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.

Heuchera chlorantha occurs in the Pacific Northwest north to the Queen Charlotte Islands of British Columbia. Inland, it occurs from the eastern base of the Cascade Mountains westward in Oregon and Washington. A putative hybrid between H. chlorantha and H. micrantha var. diversifolia, named H. ×easthamii Calder & Savile, has been reported in the Hazelton region of British Columbia. The leaf form and capsule size are intermediate between those of the two parents, both of which occur in the region.
