Description

This species is extensively branched above ground with small leaves and flowers. Variety pilosa differs by its uneven calyx pubescence and acute calyx lobes.

Distribution

Mexico, southwest NM, southern AZ to central coastal CA.

Habitat

Upper Sonoran and lower transition zones on wet or humus soils in canyons (Shreve and Wiggins 1964).

Remarks

Oxalis corniculata is variable and widespread in North America. Turner (1994) draws a line between var. pilosa and var. wrightii in TX and NM that approximates the Mexican border. He says there is a broad band of hybridization between these varieties. The Wager and Sabo collection has both acute and obtuse calyx lobes on the same flowers and may be such a hybrid.
