  • Erect, tough, tufted perennials; rhizome relatively short, vertical, whitish in transection, lower part of rhizome dark, verrucose, with one thick root emerging from each wart-like lobe; upper part bearing several leaves and, below them, dense, fibrous, brownish black sheaths of old leaves
  • Leaves basal, distichous, about 6 per shoot, linear, rigid, ribbed, glabrous, sheathing at base

  • Perianth with short tube and 6 spreading, linear segments, villous outside, glabrous and a mauvy-pink inside
  • Stamens 3 + 3, erect, short outer filaments arising from throat of perianth, 3 inner somewhat shorter; anthers versatile, sagittate, opening by longitudinal slits
  • Ovary subinferior, protruding somewhat above, 3-locular; ovules axile, anatropous, 2 in each locule; style subulate, exserted; stigma small, 3-lobed
  • Capsule subglobose, 1-seeded, crowned with persistent perianth; fertile locule dehiscing loculicidally
