Bioscorea. dioecia hexandria. 80.'J 



10. D. angnina. R. 



Tvhors oylindric. ^Vews twinino", round, villous. Leaves 

 opposite and alternate, cordale, five-neivcd. Male spikes 

 crowded, pendulous. 



Beng. Kookoor aloo. 



Tiiis species I have found in its wild state in woods about 

 Calcutta. Flowering- time the close of the rains. 



Tubers columnar, in a looser soil perpendicular, in a hard 

 one variously bent. Stems and brcmches twining- up and over 

 trees and bushes, perfectly round, and covered with short soft 

 down. Leaves opposite and alternate, petioled, exactly cor- 

 date, entire, Hve-nerved, with many transverse veins between 

 them, from four to six inches long-, and from three to five 

 broad, female spi/ces axillary, erect, long, simple or com- 

 pound, villous, with remote, small, green, villous flowers. 

 Calyx as in the genus. 



The root is not much esteemed, though eaten by the poor 

 M'hen hard pressed for food. In shape it agrees with that of 

 lliimpldns's Ubium angu'mum, vol. v. t. 122. but the leaves 

 differ much. 



11. D. nummularia. Willd. iv. 792* 



Tubers ligneous, irregular. Stems twining, perennial, 

 prickly towards the base. Leaves opposite, cordate, five- 

 nerved, very smooth on both sides. 



Hind, and Beny. Shora-aloo. 



This species 1 took for D. oppositifolia for seme time, but 

 on finding- some old plants with the stems ligneous, and arm- 

 ed with numerous, sharp prickles, I was convinced it must 

 be a very diflierent species. It is a native of the forests about 

 Calcutta. Flowering- lime the close of the rains. 



Root tuberous, but snjall, and hidden by numerous strong 

 fibres. Stem many fathoms long, twining, with the lower part 

 ligneous and prickly, the rest round, and very smooth. Leaves 

 toward the base of the stem alternate, all the rest opposite, 

 petioled, cordale, five-nervetl, very smooth on both sides,
