pedioelled. Stigma conical or shortly beaked, hardly or not exserted. FoUiclea 

 very thick, obtuse or acuminate. Seeds comose. — Disteib. Species 14, Mada-

S. IMIaing^ayl, Hook. f. ; quite glabrous, leaves broadly ovate-cordate 

 acuminate, cymes on long stout peduncles, sepals large lanceolate acuminate, 

 corolla-tube 1 in., lohes lanceolate acuminate, anther-tips long, coronal 

 scales 0. 



Malacca; Maingay (Kew distrib. 1112). 



Sranches stout. Leaves 4-6 by 2-3 in., basal sinus aeute, nerves about 8 pairs ; 

 ipetiole i-1 in. Peduncle 2-3- in., few-fld. ; pedicels 1-1|^ in. ; bracts subulate. 

 S^ais f in., acuminate, coriaceous. CoroUa-tiibe with 5 hairy ridges at the base 

 within, lobes about equalling the tube. Column ^ the length of the tube. Anther- 

 tips as long as the rest of the column, obtuse. Stigma capitate, 



36. ZiVGXSnXA, H6ok.f. Gen. Nov. 



A puberulous slender much diffusely branched twining shrub. Leaves 

 .small, opposite, lajiceolate. Flowers small, in numerous axiUary umbelliform 

 •cymes. Sepals ovate, eglandular. Corolla salver-shaped, tube very short, lobes 

 long, linear, waved, obtuse, the lobes overlapping to the right below the middle, 

 i;he upper half sharply doubled down inwards (buds hence truncate). Corona 

 of mmute obtuse appressed teeth at the back of the anthers. Column minute, 

 fleshy, low, cylindric; anthers very short, with small rounded membranous 

 tips ; pollen-masses cylindric, clavate, waiy, erect, subsessile on the long cor- 

 puscle. Stigma included.

BrEMA ; hills near Prome, Wallich. 



Leaves 1—2 by |-| in., acute, glabrous when mature, base rounded, triple nerved 

 at the base ; petiole very short. Cymes in all the upper axils, many-fld. ; peduncle 

 |-5 in., very slender, pedicels -j in. Sepals obtuse, pubescent. Corolla glabrous, ^ 

 in. diam. — A very curious plant, the only Indian AsClepiad one known to me with the 

 corolla-lobes doubled down inwards in jestivation, rendering the bud truncate. 



36. TYIiOPHORA, Br. 



Twining, rarely erect, herbs or undershrubs. Cymes umbelliform or race- 

 mose ; flowers small or minute. Sepals ovate or lanceolate. Corolla rotate ; 

 lobes broad, slightly overlapping to the right. Coronal processes fleshy, adnate 

 to the very short column. Anthers very small with an inflexed tip ; pollen- 

 masses one in each cell, minute, globose or ovoid, waxy, erect or ascending 

 rarely transverse or pendulous from the 'ascending pedicel. /SSa^jfrna disciform, 

 5-gonal, included. Follicles acuminate, smooth. Seeds ovoid, flat, winged, 

 comose. — Disteib. Species about 40 ; Asiatic, African, Australian and Oceanic. 



The minute anthers (larger in T. Iphisia), forming a small ling round the disci- 

 form stigma, which is more or less overlapped by the short anther-tips, and the 

 adnate usually gibbous or globose coronal processes are the best characters for this 

 genus. The position of the pollen-masses, ascending, horizontal, or pendulous, can- 

 not be depended upon, and is most difficult to ascertain in dried specimens ; as is the 

 ■exact form of the fleshy coronal processes. 



* Stem short, erect or suberect, 1-2 ft. (perhaps longer and twining in T. 

 Iphisia), sometimes twining at the tips.
