Discussion | 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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Heuchera pilosissima occurs in the marine zone and in the Coast Ranges. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
