Calandrinia is a genus of known as purslanes and redmaids. It includes 37 species of annual and perennial 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.[ Calandrinia petrophila J.G.West & Albr. Plants of the World Online. Retrieved 21 February 2024.] Some species have been introduced to parts of Australia, New Zealand, southern Africa, Asia, and Europe.[ Over 60 species native to Australia and New Guinea that were formerly included in Calandrinia are now placed in a separate genus, Rumicastrum or Parakeelya.][Judy G.

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.[

Taxonomy
The genus Calandrinia was erected in 1823 by German botanist Carl Sigismund Kunth.[ It was named for Jean Louis Calandrini (1703–1758), a Genevan botanist.][
]
Approximately 74 Calandrinia species are native to Australia.
Despite this, the nomenclature has not been officially changed for all Australian Calandrinia, including C. balonensis. Although the need for a nomenclature change is widely agreed, a debate has arisen over the appropriate naming of the Australian Calandrinia.[ Rumicastrum Ulbr. Plants of the World Online. Accessed 17 November 2023.] The proposal to rename Calandrinia as Parakeelya has not yet been decided.
The genus is classified in the family Montiaceae.[ It was previously placed in the purslane family, Portulacaceae.][
