hand and brush which

is very tedious. The tubed graft is then placedon a shelf over which grow lights have beeninstalled – at a height approximately 30cm abovethe top of the grafts Bright NEC globes are justas good, Nathan claims. They have a better andlonger life and are much cheaper. The graftshould take in less than 3 weeks if it is going tosucceed. There are three shelves one abovethe other along one side of the shed. No naturallight is used, no mist, no humidity. Goodsuccess has been achieved using this method.

Interstocks are also being trialled for difficultspecies, for which no outstanding singlerootstock can be found.

Nathan is also developing an interest in planthybridisation and breeding, which topic he tooka few moments to outline. He then proceededto show a few of the developed hybrids growingin his garden. These are recorded here forhistorical reasons. Grevillea ‘Robyn Gordon ‘was induced to set seed by starving the plantand treating it very harshly.

Western Australia Grevillea researchtrip August – September 2003

Part 2 – continued from newsletter 70

After the exultation of finally finding Grevilleamerceri ms we were due for a let down, andwe had it with the next elusive Grevillea we hadto search for on our itinerary. Yet anothernew species unearthed while sorting throughthe herbarium specimens of the Manglesiagroup! The plant in question was collectedanonymously at Kojoneerup – on the north sideof the valley. Kojoneerup is a location on thesouthern edge of the Stirling Ranges. Withoutany more accurate collection data itsrediscovery would be rather chancy to say theleast. However when we arrived at the propertyknown today as Kojoneerup we were dismayedto find that nearly all the countryside had beencleared. We spent the day searching along thesouthern edge of the National Park as well asscouring every roadside and remnant bushlandpatch in the area but to no avail. Hopefully thisnew species will still occur somewhere in thedistrict awaiting discovery in the future!Readers are encouraged to keep a sharp eyeout for ANY white flowered grevillea they mayfind growing in the district.

The Gondwana Link Project

Wendy and I work for the Trust for Nature andGreening Australia in Victoria, protecting andrestoring remnant bushland. As a result KeithBradby had promised to take us to see thelatest property acquisition and restorationworks linked with the amazingly ambitious andfarsighted Gondwana Link project. GondwanaLink aims to reconnect through propertypurchase, conservation covenants and restorationworks the biological links that once connectedthe Fitzgerald River National Park and thesouth coast with the large blocks of crown landinland from Jerramungup and continuing intothe deserts of inland Australia!

Their latest purchase through the AustralianBush Heritage Fund was a beautiful large areaof mallee and woodland north-east ofJerramungup. This is an amazing area thatshould never have been opened up foragriculture – it is dotted with spectacular red andorange spongelite breakaways, deep sandyvalleys, granite outcrops, rocky streams andheavy clay mallee patches. Fortunately much of

it remains uncleared and as a result is beingprogressively purchased and the cleared areasrevegetated. On the property we visited JackMercer had just completed the direct seeding ofseveral hundred hectares with indigenous seed– so diverse is the area that the seed mixcontained over 30 species of Eucalypt alone!!

After a superb picnic lunch under a grove ofSheokes we headed off for a wander throughthe property, eyes peeled for new grevilleas!We didn’t find any but there is no doubt that whenthorough flora surveys are carried outnumerous new and rare plants of all genera willbe found. The property protects extensiveareas of Sheoke and Blackbutt woodland –communities that have been all but wiped outelsewhere for agriculture. As result we found lotsof beautiful small herbaceous and ephemeralspecies several of which are quite rare. On asoon to be purchased nearby spongelitebreakaway we found masses of unusual shrubsincluding beautiful deeply divided leaved formsof Grevillea pectinata, fiery red flowered formsof Grevillea huegelii, a most unusual dense lowpale yellow flowered acacia and numerousattractive low mallees and banksias.

