Discussion | Of conservation concern. Heuchera hirsutissima is known from Mount San Jacinto and the San Jacinto Mountains of Riverside County and possibly the San Bernardino Mountains of San Bernardino County. It resembles H. caespitosa and H. elegans, except for its densely villous hypanthium and minute adaxial sepals. (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.) |
