Nodal anatomical study of certain members of the Rutaceae
The vascular organization of the node in 12 genera has been investigated. The leaves are unifoliate in Atalantia, Citrus and Paramignya, 3-5 foliate in Aegle, Luvunga, Toddalia and Glycosmis, decompounds in Ruta and imparipinnately compound in other taxa. These are alternate or opposite and exstipulate. The foliar nodes are trilacunar, three-trace in the majority of the plants. It is unilacunar in Atalantia racemosa, Citrus jambhiri, C. maxima and Glycosmis pentaphylla. The results are discussed with respect to the evolutionary conception of node.

ABSTRACT: The vascular organization of the node in 12 genera has been investigated. The leaves are unifoliate in Atalantia, Citrus and Paramignya, 3-5 foliate in Aegle, Luvunga, Toddalia and Glycosmis, decompounds in Ruta and imparipinnately compound in other taxa. These are alternate or opposite and exstipulate. The foliar nodes are trilacunar, three-trace in the majority of the plants. It is unilacunar in Atalantia racemosa, Citrus jambhiri, C. maxima and Glycosmis pentaphylla. The results are discussed with respect to the evolutionary conception of node.

INTRODUCTION
The Rutaceae family includes about 160 genera
and 1,900 species that are widely distributed in tropical
and temperate regions around the world, but they are
especially abundant in Australia and South Africa
(Groppo et al., 2008; Cronquist, 1988). While studying
the nodal organization in the angiosperms, Sinnott
(1914) have reported the trilacunar and unilacunar nodal
structure in Rutaceae. Hayward and Long (1942) have
also made observations on variations in the cotyledonary
nodes in Valencia orange. Since the nodal vasculature in
the family has received little attention, it warrants a
detailed study. Consequently the present study were
undertaken to study the nodal organization of
16 species distributed in 12 genera.
MATERIAL AND METHODS
The plant materials of Atalantia monophylla DC,
Toddalia asiatica Lamk. and Glycosmis mauritiana
(Lam.) Tanaka were collected from Lalbagh Botanical
Garden, Bangalore, Citrus jambhiri Lush and
Citrus maxima Merr. were obtained from Parbhani where
as Luvunga eleutherandra Dalz., Clausena dentata
(Willd) Roem and Fagara budrunga Roxb. were
collected from Ratnagiri. Glycosmis pentaphylla (Retz)
DC. was collected from Kalakadu, Tamilnadu.
Paramignya monophylla Wight was collected from
Kegadi forest Nandore while Atalantia racemosa Wight.
Ex. Hook was collected from Gandhinagar, Matheran.
Ruta graveolens L. and Aegle marmelos (L.) Corr. were
