A native of the mountains of Malabar, from thence the seeds 

 were sent by Dr. Buchanan, to the Botanic garden at Calcut- 

 ta, where the plants blossom and ripen their seed during the 

 cold season ; soon after which they perish. 



Root annual, ramous. Stem erect, flexuose, angular, with 

 small white specks, in which are inserted stiff most acute 

 bristles, pointing rigidly in every direction ; branches as cend- 

 ing, and like the stem. Leaves alternate, long-petioled, cor- 

 date, lobate, towards the top of the plant almost palmate, all 

 are grossly serrate, armed with the same bristles as the stem 

 and branches, and some harsh pubescence beside; from 

 four to eight inches long, breadth nearly the same. Petioles 

 about half the length of the leaves, channelled and armed. 

 Stipules large, axillary, solitary, cordate, with the apex end- 

 ino in one or two acute points. Peduncles axillary, the low- 

 er supporting the male, sub-cylindric, amentaceous flowers; 

 those towards the apex of the plant, the female ones, in large, 

 f^lomerate, variously divided spikes. Male flowers as in the 

 "cnus. Female with a cymbiform, tridentate calyx.
