Herbage usually copiously arachnose, tomentose, or villous at flowering. Leaves: basal and proximal cauline distinctly petiolate; blades (cauline) usually lanceolate to oblanceolate. Heads 6–12 (–30+). Phyllaries linear-subulate, 8–12 mm, tips usually green, minutely, if at all, black. Ray-florets usually 5; corollas yellow, laminae mostly 5–8 mm.


Phenology: Flowering spring.
Habitat: Openings in coniferous woodlands and woodland-sagebrush associations
Elevation: 100–3600 m
