Stylosanthes
(from stylos, a style, and anthos, a flower; alluding to the very long style). Pencil Flower. ORD. Leguminosae. A genus comprising about fifteen species of stove or greenhouse, perennial herbs, natives of Asia, Africa, North America, and Brazil. Flowers yellow (or white ?), variously disposed; calyx tube filiform, with membranous lobes; petals and stamens inserted at the apex of the tube; standard orbicular. Leaves pinnately trifoliolate, exstipellate; stipules adnate to the bases of the petioles. Several of the species have been introduced, but they are scarcely worthy of cultivation, except in botanical collections.
