A milky shrub. Stems twining: the hark rough and cracked; 

 on the branches about one year old, cinerous and tubercu- 

 lated. Petioles 1-2 inches long, round, smooth, and with the 

 young shoots and peduncles sprinkled all over with an im- 

 palpable whitish powder. Leaves sometimes ovate, sometimes 

 deeply cordate and acuminate, (perhaps these constitute 

 different species,) of a thin membranous texture, and, like the 

 other parts, sometimes powdery. Flowers green, in lateral 

 simple umbels ; peduncles about as long as the petioles : pedi- 

 cels nearly the same length. Calyx 5-parted, small. Corolla 

 rotate, 5-cleft, divisions obtuse. Croivn of the stametis of 5 

 fleshy truncated bodies, attached to the top of the column, 

 each furnished with a little tooth, projecting from the interior 

 angle, which rests on the adjoining anther. Anthers ter- 

 minated by a membrane, resting on the stigma. Pollen-masses 

 erect, compressed. Pistil : Germens 2 : Styles short and 

 very thick : Stigma slightly convex. Pericarp ; 2 follicles 

 adhering at the base, and diverging, ventricose in the middle,
