Leptosyne
(from leptosein, slenderness; a name applicable to the original, but not to most of the species, except as to the leaves and their divisions). ORD. Compositae. A genus (now included, by Bentham and Hooker, under Coreopsis, but regarded as distinct by Dr. Asa Gray) containing about seven species of New World annual or perennial, herbaceous or suffruticose, smooth and glabrous plants, with showy pedunculate heads--the ray and disk being both bright yellow--and pinnately divided or dissected leaves. They have the habit of Coreopsis (which they represent on the Western side of North America), "but mostly with pistillate rays, and always with a ring on the tube of the disk corollas, or at its juncture with the throat" (Gray). For culture, see Coreopsis.

Autumn. l. bipinnately divided into narrowly linear lobes of a line or two in width. h. 1ft. Perennial. (B. M. 6241, under name of Coreopsis maritima.) L. maritima, of "Revue Horticole" (maritime).
