Dodecatheon austrofrigidum
Dodecatheon redolens
Of conservation concern.
Dodecatheon austrofrigidum occurs mainly in the mountains near the coast of Washington from the southern Olympic Peninsula (Grays Harbor and Pacific counties) to northwestern Oregon (Clatsop and Tillamook counties). The populations are widely scattered and always with relatively few individuals. At higher elevations (e.g., ca. 1200 m atop Saddle Mountain, Tillamook County), D. austrofrigidum occurs in moist, grassy turf. At lower elevations in the same area, it occurs on stream banks in the narrow zone between the high- and low-water mark, persisting in cracks of basaltic rocks. The degree of denticulation of the leaves appears to vary among populations; some larger plants have toothed leaf blades even prior to anthesis.

Dodecatheon redolens occurs mainly in the high mountains of the southern Sierra Nevada, with scattered populations in the San Bernardino, San Gabriel, and San Jacinto mountains of southern California. Elsewhere in California, it occurs on scattered desert ranges in the northern Mojave Desert. In the Intermountain West, it is found occasionally in Inyo and Mono counties on the eastern foothills of the Sierra Nevada, the White Mountains, and on or near Glass Mountain. It is found across central Nevada to the Independence and Ruby mountains of Elko County, and the Deep Creek Range of west-central Utah.
Although difficult to see, a fairly good feature of Dodecatheon redolens is that the corolla tube usually covers the filaments and proximal end of the anthers. In both D. jeffreyi and D. alpinum, the corolla tube does not cover the base of the anthers. In addition, the tips of the anthers in the latter two species are truncate to obtuse; in D. redolens they are acute.
