Species In Genus: 500--950 species: especially temperate. Etymology: (Greek: sour, from acidic taste) Note: Taxonomy difficult, needs study; generally heterostylous; many (especially aliens in California except Oxalis micrantha) ornamental; some noxious weeds; oxalates may be TOXIC to livestock; Oxalis latifolia Kunth possibly naturalized in CCo (Keil 30389, just north of San Simeon), differs from Oxalis purpurea in having flowers in umbel-like cyme; Oxalis hirta L. an historical waif (no recent collections), excluded.
