Root fibrous. Stems filiform, round, smooth, green, voluble. Leaves 

 shortly petioled, opposite, linear-lanceolate, acute, rounded and sub- 

 cordate at the base, entire, smooth, deep green above, paler and veined 

 beneath, deciduous ? From 2 to 3 inches long, by about an inch 

 broad. Racemes axillary, long-peduncled, bearing from 3 to 8 large, 

 sub-campanulate, 5-cleft flowers ; their segments triangular, acute, ex- 

 ternally of a pale rosy hue, internally purplish, marked with darker 

 lines. Column of fructification prominent ; crown of 5 inflated leaves, 

 broad, and somewhat compressed at the base, tapering to a sharp 

 incurved point. Anthers terminated by a membrane. Pollen-masses 

 compressed, attached by their attenuated apex, pendulous. Stigma 

 large, flat, covered on the edges by the membranous lips of the anthers. 

 Pericarps two large inflated follicles : these consist of two coats or 

 layers, loosely attached to each other, and it is between these that the 

 inflation takes place, as the inner coat is of a firm texture, and closely 

 embraces the seeds, which are numerous and comose. Wight. Said 

 by De Candolle to be eatable ; but Roxburgh says he did not find that 

 the natives ever eat it, and Dr. Wight makes the same statement j 

 adding, however, that in decoction it is used as a gargle for aphthous 

 affections of the mouth and fauces.
