Description: Perennial glabrous herbs with corm, dioecious, polygamous or all flowers bisexual; stem or scape unbranched.
Leaves basal or cauline, 1–3, sheathing at base.
Inflorescence a spike or flower solitary; bracts absent. Flowers bisexual or unisexual; male and female flowers in dioecious species dissimilar; male flowers and inflorescences similar to bisexual ones in polygamous species. Tepals usually 6, in 1 whorl, similar, fused towards base, persistent; with 1 or 2 sub-basal nectaries. Stamens 6; anthers dorsifixed or rarely almost basifixed, versatile, dehiscing by longitudinal slits, extrorse. Ovary superior, 3-locular [or 4-locular when tepals 7 or 8]; ovules many per loculus; placentation axile; styles short, free [or fused towards base].
Fruit a capsule, loculicidal or both loculicidal and septicidal; seeds globose, brown.
Distribution and occurrence: World: 40 species, Australia & Africa. Australia: 19 species (endemic), all States.
The nectaries sometimes become paler with age, so that they are similar in colour to the tepals.
