A densely tufted perennial bush 40-80 cm. high. Branches terete, 4-5 mm. thick, soft when young, becoming hard with age, shortly pubescent. Leaves petiolate; petioles 1.5-4 cm. long; lamina semi-orbicular or reniform, more or less cordate at the base, shallowly 5-lobed with the lobes 3-5-toothed or crenate, up to 4-5 cm. long, 5 cm. broad, fleshy and slightly folded upwards, very minutely glandular-hispid on both surfaces, and in addition sparsely covered with longer simple hairs, sometimes somewhat glaucous. Stipules broadly ovate to ovate-lanceolate, 5-13 mm. long, 4-7 mm. broad. Peduncles 4-20 cm. long, thinly and shortly pubescent, each bearing 4-20 flowers; bracts subtending the flowers about 6, similar to the stipules in shape, but smaller, soon deciduous. Flowers pedicellate; the pedicel 2.8-3 cm. long, with the fused nectariferous calyx-spur extending about 2.5 cm. of its length, shortly glandular pubescent. Sepals lanceolate or oblong lanceolate, acute, 1-1.2 cm. long. Petals salmon-pink, the upper two or all red-veined, subequal, the two upper ones slightly narrower than the rest, obovate-cuneate, subtruncate at the apex, 2.3-2.6 cm. long, 1.1-1.4 cm. broad. Stamens fertile 5, opposite the sepals and more or less equal to them in length; staminodes 5, opposite the petals, either all much shorter, or three short and two nearly equal to filaments. Ovary densely villous. Fruit 4-4-5 cm. long, the beak with spreading white or light grey-hairs.
