Trianthema is a genus of flowering plants in the ice plant family, Aizoaceae. Members of the genus are annuals or perennials generally characterized by fleshy, opposite, unequal, smooth-margined leaves, a prostrate growth form, flowers with five perianth segments subtended by a pair of bracts, and a fruit with a winged lid. The genus contains about 30 described species growing in tropical and subtropical regions, especially Australia. One common species, Trianthema portulacastrum, desert horse purslane, is frequent as a weed in agricultural areas and is widely distributed.[2]
Taxonomy
The genus Trianthema was first formally described in 1753 by Carl Linnaeus in Species Plantarum.[1][3]
