Herbs, perennial, subscapigerous, rhizomatous. Stems usually solitary, erect, 30-60 cm tall, slender, simple or branching into synflorescence, pubescent especially near base or ± glabrous, subscapiform. Basal leaves present at anthesis, rosulate, shortly petiolate; petiole obscure, winged, basally expanded but not auriculate; blade elliptic or oblanceolate-elliptic, 5-21 × 2-5 cm, thickly papery, both surfaces sparsely pubescent to glabrous, pinnately veined, lateral veins 14-18, base cuneate or broadly attenuate into winged petiole, margin acutely shallowly sinuate-denticulate, apex obtuse. Median stem leaves few, sessile, oblong to linear, base expanded and subamplexicaul, margin denticulate, apex obtuse; uppermost leaves linear, bractiform. Capitula radiate, few to many in a rather lax terminal corymb or compound corymb, branches slender; peduncles 5-20 mm, slender, sparsely pubescent, linear-bracteate, with 2 or 3 linear bracteoles. Involucres narrowly campanulate, 3-4 × 2-4 mm, calyculate; bracts of calyculus 4 or 5, linear-subulate; phyllaries 10-13, oblong, ca. 1 mm wide, herbaceous, sparsely puberulent, margin broadly scarious, apically acute, dark and shortly bearded. Ray florets ca. 8; corolla tube ca. 3 mm; lamina yellow, oblong or elliptic-oblong, ca. 6.5 × 2 mm, 4-veined, apically obtuse, 3-denticulate. Disk florets ca. 25; corolla yellow, ca. 5 mm, with ca. 3 mm tube and fun-nelform limb; lobes ovate-lanceolate, ca. 1 mm, apically acute, papillose. Anthers ca. 1.6 mm, basally distinctly subacutely auriculate, appendages ovate-lanceolate; antheropodia rather small, basally slightly dilated. Style branches ca. 0.8 mm. Achenes cylindric, ca. 4 mm, pubescent. Fl. Apr-Jun.Both dry and wet meadows and pastures; 1500-3300 m. Guizhou, Sichuan, Yunnan [N Bangladesh, NE India, Myanmar, NE Thailand].
The apparent earlier homonym, "Senecio obtusatus Pursh" (Fl. Amer. Sept. 2: 530. 1813) was merely cited as a synonym and was therefore not validly published (Vienna Code, Art. 34.1(c)). The replacement name Senecio khasianus was therefore nomenclaturally superfluous when published and is consequently illegitimate (Art. 52.1).
