Discussion

Balsamorhiza deltoidea varies in the crenation of the leaf margins. The variability may stem from an old hybridization with B. hookeri or other species of Balsamorhiza. Otherwise, B. deltoidea shows little significant variability except where it hybridizes with B. careyana in the narrows of the Columbia River Gorge.
