Taxonomic Comments

Kartesz (1999) includes all material of Claytonia spathulata (Kartesz 1994) in C. exigua ssp. exigua. Per Miller and Chambers (1993), Claytonia spathulata is an invalid name: "The name Claytonia exigua Torrey & A. Gray, of 1838, must replace the earlier C. spathulata Douglas ex Hooker, 1832, because the latter is a homonym of C. spathulata Eaton, 1824."
