Discussion

Subspecies leptosepala is known from the Klamath Mountains of California and Oregon and rare northward. It also occurs, intergrading with subsp. laciniata, in the California North Coast Range and east of the Cascade Range in central Oregon and northeastern California. It intergrades with subsp. siskiyouensis in the valleys of the Illinois and Smith rivers, southwestern Oregon and adjacent California (K. L. Chambers 2004b).