A very rare hakea

Continuing east we met up with a friend inRavensthorpe who is a botanical consultant likemyself. On a recent survey to the east ofRavensthorpe for a proposed limestone mine,Tim Nolan had discovered a lone specimen ofthe extremely rare Hakea acuminata. This is aspecies that is unknown in cultivation and onethat I was keen to find for Paul Kennedy andothers in the Hakea Study Group. After aninteresting walk through a wonderful area oflow to tall heathland with scattered eucalypts,we came upon the big old specimen of Hakeaacuminata – it had finished flowering but wasstill a most attractive plant with large, broadgrey-green patterned leaves with a tapering(acuminate) point, contrasting with the brightgreen immature fruits. Half of the plant hadbeen broken by the fencing contractor so werescued a number of fruits from this section.The remaining plant is in a precarious position ifthe proposed mine proceeds – I hope it doesn’t asthe area is rich in beautiful and unusual shrubsincluding numerous dryandra, verticordia andbanksia. Who says that the West’s bushland isnow secure!!

The “Lake King Grevillea”

Another new grevillea that Peter and I“discovered” whilst checking through thespecimens at Perth was a large flowered plantcollected near Lake King and identified asGrevillea sp aff hookeriana. We had searchedin vain for the species along the Biddy CammRd the year before but there did not appear tobe any remnant bushland near the siterecorded for the collection.

Following our success with the discovery ofGrevillea merceri ms, Wendy and I decided toinstead try and find the property owner onwhose land the specimen was collected.

After much detective work we eventuallycontacted a Mrs Nell Silver – amazingly shecould still remember the unusual grevillea andso we headed out to her farm to see her. Nellturned out to be a wonderful lady who has adeep love of her local flora and despite hercollecting the specimen many years ago wasable to take us straight to the plant. It turned outto a single large old specimen along a fencelinewhere it will be destroyed as soon as the fenceis replaced! Examination of the plant revealed itto possibly be a most beautiful hybrid, probablybetween Grevillea excelsior and Grevilleacagiana both of which occurred in the area. Ithad deeply divided fine green foliage and large,very showy orange flowers set amongst theouter foliage.

Although the original collection stated that theplant was common at the site, only the oneplant could be found despite a thorough searchof the bushland remnants in the area. Sadly,cutting material sent back to Mt Annan BotanicGardens and to Merv Hodge failed to bepropagated. This is a pity as this beautifulgrevillea which Nell is keen to call the “LakeKing Grevillea” is gravely threatened and wouldbe a spectacular plant under cultivation.

East to Esperance

Leaving Lake King we intended to head downto Esperance via the Cascades Rd – put inillegally by local farmers as a shortcut througha magnificent wilderness area to the east ofLake King. Unfortunately there had recentlybeen heavy rains and the road was damagedand only open to 4WD’s. Instead we headeddown the beautiful Nindilbillup Rd. This is oneof the most beautiful roads in the region, with a

June 2005 Grevillea Study Group No. 71 10

wealth of interesting plants and few of theweeds and roadside vandalism by councilworkers that have destroyed most of the West’sfloral heritage.

We had not gone far when we came upon adistinct form of Grevillea patentiloba that clearlywarrants recognition as a new subspecies. Ithad foliage that is uniformly intermediatebetween G. patentiloba ssp patentiloba and G.patentiloba ssp platypoda and the plants madenice rounded small shrubs less than a metrehigh. A little further on we came upon awonderful population of Grevillea pectinatagrowing in white sandy clay – interestingly thisgrevillea may also warrant recognition as a newsubspecies. The plants had most attractiveentire leaves and were observed to bereproducing strongly by suckers as well as byseed in a section of the population where a firehad recently gone through. They were growingin damp mallee/melaleuca woodland withGrevillea decipiens, a species that alwaysfavours these wet, clayey areas. Specimenswere collected before we continued on to theRavensthorpe-Esperance Rd.

Continuing south along this wonderful road, wecame to Moolyal Creek – here we found awealth of plants growing in tall mallee, includinga form of Grevillea anethifolia, an unusual formof Grevillea acuaria, the new subspeciesGrevillea patentiloba again, Grevillea oligantha,Grevillea teretifolia, as well as beautifulspecimens of Banksia media, Hakea lissocarphaand Hakea corymbosa.

