11. HoLOSTEMMA.] 90. ASCLEFIDACE^. 



Note.— Following the F.B.I. I have described the corona as single in the Key^ 

 but it appears to me to be more correctly described as double as above. The 

 annular corona is quite free from the column above. 



1. H. Rheedei, Wall. Syn. H. Elieedianum {Coo'ke in Flora of Bombay, 

 but in the opinion of Hook. f. in F.B.I, this must be a different 

 plant) ; Moron arak', -S. 



A handsome climber with glabro^^s shining stems. Leaves oblong- 

 ovate 3-7" long with deep basal sinus, or upper somewhat triangular, 

 tip cuspidate, glabrovis above, puberulous or thinly pubescent 

 beneath. Flow^ers white or pale-pink outside, crimson inside with 

 corolla •&' long deeply cleft into ovate acute lobes. Follicles 4" by 

 I'S" pustulate. 



Manbhum, Campbell I Dalbhum, Gamble [ Singbhum, in ravines, rare! Fl. 

 July-Sept. Fr. Jan. Also Gorakpur and Sikkim Tarai and therefore probably 

 occurs in Bettiah and Purneah. 



The leaves very closely resemble those of Baphistemma but are not so large nor 

 relatively so broad, tip with a lanceolate cusp •25-*3" long; basal lobes long usually 

 leaving a deep oblong sinus, basal nerves 5-7, sec. n. 2-3 only but intermediate 

 numerous and reticulations stronger than in Baphistemma ; 5-7 subulate glands at 

 base of midrib above. Petiole 1-1'7". 



Leaves eaten, and a decoction of the root given for cough, Campbell. 



12. CYNANCHUM, L. 



Erect or tAvining herbs or shrubs with opp. i-arely whorled leaves 

 and small greenish or purplish flowers in axillary umbelliform race- 

 mose or subpaniculate cymes. Corolla rotate, lobes overlapping to 

 the right or valvate. Corona adnate to the base of the column, 5- 

 partite or cupular or campanulate, varioiisly toothed or lobed, with 

 or without scales or tubercles on the inner face opposite to the lobes. 

 Anthers sessile or stipitate with membranous inflexed tip. Pollinia 

 1 in each cell, j)endulous, waxy, not compressed. Follicle terete or 

 sub-alate. 



1. C. ca lialata, Ham. 



A twiner with variously shaped leaves, the best characters for which 

 are their rather soft fleshy texture, pale glavicous beneath, glabrous, 

 shallow^ cordation and apiculate or shortly cuspidate tip, sec. n. 5-8 

 spreading, looping, obscui'e. Petioles 'o-lT" wdth swollen bases 

 meeting round the stem. Fls. 'S" diam. glabrous in shortly peduncled 

 umbels with, a short ciipular, alternately toothed and crenate, corona. 

 Follicles 2-5-3" lanceolate acuminate with one side flattened subalate 

 on its edges, the other convex wdth two ridges. 



Purneah ! Parasnath, Anders., Clarke ! FI. Sept.-Oct. Fr. Nov. -Jan. 



Young shoots pubescent. L. 2*7-4*5'' long from linear to broadly elliptic or rotund ; 

 my specimens have an emarginate apex with a sharp lanceolate cusp which does 

 not occur in the others. Cymes •7-1" with the peduncle, nearly glabrous. Seeds 

 •3" with the broad wing, broadly obtusely ovate with a long silky coma, base of 

 wing sometimes crenate. 



There are sometimes two small leaflets in the axils of the leaves. 



13. SARGOSTEMMA, Br. 



Shrubs with terete green often jointed branches and very small 

 transient leaves. Flowers rather small, sometimes wax-like, in
