  • Inflorescence a terminal raceme of many, small flowers, rarely branched; peduncle erect; bracts small, filiform, decurrent, each often with a small lateral bracteole
  • Flowers usually blue, occasionally white tinged pinkish mauve or with a greenish mark at tepal apex; pedicels spreading, short or long, sometimes paired
  • Tepals free, spreading or strongly recurved, narrowly ovate, persistent
  • Stamens 6; filaments fused to base of tepals, fused at base, spreading, flattened; anthers versatile, introrse
  • Ovary globose to oblong; ovules several to many; style filiform; stigma apical
  • Fruit a membranous capsule, dehiscing loculicidally
  • Seeds rounded, obtusely angled, black, verrucose
