Vouchers of
CHINA. Anhui Province: Jinzhai County, Tianma National Nature Reserve, growing at margins of mountain roads, elevation ca. 1165 m, 1 June 2009 (fl.), Kun Liu 2009042 (holotype: ANUB!; isotypes: ANUB!, IBK!).
Herbs perennial, 15–45 cm tall. Stems often many, erect or arcuate at base, terete, simple or short branched, with tangled multicellular hairs. Leaves alternate, occasionally opposite on lower part; petiole 3–25 mm, broadly winged, base auriculate on leaves from middle and lower part of stems and branches. Leaf blades ovate to ovate-elliptic, rarely ovate-lanceolate, 1.5–5.5 × 1.0–3.5 cm, abaxially multicellular hairs, brown patches, adaxially pubescent, base broadly cuneate to subrounded, apex acute to subobtuse; veins 2 or 3 pairs, inconspicuous. Flowers solitary, in axils of apically diminished leaves, often in shortened, nearly capitate inflorescences at apex of stems and branches. Pedicel densely covered with multicellular hairs; lowest pedicels 2–3 cm, gradually reduced in length in upper flowers, recurved in fruit. Calyx lobes ovate-lanceolate, 6–7 × 1–1.4 mm, abaxially sparsely pubescent. Corolla yellow; tube 0.5–1 mm; lobes ovate or rhomboid-ovate, 8–11 × 5–7.5 mm, transparent glandular. Filaments connate basally into a 0.5–1 mm high ring, free parts 2.5–3 mm; anthers dorsifixed, opening by lateral slits. Ovary pubescent; style 5–6 mm. Capsule subglobose, 3.5–5 mm in diam. Fl. Apr–Jun.
