Thevetia (named for Andre Thevet, a French monk, 1502-1590). Apocynaceae. Glabrous small trees or shrubs which are grown in the warmhouse, or outdoors in warm climates.
Leaves alternate, 1-nerved or lightly feather-veined: fls. large, yellow, in terminal, few-fld. cymes; calyx 5-parted, many-glanded inside at the base, segms. acute, spreading; corolla funnelform: lobes broad, twisted; disk none; ovary shortly or deeply 2-lobed, 2-celled: drupe broader than long, 2-celled.—About 10 species, Trop. Mex. southward to Paraguay.
The yellow oleander of Florida gardens, T. nereifolia, is a very ornamental small evergreen shrub, growing luxuriantly in rich sandy soil, not too moist and not too dry, ultimately attaining a height of 6 to 8 feet and almost as much in diameter. The foliage is abundant, light glossy green, and reminds one of the oleander, but the leaves are narrower. The pale yellow flowers are abundantly produced. The fruit, which is of the size and somewhat of the form of a hickory-nut, is regarded as poisonous by the negroes. Thevetia can stand a few degrees of frost. If banked with dry sand in fall it does not suffer to any great extent, although the top may be killed. CH
