Twining herbs, tendrils usually simple or 2-fid. Leaves petioled, 5-angular, 

 nearly entire or deeply Iplied. Floivers white (or yellow ?), somewhat large ; 

 monoecious at least, sometimes : male peduncles in fully developed plants 2 

 from each axil, the earlier 1 -flowered, the later longer racemose, either often 

 suppressed; bracts in the 'racemes persistent, large lanceolate incised*or small : 

 females 1-flowered usually in separate axils. MALE: calyx-tube long, contracted 

 near the mouth, limb of 5 lanceolate segments ; petals 5, not fimbriate on 

 margin ; stamens 3 ; anthers included, connate, elongate, 1-celled, 2-celled, 

 cells conduplicate ; rudiments of the ovary 1. or 3, small, linear. FEMALE : calyx 

 and corolla as in the male ; ovary oblong ; style long, stigmas 3 short linear ; 

 ovules horizontal, many ; placentas 3, long, vertical. Fruit ovate-oblong, acute 

 at both ends. Seeds many or few, ellipsoid, compressed, margined, nearly 

 smooth. DISTRIB. Species 5 ; in India, China and Malaya.

Stems slender, 5-angular, more or less scabrous-hairy. Leaves 2-3 in. diam., sca- 

 brous on both surfaces ; tendrils simple or 2-fid. Male racemed peduncle sometimes 

 6-8 in., usually shorter ; bracts f in., incise-serrate, lobes often again incised. Calyx-

2. Cr. quinquelobum, Miq. Fl. Ind. Sat. i. pt. i. 681 ; leaves subor-

 oblong serrate. Scotanthus Porteanus, Naud. in Ann. Sc. Nat. ser. 5 ; v. 25.

Agrees very closely with the last species : the segments of the leaves *re here 

 narrow, subsinuate, 3-fid or pinnatifid, but graduate towards the half-lobed form of 

 G. cochinchinensis. Kurz's G. heterophyllum agrees as described with the present 

 species ; it is perhaps a specimen with poorly developed male racemes. Kurz says 

 the flower is white, and quotes Bryonia heterophylla, Wall. Cat. 671 1, which obscures 

 the whole matter, for that plant is Bryonia palmata, "Wall, (now Cephalandrd) while 

 B. heterophylla, "Wall. No. 6704 (and of which there is a solitary sheet) differs al- 

 together from Mr. Kurz' description and is a Cerasiocarpum.
