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 eastwoodiae occurs in central Arizona and is unique in the genus for its hexamerous flowers. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
