Morphological description
Herbs, perennial, 0.2–0.5 m tall. The procumbent rhizomes over the ground are long and fragile. The stems are procumbent or pendulous and ascendant at anthesis, solitary, unbranched or rarely 1– or 2–branched, densely pubescent and then becoming sparsely pubescent. The leaves are crowded at stem apex during the vegetative period, and the lower and middle stem leaves are usually withered at anthesis. Middle stem leaves: petiole 1–2.5 cm; leaf blade broadly to triangularly ovate, 2.5–3.5×2–3 cm, olive, abaxially sparsely appressed pubescent or glabrescent, adaxially sparsely pubescent, grayish green, pinnatifid or inconspicuously divided, and cuneate toward the base. The leaf margins extend downward along the petiole. The distal stem leaves are sessile or subsessile, gradually smaller, and coarsely toothed or lyrate-pinnatipartite. The capitula are solitary, rarely comprised of two, and 2.5–4 cm in diameter. The involucres are cup-shaped; phyllaries in four rows, abaxially densely appressed pubescent, carious margin white, outer ones leaflike, herbaceous, elliptical, coarsely toothed, 0.8–1.2 cm, middle and inner ones linear-lanceolate, or elliptical, 6–8 mm. Ray floret lamina white, approximately 1.4 cm. Achenes approximately 1.5 mm.
Habitat: on rocky cliffs or sometimes in rocky mountain slopes at elevations of 800–1,480 m.
Distribution: western Hunan, China.
