    Habit
    Perennial herbs or branched shrublets mostly with erect stems
    Leaves
    Leaves sessile, linear to lanceolate, the lateral nerves rather obscure; stipules with the truncate sheath bearing hairs and colleters or 2–several teeth
    Flowers
    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
    Calyx-lobes 4, linear-subulate
    Corolla
    Corolla salver-shaped with a long narrowly cylindrical tube; lobes 4; throat and lobes within glabrous or sparsely pilose
    Stamens
    Stamens always included in the tube or only the tips of the anthers exserted
    Pistil
    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