Stopping for a cuppa in a sandy Banksiaspeciosa scrub area not far along the highwaywe found attractive low shrubs of Grevilleaconcinna ssp lemanniana growing to little morethan 20 cm high with massed small redtoothbrush flowers. At the same site we alsofound the beautiful Conostylis vaginata with itscurious stilted growth habit and showy orange-yellow flowers.

East to Cape Arid National Park

After restocking supplies in Esperance weheaded out east to the magnificent wildernessof Cape Arid National Park -this is a vast areawith few tracks and even fewer tourists. Thearea is dominated by extensive areas ofheathland, interspersed with patches of tallermallee, granite outcrops, massive granite hills,dense coastal scrubs and swampy tracts. Themain camping area is at Thomas River wherethere are a limited number of small clearings inthe coastal scrub where you can squeeze inyour tent or van. We got a site overlooking thespectacular white sandy bay with the mostazure blue water you could ever see. To makethe picture complete there was even a SouthernRight Whale with her baby slowly gliding backand forth in the shallows for several days!

Way back in the early days of settlement ofWestern Australia a plant was collected atThomas River by George Maxwell and sent toBaron Von Mueller in Melbourne. StrangelyMueller never described this as a new species.Our research showed that it clearly warrantsrecognition as a new taxon and it will bedescribed in our upcoming paper. We hadhoped to relocate the species before wepublished and so Wendy and I set aside fourdays to track it down. However despite walkingfor kilometres along what seemed every hill,outcrop, headland and heathland we failed torelocate this elusive grevillea. We consoledourselves that it MUST be in an isolatedlocation as it has never been recollected in the150 years since it was first discovered!!

However we saw some magnificent sceneryand plants in the process including thewidespread Grevillea concinna ssp lemanniana,G. nudiflora and G. pauciflora ssp psilophylla.The last is a very free flowering and showy

grevillea that really should be raised to the rankof species. We found it growing in wet sandysoils on the edges of swamps where it made afiery red flowered display on shrubs up to 1.6 mhigh. Unfortunately this grevillea is still notknown in cultivation.

Other highlights were the distinct low andextremely fine leafed form of Grevillea plurijugawith prostrate flowering stems radiating out fromthe bush-this is yet another taxon that clearlywarrants recognition as a new subspecies.Sadly with Western Australia’s terrible lack offunding for their herbarium, there is no-onedoing this sort of research, and there is just toomuch for Peter and I to do – we don’t even getpaid for the huge amount of work we do.Fortunately the Grevillea Study Group hasassisted us with our travel expenses for thelast few trips.

Another amazing grevillea that we found was adistinct form of Grevillea baxteri possiblywarranting recognition as a new subspecies.Instead of the normal large spreading habit ofthis species as it occurs to the north and east ofEsperance, the form we found way out furthereast in Cape Arid National Park at locationssuch as at the Diamonds was extremely tall andnarrow with no strong lateral branching at all.As a result the plants stood well above thesurrounding plains and as I watched flocks ofhoneyeaters travelling through would alight onthem, feed briefly on their showy orange-redflowers before continuing on their way. Clearlythis tall habit had evolved as a strategy toencourage cross-pollination by honeyeaters ina region where the typical bushy habit wouldnot stand out as a beacon for birds that are notpermanent residents but are always justmigrating through. This may possibly beexplained by the very dry climate and lack ofwater out in this region compared to the morefavourable conditions back around Esperance.It is quite fascinating to see evolution in actionsuch as this – something that desk botanistssitting in their comfortable armchairs never pickup from just looking at dried specimens.

On the road home

The highway from Esperance to Norsemangoes through some most interesting vegetationchanges, quickly leaving the relatively reliablecoastal zone, then into the sub-coastal semi-aridand finally into the dry goldfields region. As aresult there are many interesting plants to befound as you travel along this road. Grevilleabaxteri is common in the coastal sands in tall scrubsfor about 30 km north of Esperance, growing asa large spreading shrub to around 3 x 4m.

