 1. UMoralis, from his short character and from Miqnel's description, is evidently a very 

 different plant, probably closely allied to, if not identical with, /. reniformis. Some ot 

 Dallarhy's specimens of /. denticulata have the leaves more acute and acutely aunculate, 

 almost like those of J. gracilis^ but with the calyx of /. denticulata. 



22. I, gracilis, R, Br. Prod. 484. A ratlier slender twiner, glabrous 

 or scabrous-pubescent. Leaves on long petioles, lanceolate-hastate or tn- 

 angular-cordate, acute, mostly 1 to 2 in. long, the basal lobes or aimcles 

 usually acute long and divergent or curved inwartis towards the end, but 

 varying in breadth and sometimes but rarely almost obtuse. Peduncles, ui- 

 cluding the pedicel, as long as the petioles, bearing a single rather large 

 white flower, the bracts very small. Sepals broadly lanceolate, acute or acu- 

 minate or rarely obtuse, 4 to 5 lines long or G lines when in fruit. Corolla 

 about 2 in. long. Cnpsule globular, smooth, 5 to 6 lines diameter. _ Seeds 

 shortly pubescent, with a tuft of longer hairs at the hilum.— Chois. m i^^-
