Description:

  • Perennial, deciduous, glabrous, bulbous herbs
  • Bulb subglobose to globose-depressed, up to 150 mm in diameter, usually exposed above ground; with or without grey, withered, membranous outer scales, inner scales thick, white or green if exposed to light
  • Leaves 1-few, soon withering and falling, linear, small, canaliculate
  • Inflorescence: axis (stem) much branched, succulent, scrambling or pendulous, up to 2-3 m long, annual, glabrous, bright green or glaucous, branches reflexed-spreading; bracts narrowly triangular or lanceolate, spurred
  • Flowers green, yellowish green or white, diurnal; pedicels long, arched
  • Tepals free or fused only at base; lobes spreading or reflexed, oblong to lanceolate with incurved tips, persistent in fruit
  • Stamens 6, arising from base of tepals; filaments free; anthers oblong, introrse
  • Ovary subglobose to conical; ovules many; style terete, with a clavate, 3-lobed stigma
  • Fruit a globose or ovoid capsule, trigonous; valves emarginate or tapering into style, with or without a little horn above middle of each valve; dehiscing loculicidally
  • Seeds few, flattened, shiny black