Leaving the coastal sands the highway travelsthrough a region of heavy white sandy clay.This is dominated by stands of tall mallees witha rich mixed understorey dominated bymelaleucas. Here we found the beautifulGrevillea superba with its strongly erect habitand flower racemes on long canes above thefoliage. Also common here were Grevilleahuegelii – comb leaf form, Grevillea oligantha –narrow leaf form, Grevillea pectinata – entireleaf form and in a nearby gravel pit we found afine-leaved shrubby form of Grevillea nudiflorawith deep red flowers.

Just north of Grass Patch we found Grevilleasuperba and Grevillea plurijuga. G. plurijuga canbe readily separated from G. superba by itsstrongly arching, rounded habit, floweringracemes rarely erect above the foliage but withsome always arching down from the bush to runalong the ground or on old wood within thebush. Finding the two species growing togethersurely puts paid to the argument that they arethe same species!

Soon the vegetation changed as we entered theGoldfields region with its dry stony soils anddistinct woodlands dominated by the beautifulSalmon Gum Eucalyptus salmonophloia, aswell as a multitude of other eucalypts. Theunderstorey here is generally sparse, withscattered shrubs in some areas and with a morecontinuous cover in more open or gravely sites.

Heading east from Norseman we had just onemore white flowered grevillea to find at MtNorcott. Careful searching located a bush trackheading south-west to this obscure mountain28 km east of Norseman. Near the intersectionwith the highway we found a beautiful denserounded form of Grevillea acuaria with rigidpatent leaves and wholly red flowers. In the samearea we found Eremophila interstans, E scopariaand an attractive white flowered olearia.

June 2005 Grevillea Study Group No. 71 12

As we neared Mt Norcott we came upon asudden change in soils and vegetation. Theappearance of spinifex grass made us keep oureyes out for grevilleas and sure enough, wealmost immediatly found our first Grevilleaanethifolia in massed full flower. We continuedon and arriving at the base of the small butsteep “mountain” we came upon a whole field ofthis beautifully perfumed grevillea. Clamberingup the rocky slope we found numerous showyshrubs most notable of which was a richburgundy Hop Bush Dodonaea sp. We collectedspecimens of the grevillea and set up camp,ready for the long drive back east acrossthe Nullarbor.

Our trip was almost at an end – we had foundmany of the grevilleas we had searched for,although several still await our rediscovery. Butthe West is a vast state still hiding a multitudeof new plants – it will take many decades beforewe come anywhere near the recording of all ofits species! In concluding, I would like to thankthe Grevillea Study Group for their ongoingassistance with our travelling expenses.

Grevillea ‘Misty Red’

Date: 12/01/2004

Anyone looking for something extra specialthis Christmas, would be wise to look forGrevillea ‘Misty Red’: a deep pink, nearlyred, exotic flower.

Grevillea is a close relative of Banksia andProtea. All of the varieties have feathery, gray-green foliage, which implies the plant’s othername of ‘silver oak’. Grevillea ‘Misty Red’ is acrossbred hybrid of G. banksii, which has alreadybeen the source of many other attractivehybrids including the yellowish-pink ‘Misty Pink’.

It is one of the most popular domestic shrubs inAustralia. This is not really surprising, sinceeach exotic bloom is uniquely shaped andincredibly colorful. In addition, many Grevilleavarieties also attract birds that feed on nectar.

Although the actual flowers of Grevillea ‘MistyRed’ (vbn code 22220) are fairly small, they areformed in clusters. The dark pink, nearly redinflorescence looks a little like a brush andmakes a decorative addition to Christmasarrangements and bouquets. The sturdy stems,which are on average 24 to 28 inches long,have an excellent vase life of two weeks.

Israeli growers have supplied them to the Dutchflower and plant auctions since October 2003.During that year a total of 79,000 stems weresold and this year already 255,000 stems havebeen sold. The product is available fromSeptember through April.

Family

Grevillea is a member of the Proteaceae family.

Top 8 cultivars

‘Spiderman’ ‘Ivanhoe Bronze’ ‘Misty Red’ ‘Yovel’ asplenifolia ‘Misty Pink’ ‘Honey Gem’ ‘Cal Gem’

Tips for care

Diagonally cut the stems and place them inwarm water containing special cut flower foodfor shrubs.

