Calyx deeply 5-cleft, the lobes setaceous. Corolla funnelform, thetube slightly curved, enlarged above, or cylindraceous, the limb spreading, 5-lobed, somewhat2-lipped, the lobes rounded, sinistrorsely convolute in the bud. Stamens 4, didynamous,included, all anther-bearing in our species; anther-sacs mucronate at the base. Ovules 2 ineach cell of the ovary; summit of the style recurved; stigma simple, or of 2 unequal oblong, linear, narrowed at the base, 2-4-seeded, in some species coherent. Seeds flat,orbicular, attached by their edges to the retinacula. [Greek, referring to the coherent capsule-valves.] About 30 species, of wide distribution in warm and tropical regions. Besides the following,4 others occur in the southern and southwestern United States. Type species: Dyschoriste depressa I. Dyschoriste oblongifolia (Michx.)Kuntze. Dyschoriste. Fig. 3888.
