Heuchera abramsii
Heuchera glabra
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.

Heuchera glabra occurs from near sea level in the Aleutian Islands and the Panhandle in Alaska to above the tree line on Mount Hood, Oregon, in the Cascades, Olympic Mountains, and Wenatchee Mountains in Washington, and in the Coast Mountains to the Selkirks Range in British Columbia. It intergrades with H. micrantha where their ranges overlap in British Columbia, and where the two species probably hybridize. It tends to occur at higher elevations than does H. micrantha. The Tlingit used this species to treat inflammation of the testicles from syphilis (D. E. Moerman 1998).
