}}Claytonia (spring beauty) is a genus of flowering plants native to North America, Central America, and Asia.[ The genus was formerly included in Portulacaceae][ but is now classified in the family Montiaceae,][ primarily native to the mountain chains of Asia and North America, with a couple of species extending south to Guatemala in Central America, and northwest to Kazakhstan, Mongolia, and Russia in eastern Asia.] The genus Claytonia was moved in 2009 from the purslane family (Portulacaceae) with adoption of the APG IV system, which recognised the Montiaceae family. A number of the species were formerly treated in the related genus Montia. A comprehensive scientific study of Claytonia was published in 2006.[1] Claytonia perfoliata, the species for which the term miner's lettuce was coined, is distributed throughout the Mountain West of North America in moist soils and prefers areas which have been recently disturbed. The species got its name due to its use as a fresh salad green by miners in the 1849 Gold Rush in California.{{cn|date=January 2019}} Species{{As of|January 2019}}, Kew's Plants of the World Online lists 33 accepted species:[{{Columns-list|colwidth=35em|]- Claytonia acutifolia Pall. ex Willd.
