Conostomium (Stapf) Cufod.

Perennial herbs or branched shrublets mostly with erect stems. Leaves sessile, linear to lanceolate, the lateral nerves rather obscure; stipules with the truncate sheath bearing hairs and colleters or 2–several teeth. Flowers small to fairly large, never truly heterostylous, either in terminal corymbs, spike-like inflorescences or solitary or in pairs or fascicles in the axils of the leaves. Calyx-lobes 4, linear-subulate. Corolla salver-shaped with a long narrowly cylindrical tube; lobes 4; throat and lobes within glabrous or sparsely pilose. Stamens always included in the tube or only the tips of the anthers exserted. Ovary 2-locular; ovules numerous, immersed in the peltate placentas; style usually exserted or rarely included, in which case the stigmas do not reach the bottoms of the anthers; stigma-lobes oblong or linear-oblong, densely papillate. Capsule ovoid or subglobose, crowned by the persistent calyx-lobes and with a usually well developed beak, loculicidally dehiscent at the apex. Seeds numerous, angular, smooth.
