Plants 25–30 cm. Leaves 15–18 × 5–5.5 cm, shallowly lobed, lobes deltate, sharply dentate, faces glabrate. Heads 7–22. Calyculi: bractlets deltate (longest much shorter than phyllaries). Involucres narrowly cylindric or turbinate, 18–21 mm in fruit. Cypselae reddish-brown, 8 mm, apices narrow, not strongly tapered; pappi 12–13 mm. 2n = 55.
Phenology: Flowering May–Jul.
Habitat: Dry open places
Elevation: 400–2200 m
Discussion
Of conservation concern.
Plants of subsp. idahoensis are generally larger and more robust than the other subspecies, with more heads per stem. They are possibly allopolyploids, with Crepis occidentalis or C. monticola in their lineage (E. B. Babcock 1947).
