Herbs, erect or ascending, rarely rooting at nodes. Stems 5–90 cm; internodes glaucous, glabrous. Leaves spirally arranged, sessile; blade linear-lanceolate, 5–50 × 0.2–3 cm (distal leaf blades equal to or narrower than sheaths when sheaths opened, flattened), apex acuminate, glaucous, glabrous. Inflorescences terminal, often axillary; bracts foliaceous. Flowers distinctly pedicillate; pedicels 0.8–3 cm, glandular-puberulent, rarely glabrous or glabrescent; sepals 4–11 mm, glandular-puberulent, usually with apical tuft of eglandular hairs, occasionally with scattered eglandular hairs among glandular, rarely glabrous or glabrescent; petals distinct, bright blue to rose or magenta, broadly ovate, not clawed, 6–16 mm; stamens free; filaments bearded. Capsules 4–7 mm. Seeds 2–4 mm.
