See text Calostemma is a small genus of herbaceous, perennial and bulbous plants in the Amaryllis family (Amaryllidaceae, subfamily Amaryllidoideae[2]), commonly known as Wilcannia Lily.

It consists of three species endemic to Australia, where they are distributed in arid regions with summer precipitation.

Members of Calostemma often flower in a leafless state, the narrow, shining-green, strap-like leaves usually preceding flowering and reaching a length of 25–30 cm.

The list of Calostemma species, with their complete scientific name and authority, is given below.

[3] Due to their large and showy flowers, members of this genus are used as ornamental plants.
