Leptosyne (Greek, slenderness). Compositae. Yellow-flowered composites, with much-divided foliage like cosmos. Smooth and glabrous herbs and subshrubs: leaves alternate or opposite, usually rather fleshy, and ter- nately or pinnately divided or dissected. They are the representatives of Coreopsis on the western side of the continent, but have mostly pistillate rays and always a ring on the tube of the disk-flowers. —Seven species, all from Calif, except L. arizonica. The genus is united with Coreopsis by some authors, including Hoffmann in Engler & Prantl. In the North these plants are mostly treated as half-hardy annuals. None of them has anything like the popularity of either cosmos or Coreopsis tinctoria. The commonest species is L. maritima, but L. Stillmanii promises to outrank it, although not well known in the trade. L. Stillmanii is said to bear flowers 1 1/2 inches across, for 5 or 6 weeks. Its seed germinates quickly and can be sown outdoors. Sandy soil and a sunny position are advised. It is said to bloom in four to five weeks after sowing. L. maritima should be started indoors, transplanted in May, and can be brought into flower by July. Two distinct plants are passing in the trade as L. maritima, one of which is L. calliopsidea, and is considered an inferior plant by some. The seeds of the two plants are easily distinguished.
