Discussion
Columbiadoria hallii is known from the vicinity of the eastern Columbia River Gorge. It occurs also “at scattered stations [south] in the Cascades to the Calapooia Mountains,” where the plants “are not precisely like the others, and may prove to be varietally distinct” (A. Cronquist 1955, p. 216).
