Crepis bakeri

Perennials, 10-30 cm (taproots thick, caudices swollen, often covered by old leaf bases). Stems 1-3, erect (often reddish), stout, mostly simple, sparsely to densely tomentose, often stipitate-gland-ular proximally. Leaves basal and cauline; petiolate (at least basal); blades elliptic, runcinate, 8-20 × 2-5 cm, margins pinnately lobed (lobes broadly lanceolate, coarsely dentate, midribs often reddish), apices acute, faces sparsely to densely tomentose, stipitate-glandular. Heads 2-22 (1-3 per branch), in cymiform arrays. Calyculi of 8-10, deltate or lanceolate, tomentose bractlets 3-8 mm. Involucres cylindric, 11-21 × 5-15 mm. Phyllaries 10-14, lanceolate, 10-14 mm (margins yellowish), apices acute, abaxial faces glabrous or ± tomentose, sometimes setose and stipitate-glandular, adaxial glabrous or with fine hairs. Florets 11-40; corollas yellow, 16-20 mm. Cypselae dark or pale brown to yellowish, fusiform, 6-11 mm, apices ± tapered, ribs 10-13; pappi whitish, 6-13 mm. 2n = 22, 33, 44, 55.

Crepis bakeri is generally recognized by the low stature, dense rosettes of pinnately lobed leaves with coarsely dentate lobes, tomentose stems and leaves, stipitate-glandular hairs distally on stems, relatively large involucres, and densely flowered heads. It is considered closely related to C. occidentalis. Three somewhat weakly defined subspecies were recognized by E. B. Babcock (1947).
