Leaves: radical, simple, seldom auriculate, green, petiolate, patent-erect; lamina rigid, coriaceous, ovate to elliptic, 26-45(-60) x 15-35 mm, apex obtuse, base varies from truncate to narrowly cuneate, margin irregularly bicrenate, adaxially and abaxially covered with appressed non-glandular hairs, margins inconspicuously ciliate with short appressed hairs; petiole thin, 25-90 mm long, patent, green, hirsute with appressed curly hairs interspersed with coarse appressed non-glandular hairs; stipules 6-15 mm long, subulate, adnate to petiole, apices free, ciliate. Inflorescence: scape 25-100 mm long, branched, bearing 2-5 pseudo-umbellets with 2-8 flowers each; peduncles 40-100 mm long, 1 mm in diameter, reddish green, covered with distally appressed curly hairs, interspersed with short and long glandular hairs; bracts subulate, 3-5 mm long, abaxially hirsute. Pedicel ca. 0.5 mm long. Hypanthium (18-)25-38 mm long, 3-5 times the length of the sepals, reddish green, densely covered with distally appressed curly hairs, interspersed with short and long glandular hairs. Sepals 5, posterior one erect, others patent, 6-8 mm long, 1.5-2.5 mm wide, linear-lanceolate, apices subulate, reddish green in centre with green membrane-like margins, abaxially covered with appressed curly hairs, interspersed with long glandular hairs. Petals 5, yellow, narrowly spathulate, patent, flower bell-shaped during anthesis; posterior two with dark red blotches and feather-like markings, 17-22 x 3-5.5 mm, length/width ratio 4-7, apices rounded, truncate to emarginate; anterior three 16-20 x 2-4 mm, apices rounded. Stamens 10, staminal column 1 mm long, smooth, white; perfect stamens 5, concealed within the floral sheath, posterior one 2-3 mm long, lateral two 3-4 mm long, anterior two 5-6 mm long, shorter than the sepals, white; anthers 1.5-2 mm long, wine-red, pollen orange. Gynoecium: ovary 2-3 mm long; style filiform, 0.5-1.5 mm long; stigma branches patent, 1-1.5 mm long, dark pink. Fruit: bases of mericarps 5 mm long, with glandular hairs, tails 22 mm long.
