Discussion | Heuchera abramsii occurs in the San Antonio Mountains and the eastern part of the San Gabriel Mountains, San Bernardino and Los Angeles counties. It closely resembles H. brevistaminea, H. caespitosa, H. elegans, and H. pulchella. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 5 (5 in the flora). The Skagit Indians rubbed pounded plants of Heuchera micrantha on hair to make it grow and applied it to cuts. The Thompson Indians used a mashed poultice of this root mixed with Douglas fir pitch for wounds. Chewed leaves and roots were spat on sores or wounds. Infusions of roots were taken for liver trouble and sore throat. Small, peeled, cleaned root pieces were chewed for mouth sores and gum boils (D. E. Moerman 1998).
