Herbs, shrubs, rarely trees. Leaves opposite, alternate, verticillate or in rosettes, exstipulate. Inflorescences usually cymes, rarely racemes, axillary or pseudoterminal. Flowers perfect, zygomorphic, seldom actinomorphic. Calyx (4-)5-divided. Corolla gamopetalous, usually 2-lipped. Stamens 2–5; anthers free or coherent, thecae 2, parallel, divergent or divaricate; staminodes 1–3 or absent. Disc ringlike to cup-shaped, rarely absent. Ovary superior (all native taxa in Taiwan) to inferior, 1-loculed, placentation parietal, rarely 2-loculed and placentation axile; ovules numerous, anatropous; style 1, terminal; stigmas 1 or 2. Fruit usually a capsule, loculicidally, septicidally, or circumscissilely dehiscent, rarely a berry.

Subshrubs or climbing lianas, epiphytic, rarely epipetric or terrestrial. Stems branched or simple. Leaves usually many, opposite or whorled, rarely alternate, equal to subequal in pairs. Cymes axillary; bracts 2, opposite. Calyx actinomorphic, 5-merous, divided to base or 5-lobed. Corolla purple to reddish, white or yellow, zygomorphic, glabrous or puberulous inside, tube funnelform to tubular, longer than limb; limb 2-lipped, upper lip 2-lobed, shorter than lower lip, abaxial lip 3-lobed, lobes equal or central lobe longer, apex rounded. Stamens 2, adnate to middle, seldom to near base of abaxial side of corolla tube, included; anthers basifixed, coherent, thecae nearly parallel, not confluent, dehiscing longitudinally; connective sometimes appendiculate; staminodes 2 or 3, adnate to adaxial side of corolla tube. Disc ring-like to cup-shaped. Ovary linear, 1-loculed, placentas 2, parietal, projecting inward, bifid; stigma terminal, depressed-globose. Capsule linear, dehiscing loculicidally to base, valves 4 or 2, straight. Seeds with 1 hair-like or subulate appendage at each end.
