Balsamorhiza hispidula
Balsamorhiza macrolepis
Distribution of Balsamorhiza hispidula is highly disrupted in the southern part of its range.

Of conservation concern.
Balsamorhiza macrolepis grows in the western foothills of central Sierra Nevada and in the eastern San Francisco Bay area (there mostly extirpated). The tall habit, exhibiting gigas characteristics, suggests that, like B. macrophylla, this taxon may be a polyploid. No hybrids with other species have been noted.
