Leaves alternate, crowded or scattered, linear, elongated, elliptical, ovate or obovate, sessile to shortly petiolate, entire, 1-nerved, +/- densely or sparsely papillose, almost glabrous or finely glandular-tomentose. Flowers solitary in leaf axils, very shortly pedicellate with 2 small bracteoles at base, dark blue to violet. Calyx divided almost to base, 5-lobed, +/- valvate; lobes linear, narrow, acute. Corolla tubular, weakly irregular, 5-lobed, much longer than calyx; tube elongated, narrow below then widening suddenly, throat long, mouth wide; lobes +/- equal, free, rounded, spreading, shorter than tube, posterior pair outside in bud. Stamens 4, didynamous, included, arising in lower part of corolla tube; filaments filiform; anthers of equal size, all fertile, transverse, usually ciliate; thecae confluent. Ovary bilocular, +/- narrowly ovate; ovules many; style filiform, exceeding stamens; stigma small, entire, emarginate or slightly bilobed. Fruit a thin-walled capsule, narrowly elongate-ovoid, acute, acuminate or obtusely pointed, somewhat compressed at right angles to septum, bisulcate over septum, longer than calyx, septicidally bivalved, opening +/- to base; valves deeply bilobed. Seeds rugose or scrobiculate-tuberculate.
