Heuchera elegans
Heuchera rubescens
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.

Heuchera rubescens occurs throughout most of the Intermountain Region except the Uinta Mountains and basin in Utah.
This complex has always been extremely difficult taxonomically. Almost every minor variant in such characters as the level of insertion of stamens in relation to petals, the shape and length of hypanthium and petals, the size, hairiness, and shape of leaf blades, and the length of petioles has been given a name and recognized at various taxonomic ranks, often without correlation to any pattern of geographical distribution. We agree with P. K. Holmgren and N. H. Holmgren (1997) that, pending a thorough phylogenetic study, it seems best to recognize a single polymorphic species without infraspecific taxa.
The Gosiute Indians used a decoction of roots of Heuchera rubescens as an astringent on the skin and gave it to babies with colic. The Paiute used an infusion of roots as an eyewash and took a decoction of roots for venereal disease. The Shoshoni took an infusion of the roots for diarrhea and liver trouble or biliousness; they used a decoction of the roots for high fever, heart trouble, venereal disease, and general debility. They also used mashed, boiled leaves as a wash for horses’ saddle sores and gave soaked roots to horses and cows for cramps (D. E. Moerman 1998).
