Crepis tibetica Babcock.

Herbs, perennial, with a horizontal or oblique rhizome. Stem solitary to few, 25-65 cm tall, erect, unbranched or moderately branched from basal third or higher up, with conspicuously erect and usually rather long branches, apically ± densely with blackish long glandular hairs. Leaves mostly basal, rosulate to crowded, oblanceolate to elliptic, (3-)5-16(-22) × 0.8-2.2 cm including a winged petiole 1/3-1/2 rest of leaf, both faces with long yellowish hairs, base cuneate-attenuate to abruptly narrowed, margin sinuate-dentate to pinnatifid with triangular segments, apex obtuse to rounded. Stem leaves 0-2, similar to basal leaves or bractlike and reduced, ± linear, margin entire. Synflorescence corymbiform to paniculately corymbiform, with (1-)3-12 capitula. Capitula with 30-40 florets; peduncle slender, 0.5-5 cm, sparsely to more densely white tomentose and with ± dense blackish glandular hairs. Involucre green to dark green, cylindric to campanulate, 7-11 × 3-5 mm. Phyllaries abaxially sparsely arachnoid hairy and with blackish glandular hairs along midvein; outer phyllaries triangular-ovate to lanceolate, longest to 1/2 (sometimes even more) as long as inner ones, apex acuminate to acute; inner phyllaries 12-14, apex acuminate. Anther tube 2-2.5 mm. Style branches dark (± blackish when dry). Achene ± dark brown, fusiform, 4-5 mm, with 10 ribs, distinctly attenuate toward apex. Pappus white, ca. 4 mm. Fl. and fr. Jun-Aug.

Mountain slopes, thickets, forests, forest margins, meadows; 2600-4200 m. W Sichuan (Kangding), Xizang, Yunnan [Bhutan, NE India, Nepal].

Babcock’s names Crepis elongata and C. tibetica are of equal priority. The first synonymization of the latter with the former name in FRPS (80(1): 114. 1997) has therefore established the priority of C. elongata over C. tibetica.