These cut flowers should not be exposed totemperatures lower than 36 to 50° F. The floweris sensitive to cold and black discoloration canoccur as a result of cold exposure.

Explanation of name

This cut flower was named after Ch. Fr.Greville, one of the founding fathers of theRoyal Horticultural Society in London. He wasresponsible for introducing a number of exoticplants to England.

Most important colors

Yellow/orange and pink/red are the mostimportant shades of color.

Additional information

Currently work is underway on the developmentof a white as well as a champagne coloredvariety. A longer vase life and new colors arekey to the future development of this plant.

Grevillea nivea – sort of!

There was a time when I shunned graftedplants. It seemed like cheating to me.

Additionally, in operating a very small nativeplant nursery I was always conscious ofpotentially having to say that a particular plantin my garden wasn’t propagated by mebecause it was grafted; so I didn’t grow graftedones. Since common sense prevailed however,grafted plants and particularly Grevilleas havebeen given a proud home. Having just drooledover my Grevillea nivea (as I thought it was)while taking the included photograph, I’mfortified in this belated decision to dabble withgrafted plants. What a Bobby Dazzler this oneis! In deciding to write about it, I rushed toconsult ‘The Grevillea Book’, that marvellous 3volume compendium of all things Grevillea; so Ithought. No Grevillea nivea! I checked the labelthat was on the plant when I bought it about ayear ago at Mt.Annan. Grevillea Scarlet King!Neil Marriott, a co-author of ‘The GrevilleaBook’ recommended the plant to me and said itwas actually Grevillea nivea. Would I doubt him?

Brian Roach

A quick consultation with the other authorrevealed that it still awaits official descriptionunder that name having appeared in their bookunder Grevillea tetragonoloba – form b. It hailsfrom the south-western corner of W.A. nearBremer Bay.

In the meantime, if you want to get one, look forGrevillea Scarlet King. It’s a wonderful plantwith the most vibrant red I’ve ever seen in aflower colour. It contrasts spectacularly with thedeeply divided grey foliage. It seems to haveflowers most of the year. I’m told it will grow toaround 2.5m by about the same width if leftunpruned and according to the label it has‘Extreme tolerance to wet and dry soils’. Whatmore could you want?

Rosemary Grevillea –The shrub wandering away from home

This is quite an attractive shrub and is sold inmany nurseries across Australia. Rosemarygrevillea (Grevillea rosmarinifolia) is native toVictoria and a small part of New South Wales,where it occurs at a moderate altitude, on rockysites or in areas with shallow soils.

The book, Native Trees and Shrubs of South-Eastern Australia by Leon Costermans,describes “stiff, narrow and needle-pointed”leaves that are “green above and palerbeneath, (with) margins usually rolled under.”

In South Australia, this species is usuallybetween one and two metres in height and isvery dense. It is often grown as a hedge typeplant, but many Bushcarers are now finding thisplant occurring on their sites – as a weed.

Andrew Allanson

Yes – it is a weed!For many people, a plant that is native toAustralia being regarded as a weed is difficult tounderstand. The fact is, this species does not occurnaturally in South Australia. The introducedrosemary grevillea is cross breeding with the locallavender grevillea and degrading its geneticviability. Hence, conservationists are very concernedthat the lavender grevillea will eventuallybecome locally extinct.

The removal of rosemary grevillea is via theusual cut and swab method. Always work fromthe best bush outwards.

Check before removing itBefore doing any work on this weed, make sure thatit isn’t the local lavender grevillea. Always have theplant identified by an expert and if necessarytake a cutting of it and use this to compare withthe local species of lavender grevillea.

Is there still an interest in havinga seed bank?

Most of the seed in the seed bank is nowthree years old at least and some dates backto the early nineties. An injection of new seedfrom as many members as possible isneeded. Interest in the seed bank has beenvery low – only two enquiries in the lasttwelve months. If members want the seedbank to continue some new seed should bepurchased but what do members want?
