形态特征：Herb perennial, glabrous totally. Stolons elongate, creeping. Stems erect, 20‒35 cm tall, slender, with sparse branches from base. Basal leaves crowed, present at anthesis, dimorphic; blades of early ones nearly orbicular to long-elliptic, 0.9‒2.5 cm long, 0.7‒1.3 cm wide, apex obtuse and mucronate, base broadly cuneate to rounded, margin entire and with sparsely slender ciliate-teeth, with petioles 1‒3 cm long; blades of later ones narrowly elliptic to lanceolate, 3‒6 cm long, 0.6‒1.1 cm wide, apex acute, base attenuate to a 2‒3 cm long petiole, margin entire or with sparsely slender ciliate-teeth below. Cauline leaves 1‒3; blades linear-lanceolate, 2.5‒7.5 cm long, 0.4‒0.7 cm wide, apex acuminate, base attenuate, margin entire and with/without sparsely slender ciliate-teeth below. Synflorescence corymbiform, with 6‒16 capitulae; capitula with 7‒10 florets, base with slender, long peduncle. Bracts small, broadly ovate-triangular, ca. 1 mm long, margin entire or with 1-pair ciliate-teeth. Involucre narrowly cylindrical, 8‒10 mm long. Phyllaries 2 series, abaxially glabrous; outer phyllaries broadly ovate, 0.5‒0.7 mm long, apex obtuse; inner phyllaries 8, linear-lanceolate, 7‒9 mm long, apex obtuse, short-ciliate. Receptacle flattened, glabrous, alveolate. Florets 7‒10, yellow, corolla 10‒11 mm long, tube 3‒3.5 mm long, ligule linear, apex 5-lobed. Achenes brown or pale brown, narrowly fusiform or linear-fusiform, slightly compressed, 4.5‒5 mm, finely spiculate, with ribs finely spiculate, apex attenuate to a 1‒1.5 mm long slender beak. Pappi pale brown, ca. 5 mm long, scabrid.
