alternate with the branches, in young luxuriant plants cor- 
date, in others oblong, or broad-lanceolate, pointed, three-

duncles solitary, leaf-opposed or in the divisions of the 
branches, round, scabrous, one-flowered, Flowers small,

Annual, cespitose. Leaves alternate, and divided into nu- 
merous capillary segments, 
A native of Coromandel, where it appears on low sandy 
moist ground during the dry season, 
Willdenow dlega f Bes Zinnia bidens (Retz. Obs, vi, 28,) to 
be this plant. It is very different, and according to my idea, 
a very perfect Zinnia, with a herbaceous, rigidly erect stem, 
and pinnatifid leaves; whereas this lies flat on the ground, 
and leaves bi- and tripinnate.
