少花黄鹌菜 shao hua huang an cai

Crepis szechuanica E. S. Söderberg, Svensk Bot. Tidskr. 28: 362. 1934, based on C. scaposa C. C. Chang, Sinensia 3: 201. 1933, not R. E. Fries (1928); Hieracium runcinatifolium C. C. Chang, nom. illeg. superfl.; Youngia scaposa Babcock & Stebbins, nom. illeg. superfl.

Herbs 15-40 cm tall, perennial, rosulate. Caudex brown lanate, with residues of old leaf bases. Stems solitary or few, slender, erect, branched from base or higher, leafless or only with bracts. Rosette leaves oblanceolate, to 20 × 7 cm, lyrately pinnatilobate, pinnatipartite, or pinnatisect, both faces pubescent with brown multicellular crinkled hairs, base attenuate into a petiole-like portion, margin mucronately sinuate-dentate; lateral lobes 5-8 pairs, opposite or alternate, semiorbicular, elliptic, or triangular, gradually smaller toward leaf base, apex obtuse to rounded; terminal lobe ovate, 5-10 cm, much larger than lateral lobes, shallowly lobed, apex rounded. Synflorescence paniculiform-corymbiform, with numerous capitula. Capitula with ca. 5 florets; peduncle very slender. Involucre cylindric, 6-7 mm. Phyllaries abaxially glabrous; outer phyllaries ovate to lanceolate, longest ca. 1.5 mm, apex ± acute; inner phyllaries 5, adaxially glabrous, apex obtuse. Anther tube and style branches yellow upon drying. Achene dark purplish brown, subfusiform to columnar, 2-3 mm, apex slightly attenuate. Pappus yellowish brown, 3-4 mm. Fl. and fr. Jun-Jul.

● Trailsides on mountain slopes; 900-1700 m. Sichuan.

Crepis szechuanica (1934), Hieracium runcinatifolium (1935), and Youngia scaposa (1937) are all replacement names for the illegitimate later homonym C. scaposa C. C. Chang. The earliest legitimate name for the species is C. szechuanica, and the correct name in Youngia must therefore be Y. szechuanica. The taxonomic placement of the species in Youngia, however, needs confirmation.
