Tropical wood-sorrel Tropical wood-sorrel

Varieties 5–7 (1 in the flora): introduced, California; Africa (South Africa); introduced also in Europe, Australia.

Oxalis hirta is recognized by its rhizomatous habit, sessile to subsessile leaves with unlobed leaflets, and large, solitary, axillary flowers. Plants apparently do not fruit in California. T. M. Salter (1944) referred to O. hirta as a polymorphous group-species and recognized seven varieties in South Africa, primarily based on variation in habit and corolla color (white to pink, purplish, or yellowish) and shape (funnelform to cylindric).
