A native of the tropical zone all round the world. 
An annual nettle-like plant with slightly stinging hairs, co- 
piously branched, and attaining a height of three or four feet 
when well-developed. Stems quite herbaceous and easily com- 
pressible, the main ones a quarter of an inch in thickness, usually 
not pubescent, but copiously clothed with spreading filiform 
bristly gland-tipped hairs, the longest an eighth of an inch long. 
Stipules membranous, bifid to the middle, the divisions filiform. 
Petioles weak, herbaceous, one to four inches long. Leaves 
ovate, five or six inches long when full-grown by three or four 
inches broad, the point acute, the edge all round with deltoid 
serrations to a depth of above a line, the base broadly rounded or 
slightly cordate, the veins prominent, texture quite membranaceo- 
papyraceous, the upper surface dark green, the lower much paler, 
both more or less furnished with bristly hairs like those of the 
stem. Flowers in thyrsoid subdeltoid panicles three to five inches 
long, on herbaceous erect peduncles one or two inches long from 
the axils of the leaves; all the branches of the panicle deltoid, 
with a naked space between them, the ultimate clusters crowded ; 
pedicels exceeding the flowers ; the male and female flowers dif- 
ferent, but occurring in the same clusters. Female calyx with 
the two lateral divisions much larger than the other two; the 
fruit when developed deflexed, ovate in general outline but
