Discussion

Variety obtusifolium is known from coastal southern California (southern Orange and San Diego counties) and northern Baja California, where it introgresses with </i>var.<i> fasciculatum, resulting in shorter, more strongly hairy stems, and leaves less apiculate or mixed obtuse-acute in some interior populations.
