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 hallii occurs in south-central Colorado. It resembles H. bracteata in shape and size of the flowers and congestion of the inflorescence. It is distinguished by having stamens and styles included; H. bracteata has stamens and styles exserted.
