Crepis barbigera Leib. ex Coville

Crepis barbigera is recognized by its relatively tall stature, deeply pinnately lobed leaves, tomentulose stems, and phyllaries with coarse, green, eglandular setae. It is a complex of polyploid, apomictic forms, combining characteristics of C. atribarba, C. acuminata, and C. modocensis, from which the species is presumed to have been derived by intercrossing (E. B. Babcock 1947).

Perennials, 20–80 cm (taproots slender, caudices swollen). Stems 1–3(–5), erect, branched (branches strict with relatively few secondary branches), sparsely to densely tomentulose. Leaves basal and cauline; petiolate (petiole bases broadened, clasping); blades elliptic-lanceolate, 10–40 × 2–7 cm, margins deeply pinnately lobed (lobes mostly lanceolate or falcate, usually entire, rarely with 1–2 teeth), apices attentuate, faces tomentose or glabrate, sometimes setose. Heads 15–20+, in congested, corymbiform arrays. Calyculi of 5–7, lanceolate, green-setose bractlets 2–5 mm. Involucres cylindric, 9–17 × 4–7 mm. Phyllaries 6–10, lanceolate, 12–15 mm (margins yellowish, scarious), apices acute, abaxial faces tomentulose and coarsely green-setose, adaxial glabrous or with fine hairs. Florets 8–25; corollas yellow, 18–20 mm. Cypselae dark brown to olive, subcylindric, 8–9 mm, apices tapered, ribs 10–12 (strong); pappi whitish or yellowish white, 6–9 mm. 2n = 44, 55, 88.

Crepis barbigera is a North American species of flowering plant in the family Asteraceae. It is native to the northwestern United States. It has been found in Washington, Oregon, and Idaho.

Crepis barbigera is a perennial herb up to 80 cm (32 inches) tall, with a slender taproot and expanded woody caudex. One plant can produce as many as 20 small flower heads, each with up to 25 yellow ray florets but no disc florets. Flowers bloom May to July. It grows in a variety of habitats including open rocky places, foothills, plains, and sandy slopes.
