Early vernal, delicate plants. Plant base usually with a “tunica” of brownish dry petioles. Leaves araneous or sparsely araneous deeply lobate, lobation pattern oftencomplicated, lobes patent or pointing downwards. Midrib without striatulate pattern, leaf blade unspotted. Petioles unwinged to narrowly winged. Scapes sparsely araneous or araneous, particularly below the capitulum. Involucre with rounded base, usually of medium width (ca. 7–10 mm wide). Flowers yellow, ligules flat. Pollen present (variable in size) or absent, stigma discoloured (usually pale greenish). Exterior and interior involucral bracts flat, without corniculation at the apex, rarely slightly callose. Exterior bracts 12–16, of ± equal length or slightly imbricate, adpressed, loosely adpressed to erect, or patent, lanceolate to ovate, usually 6–10 mm long, with broad paler margins, ciliate. Achenes usually pale greyish straw brown or red, densely spinulose above, 3.0–4.4 mm long, subabruptly or ± abruptly narrowing in the cone. Cone conical-subcylindrical or subcylindrical, 0.5–0.9 mm long. Rostrum thin, 6.0–9.0mm long. Pappus 5.0– 6.0mm long, white. Plants studied were found to be agamospermous.
