Annual, twining, filiform. Leaves cordate, the cauline 

 ones petioled, the floral ones stem-clasping-. Racemes axil- 

 lary and terminal. Corol five-cleft. 



A native of Nepal, from thence introduced by Dr. F. 

 Buchanan, into the Botanic garden, where it blossoms during- 

 the dry season. 



Stems annual, twining - , slender, pretty smooth. Leaves 

 cordate, entire, obtuse-pointed, soft, and smooth, the cauline 

 ones are petioled ; the floral ones sessile, indeed stem-clasp-

 smaller, those of the superior flowers very small. Flowers al- 

 ternate, pedicelled, small, white. Calyx five-leaved; lea'h'l 

 sub-lanceolate, growing' with the pericarp into five scarioe 

 wings. Corol sub-campanulate ; tube short, and rather gib-

 unequal, inserted into the tube of the corol near its bottom. 

 Anthers ovate, within the tube. Germ ovate, one-celled, 

 containing two seeds, attached to its bottom. Style length of 

 the stamens. Stigma oval, apex two-lobed. Utricnlus oval, 

 smooth, of a very delicate, entire, membranaceous texture, 

 surrounded by the five leaflets of the calyx, now enlarged 

 into five scariose, cuneiform wings. Seed as in the preceding-

 cotyledons corrugated. 



N. B. In far the oreater number of our East Indian Con-
