Dodecatheon austrofrigidum
Dodecatheon utahense
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.

Of conservation concern.
Dodecatheon utahense is known only from from both sides of the road at Moss Ledge in Big Cottonwood Canyon and from the Lake Blance area, Salt Lake County. The plants can have a narrow caudex to which long trailing leaves and roots are attached, the plants often hanging from steep canyon walls. Other plants tend to occur in the cracks of the rocks on a compact caudex; these plants usually are upright and tend to be much shorter (to 20 cm) compared to the hanging plants.
