Hypoxidaceae

Flowers of Spiloxene capensis, from the Barrett Lab.


Belongs within: Liliidae.

The Hypoxidaceae are a family of rhizomatous or cormous plants found mostly in the Southern Hemisphere and tropical Asia.

Characters (from Healy & Edgar 1980): Herbs with tuberous rhizome or corm covered with membranous or fibrous sheaths. Leaves usually all basal, often with long hairs. Flowers bisexual, actinomorphic, mostly white or yellow, solitary, or in spicate, racemose or subumbellate inflorescences; segments 6, subequal, free or basally connate. Stamens usually 6, inserted at base of perianth-segments; anthers often 2-lobed at base, opening by longitudinal slits. Ovary inferior, trilocular; ovules usually many, in two series on axile placenta in each locule. Fruit usually a capsule crowned by persistent perianth; dehiscence by irregular, often more or less circular slits; fruit occasionally fleshy and indehiscent. Seeds small, often black.
