Heuchera elegans
Heuchera caespitosa
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.

Of conservation concern.
Heuchera caespitosa occurs in the western Transverse Ranges in Kern, San Bernardino, Tulare, and Ventura counties, and in the Outer South Coast Ranges, southern Sierra Nevada foothills, and southern Sierra Nevada. It is very similar to H. abramsii, H. brevistaminea, H. hirsutissima, and H. pulchella; the group needs thorough phylogenetic analysis.
