 with the posterior lobes rounded, but somewhat angular. 

 Peduncles rigid, umbelliferous. Calyx smooth. Lobes of

A native of the Moluccas; and from thence introduced in- 

 to the Botanic garden at Calcutta in 1800 ; where it bios-

Root perennial. Stems and branches creeping, pentan- 

 gular ; young parts villous, and sometimes twining, though 

 not readily ; length of the whole plant from two to three fa- 

 thoms. Leaves petioled, the lower ones broad-cordate-sagit- 

 tate ; the superior ones narrow-sagittate ; in all the posterior 

 lobes are large, and rounded, though frequently a little an- 

 gular ; margins generally entire; both sides very villous; 

 length from one to four inches. Petioles scarcely half the 

 length of the leaves, channelled, villous, at the base swelled 

 on each side into two glandular, stipulary knobs. Peduncles 

 axillary, solitary, erect, rigid, clavate, villous, about as long 

 as the petioles, supporting a trichotomous, corymbiform um- 

 bel, of many, pretty large, pure white, inodorous flowers. Pe- 

 dicels shorter than the peduncles, but like them clavate, and 

 villous. Bractes many, caducous, and of various sizes. 

 Calg x ; leaflets oval, concave, slightly villous, much shorter 

 than the tube of the corol. Corol perfectly campanulate. 

 Border divided into five semi-circular lobes. Stamina hid 

 in the tube. Style about as long as the stamens, of two 

 round lobes. Seed dark-brownish black, and covered with 

 much soft hair, of the same colour.
