90. ASCLEPIDACEJE. [22. Ceropegia. 



angle often produced into a tooth or spur. Column sliort, anthers 

 conniving over the stigma with tips membranous, rarely 0. Pollinia 

 1 in each cell, erect waxy pedicelled. Follicles usually slender with 

 thin pericarp, but variable. Seeds very small ovate or linear-oblong, 

 coma long. 



1. H. pendula, WirjM. 



A fleshy ej^iphyte with rather slender stem, twiggy pendulous 

 branches, oblong, elliptic-ovate or -lanceolate acute thick leaves and 

 white Avaxy flowers '7" diam. with a truncate stellate corona, in short- 

 peduncled pendulous umbels. 



Bihar (possibly Parasnath), Kurzl Parasnath, Anders. A Hoya occurring in 

 Singbhum of which I have not collected the flowers may also l)e this. 



"Branchlets and umbels sparsely hairy, leaves l'5-3", margins recurved, base 

 narrow or rounded, petiole ■2.5-'5". Peduncles -S-'To", pedicels 1-1*5". Sepals- 

 lanceolate, shorter than the corolla-tube, corolla-lobes silkily villous," F.B.I. 



21. LEPTADENIA, Br. 



Twiners or erect and almost leafless shrubs, juice not milky in our 

 species (exc. in fruit). Flowers small in axillary umbelliform cymes. 

 Calyx 5-lobed. Corolla sub-rotate with spreading pubescent or bearded 

 lobes, valvate in bud. Corona double ; corolline of small j^rocesses in 

 the throat between the lobes, staminal of an annular thickening or 

 undulate wing. Column short ; anthers inflexed at tip and ligulate 

 or appendiculate, not membranous ; pollinia 1 in each cell, globose, 

 erect, subsessile, tips with a small hyaline appendage. Stigma flat, 

 5-gonal. Follicles hard, smooth, acuminate. Seeds flat, F.B.I., 

 winged (margins sometimes involute in fresh specimens). 



1. L. reticulata, W. Sf A. 



A twiner with corky bark, tough green branches and thick but not 

 milky juice, young parts hoary tomentose. L. 2-3", ovate, oblong, or 

 some lanceolate, with very obtuse or rounded or subcordate base, 

 mature pale and shortly hairy beneath or pubescent with rather 

 curly hairs or glabrous, often hirtellous above. Petioles slender 

 divaricate -6-1" long. Fls. greenish-white or yellow •2--3" diam. in 

 hoary peduncled axillary sometimes 2-3-nate symes. Follicles green 

 glabrous 3-3'5" with a long acumen and often curved tip. 



Very common near the Puri coast ! Angul ! Fl. .July-Oct. Fr. March. 



Branchlets often glaucous. L. acute or cuspidate, more rarely obtuse and then 

 mostly apiculate, sec. n. about 5-6, rather irregular, reticulations translucent when 

 fresh. Cymes -b-T' diam., rounded, dense ; peduncles •25-*5", pedicels short up to- 

 •25". Calyx pubescent, lobes ovate-oblong. Cor. villous-pubescent with thick 

 lanceolate-acuminate petals with recurved margins and grooved within at base. 

 Staminal corona not very conspicuous. Follicles on short thick stalks, somewhat 

 of the shape of a long-necked bottle, slightly compressed 'S-l" broad (usually much 

 narrower in herbaria), minutely white-dotted, juice yellowish-milky scant, endo- 

 carp rather crustaceous. Seeds "2" linear-obovoid with involute margins. 



22. CEROPEGIA, L. 



Twining rarely erect herbs with a tuberous rootstock. Leaves 

 sometimes minute or 0. Flowers often large, white or greenish and
