Balsamorhiza careyana
Balsamorhiza lanata
Hybrids involving Balsamorhiza careyana and B. deltoidea occur near the Columbia River Gorge; intermediates are found to the east and south. In northern Oregon, plants in some populations have glabrous cypselae and some populations are mixed. The hairiness may come from B. rosea; B. rosea and B. careyana may hybridize profusely, producing mostly plants with the stature of B. careyana and with the relatively short, brick-red ray corollas of B. rosea. Hybridization also occurs, occasionally, between B. careyana and B. sagittata; B. careyana also hybridizes with any species of sect. Balsamorhiza with which it comes in contact. Plants called Balsamorhiza careyana var. intermedia usually have crenate leaf margins and glabrous cypselae.

Of conservation concern.
Balsamorhiza lanata is known from a relatively restricted area in northern California and southern Oregon. No hybrids between it and other species have been noted.
