Discussion | Heuchera glomerulata occurs in the Chiricahua and Pinaleno mountains of southeastern Arizona and in New Mexico. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
