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 wootonii occurs in the Sacramento and White mountains of south-central New Mexico. It resembles H. parvifolia. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
