Leaves 6-8 by 3-4 in,, usually acute; petiole 1 in. Male flowers very small, 

 pedicels ^-\ in. ; female flowers including the ovary in. Ovary early becoming 1- 

 celled by the separation of the 3 fleshy placentas which only at first meet in its centre. 

 Seeds much compressed, hardly ^ in. thick. 



DOUBTFUL SPECIES. 



?ZANONIA; leaves 5 by 2 in. narrow-oblong rounded at the base, tendrils lateral. 



CHITTAGONG / H. /. $ T. The example contains neither flowers nor fruit, but has 

 all the appearance of Zanonia to which genus the collectors referred it in the field. 

 The only other species of the genus (collected by Beccari in Borneo) has the seed 

 (including the wings) 6 in. broad curved lunate. 



29. AX.SOIKITRA, JBth. $ Hk.f. 



Large climbers; tendrils simple or 2-fid. Leaves with 3 oblong entire 

 leaflets. Flower* small, dioecious, white, in compound paoicles, with filiform 

 branches. MALE : calyx rotate, 5-partite, segments oblong, acute ; corolla 

 rotate, 5-partite, segments obtuse ; stamens 5, filaments short, near together at 

 the base ; anthers small, oblong, straight, 1-celled. FEMALE : calyx and corolla 

 as in the male ; ovary elongate-clavate, 1-celled ; styles 3-4, conical, with 

 semi-lunate stigmas ; ovules very many, pendulous ; placentas 3, thick, vertical, 

 parietal. Capsule large, elongate-clavate, truncate and 3-valved at the apex. 

 Seeds very many, compressed, vertical, in six rows, much corrugated, incised or 

 horned on the margin with a terminal membranous wing longer than the seed 

 or 0. DISTEIB. Species 3-5, extending from Nipal through Malaya to North 

 Australia.

Leaflets 2 by If in., obtuse ; petiolule scarcely \ in. Seeds black, not much com- 

 pressed, narrowed nearly to a point at the base with 2 flat thin (not 2-fid) curved 

 horns at the apex, between which rises the wing. 



2. A. clavig-era, Hook. f. in Gen. PL i. 840 ; leaves herbaceous, fruit

 flat faces. Zanonia clavigera, Wall. PL As. Rar. ii. p. 28, partly ? ; Cat. 3725.

 3000-4000 ft.; H. f. $ T. SILHET ; Wallich. TENASSEBIM ; Heifer (Kew Distrib. 

 No. 2520). 



Leaflets 3 by 1 J'jn., acute ; petiolule often exceeding in. Seeds yellowish-white, 

 much flattened, with several deep triangular spinose teeth at the apex, teeth of 2 

 lamellae, between which the wing is inserted, split in the plane of complanation of the 

 fruit, and the wing springing from these narrow splits. Wallich's description of the 

 seed of Z. clavigera is incorrect and appears to be taken from that of Z. indica y 

 which grows in the same locality.
