by the time the raeemed one is in blossom. The corolla is slightly oblique ; in 

 T. dubia besides the normal large male flowers much smaller imperfect ones are often 

 found.

 acute undivided, male racemes with prominent bracts, petals f in. golden 

 yellow. Naud, in Ann. Sc. Nat. ser. 4, xii. 150, t. 10 ; Bot. Mag. t. 5469 ; Kurz

Plain of EAST BENGAL common, ascending to 8000 ft. in the hills. The female 

 plant is rare and has never been collected in the plains. PEGU ; Kurz. DISTRIB. 

 Malaya, China. 



A large climber. Leaves 4 by 2 in., denticulate, not at all angular, usually 

 villous beneath sometimes nearly glabrous ; petiole 1^ in. Tendrils simple in all the 

 wild examples, but in Naudin's strong cultivated plants bifid. Male racemes 2-3 in., 

 flowers approximated, bracts serrate or incise-serrate ; calyx-teeth very narrow; 

 filaments minutely hairy. Female peduncle 2-3 in., more or less hairy ; young 

 ovary densely woolly. Fruit 1| by 2 i n ., glabrous, obtuse at both ends. Seeds 

 scarcely \ in. There is an admirable picture of this plant amongst Roxburgh's 

 drawings. 



2. T. Hookeri, C. B. Clarke ; leaves deeply cordate-ovate acute entire 

 and tripartite with lanceolate segments, male racemes without bracts, petals 

 less than in.

A large climber ; tendrils simple. Leaves polymorphous, acute, resembling alto- 

 gether those of T. dubia, but generally less hairy and thinner, or tripartite, with seg- 

 ments 4 by If in., the two lateral lobes very cordate and auricled on the outer base ; 

 petiolules hardly in. ; petiole 2 in. The female flower in Griffith's example resembles 

 that of T. dubia but is smaller though the petals are slightly more than in ; 

 peduncle about I in. Male racemes 1 in., slender; flowers pedicelled, scattered, 

 yellow; petals scarcely in. ; these small flowers probably correspond to the small 

 imperfect males often found in T. dubia ; if so the large perfect males of T. Hookeri 

 are as yet unknown. Fruit (and seeds) altogether like those of T. dubia, but rather 

 smaller, l^ in. The ebracteate male raceme of this with pedicels in. is exceedingly 

 unlike that of T. dubia : but in all other points they appear congeneric, and the 

 Jiabit is the same. 



24. EDO A HI A, C. B. Clarke. 



A large scandent herb ; tendrils 2-fid. Leaves petioled, entire, ovate, acute, 

 deeply cordate, more or less pubescent. Flowers large, dioscious, yellow. Male 

 peduncles paired, one 1-flowered caducous, the other raeemed ; bracts or in- 

 conspicuous ; female peduncle elongate, 1-flowered. MALE : calyx-tube elon- 

 .gate, funnel-shaped, teeth 5, subulate ; corolla deeply 5-partite, with obovate 

 acute segments ; stamens 3, included in the calyx-tube ; filaments exceedingly 

 short ; anthers connate into a cylindric tube, one 1-celled, two 2-celled ; cells 

 straight, linear-oblong, connective not appendaged. FEMALE : calyx and 

 corolla as in the male ; ovary narrow-obovoid, 3-celled ; style long, stigmas 3, 

 oblong, 2-fid ; ovules 1-3 superimposed in each cell, horizontal or subpendu- 

 lous. Capsule large, broadly fusiform, trigonous, 3-celled, fibrous, dry, 3 

 valved, valves dehiscing downwards and leaving the trigonous central axis. 

 Seeds 1-3 in each cell, pendulous, compressed, subquadrate, large, corrugate or 

 somewhat 3-lobed at the lower end and faces when dry.
