Discussion

Of conservation concern.

Heuchera hirsutissima is known from Mount San Jacinto and the San Jacinto Mountains of Riverside County and possibly the San Bernardino Mountains of San Bernardino County. It resembles H. caespitosa and H. elegans, except for its densely villous hypanthium and minute adaxial sepals.

Heuchera elegans occurs in the mountains of southern California, chiefly in the San Gabriel Range in Los Angeles and San Bernardino counties and vicinity. It resembles H. caespitosa. This group is in need of phylogenetic study.
