Discussion

Subshrubby or shrubby forms of var. pinnata were recognized as a distinct var. or subsp. inyoensis. Although such growth forms occur primarily in southern California, western Nevada, and southwestern Utah, they occur sporadically throughout the species range, especially in desert habitats with sand dunes.
