Description

Herbs usually 8–25 cm tall, perennial. Rootstock ca. 8 mm in diam. Caudex woody, with dark brown or pale yellow scarious leaf sheath residues. Stems solitary or few, branched from base or from middle with curved-erect branches, stellate puberulent, basally leafy. Basal leaves narrowly elliptic to narrowly lanceolate, 5–20 × 0.4–0.7[–2] cm, stellate puberulent, glabrescent, base attenuate, margin mostly undulate, apex acuminate. Stem leaves few, smaller than basal leaves but otherwise similar. Synflorescence laxly corymbiform, with usually 2–4 long-pedunculate capitula. Involucre cylindric, 1.5–2 × 0.5–0.8 cm at anthesis, to usually 2.5–3 × 1–1.3 cm in fruit. Phyllaries stellate puberulent, glabrescent; outermost phyllaries triangular-ovate, 3–8 × 4–5 mm. Florets yellow, ca. 1.5 × as long as involucre. Achene cylindric, 1–1.4 cm, with tuberculate ribs, glabrous. Pappus dirty white to straw-colored, usually 1.5–2 cm. Fl. and fr. May–Aug. 2n = 14.

Perennial. Plant weakly pubescent, sometimes glabrescent. Root collar covered with indurescent brown or stramineous sheaths of basal leaves. Stems 10-25(35) cm high, pubescent, mostly branched from base or middle; branches curved, flexuous, terminating in solitary capitula. Basal leaves broadly lanceolate, hard, curved, with many veins, margin cartilaginous, usually undulate and scabrous, pubescent with branched hairs or almost glabrous, narrowed at base into petiole; cauline leaves sessile; semiamplexicaul, narrower than basal leaves, undulate along margin, gradually reduced above. Capitula 2-4(10), long cylindrical, 2-2.5(3) cm long and 0.5-0.8(1) cm wide (at flowering), broader at fruiting, terminal on branches. Involucre pubescent; bracts coriaceous, outer bracts deltoid-ovate, somewhat acuminate; inner bracts oblong-lanceolate, narrowly membranous along margin, more or less acuminate or subobtuse, several times as long as outer. Ligulate florets yellow, one and one-half to two times as long as involucre. Mature achenes terete, 10-15 mm long, glabrous, ribbed, somewhat acerate along ribs, sometimes only in upper part scabrous; pappus dirty white, its bristles plumose, longer of them barbed above; crown of hairs at articulation of pappus with achene.
