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.
