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.

型態特徵
Rosulate or caulescent perennial herbs, often woody at base. Leaves opposite, or spiral in some rosulate species, petiolate, simple, upper surface usually thinly arachnoid, often glabrescent or scabrous, hairs on lower surface usually densely interwoven and usually branched, at least once near base, more rarely indumentum of spaced or clustered branched, stellate or dendroid hairs. Cymes axillary, or forming a thyrsoid terminal panicle; bracts 1–2. Calyx divided almost to base into 5 segments. Corolla white, blue or violet, obliquely campanulate or with short tube and flat limb, slightly bilabiate, upper lip 2-lobed, lower lip 3-lobed. Disc wanting. Stamens included, seldom exserted, fertile 2 usually adnate near corolla base; filaments usually thick; anthers robust, coherent apically, thecae divaricate, confluent. Ovary more or less cylindrical, tapering smoothly into the style; stigma small, capitate, rarely sublinguiform. Capsule linear, loculicidally dehiscent and usually spirally twisted. Seeds narrowly elliptic to fusiform, without appendages.
