Hypoxidaceae is a family of flowering plants, placed in the order Asparagales of the monocots.

[1] The APG IV system of 2016 (unchanged from the 1998, 2003, and 2009 versions) recognizes this family.

[4] The members of the family are small to medium herbs, with grass-like leaves and an invisible stem, modified into a corm or a rhizome.

The flowers are born on leafless shoots, also called scapes.

Curculin is a taste modifying sweet protein that was discovered from the fruit of a plant in this family (Curculigo latifolia).
