pedicelled. Stigma conical or shortly beaked, hardly or not exserted. Follicles 

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

 gascar, Malay Islds. and China. 



S. ZJXaing-ayi, Hook. f. ; quite glabrous, leaves broadly ovate-cordate 

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

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



MALACCA; Maingay (Kew distrib. 1112). 



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

 petiole -1 in. Peduncle 2-3 in., few-fld. ; pedicels l-l in. ; bracts subulate. 

 Sepals f in., acuminate, coriaceous. Corolla-tube 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. 



35. LYGIS1VEA, Hook.f. Gen. Nov. 



A puberulous slender much diffusely branched twining shrub. Leaves 

 small, opposite, lanceolate. Flowers small, in numerous axillary umbellifbrm 

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

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

 the upper half sharply doubled down inwards (buds hence truncate). Corona 

 of minute obtuse anpressed teeth at the back of the anthers. Column minute, 

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

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

 puscle. Stigma included. 



L. ang-ustifolia, Hook. f. Ic. Plant, t. 1423. Marsdenia angustifolia, 

 Wight. Contrib. 40 ; Wall. Cat. 8172 ; Dene, in DC. Prodr. viii. 614. 



BIRMA ; 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 

 p-| in., very slender, pedicels \ 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 aestivation, rendering the bud truncate. 



36. TYX.OPHORA, 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. Stigma disciform, 

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

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



The minute anthers (larger in T. Iphisia), forming a small ring 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 

 xact 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.
