'''''Calandrinia''''' is a genus of flowering plants known as '''purslanes''' and '''redmaids'''. It includes 37 species of annual and perennial herbs which bear colorful flowers in shades of red to purple and white. Species of this genus are native to the Americas, including western and southern South America, Central America, and western North America.<ref name=powo/><ref>[https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:77311196-1 ''Calandrinia petrophila'' J.G.West & Albr.] ''Plants of the World Online''.

==Description== Species in the genus ''Calandrinia'' are annual or perennial herbaceous plants with a sprawling or erect habit. The leaves are mostly basal and may be either alternate or opposite in arrangement. Flowers are produced in cymes. Each flower produces between four and eleven petals, though often five. Flowers may be white, purple, pink, red, or yellow.<ref name=vf/><ref name=fna/><ref name=elve2015/>

==Taxonomy== The genus ''Calandrinia'' was erected in 1823 by German botanist Carl Sigismund Kunth.<ref name=kunth1823/><ref name=ipni/> It was named for Jean Louis Calandrini (1703–1758), a Genevan botanist.<ref name=fna/>
