Calyx cupulate, about enclosing the corolla tube, lobes ovate-orbicular, deeply divided. Corolla lobes ovate, obtuse, nearly as long as the short-cylindrical tube, erect to spreading. Anthers oval, sessile, or subsessile, at the sinus. Scales triangular, and nearly reaching the stamens, or shorter and truncated, shallowly and irregularly denticulated, bridged at various heights. Ovary globose-conic, styles united, often subulate, of various lengths, but mostly about equal to the young ovary, stigmas small, flat, commonly spreading. Capsule 5-8 mm long, globose-ovate, definitely circumscissile, carrying the withered corolla at the top; seeds about 3 mm long, hilum long, narrow, terminal" (Yuncker, 1932; p. 250).
