Discussion

Subspecies tenuis grows in the foothills of the Sierra Nevada with a disjunct population in the Klamath Range. Some plants from the central Klamath Range are similar to subsp. viscidus, which has three-lobed inflorescence bracts.

Subspecies barbatus is known from Fresno County. The long, dense hairs on the inflorescence bracts help to identify it.
