Spreading perennial herb, woody at the base, to 1 m tall, to 0.4-0.5 m in diameter. Stems 9-12 mm in diameter at base, although with some pith even in larger stems, brittle, yellowish-green, sparsely to densely pubescent, the plants usually glutinous-viscose, the glandular trichomes always present, most frequently simple uniseriate 1-2-celled trichomes with a multicellular glandular head, , sparsely to densely pubescent with 6-8-celled uniseriate simple trichomes 1.5-2.5 mm long, these with a unicellular glandular head in some populations, both lamina surfaces with underlying velvety pubescence of uniseriate simple trichomes to 0.1 mm long.
Sympodial units 2-foliate; internodes 1-6 cm long.
Leaves interrupted imparipinnate to imparipinnate, (1.5-) 3.5-13 cm long, (1.2-) 2.2-7.5 cm wide, yellowish green, pubescent like the stems, adaxially almost glabrous in some populations, the trichomes only on the veins and margins, abaxially the pubescence more abundant but usually the same as that of the adaxial face; primary leaflets 2-4 pairs, broadly elliptical to orbicular, the base cordate, not markedly oblique, the margins irregularly crenate to occasionally almost entire, the apex rounded; terminal leaflet usually wider than long, 0.8-3 cm long, 0.8-4 cm wide, the petiolule 0.4-1.5 cm long; lateral leaflets 0.5-5 cm long, 0.4-4.5 cm wide, the petiolule 0.15-1 cm long; secondary leaflets absent; tertiary leaflets absent; interjected leaflets few or more usually absent; petiole 0.5-4 cm long; pseudostipules present and well developed on all nodes, 0.5-1 cm long, 0.7-1.5 cm wide, orbicular, the margins crenate.
Inflorescences 4-11 cm long, simple or once-branched, with 6-15 flowers, bracteate at all nodes, the bracts 0.2-1.5 cm long, 0.2-1.5 cm wide, the margins crenate, peduncle 1-4 (-7) cm long, pubescent like the stems and leaves. Pedicels 1-2 cm long, articulated at the base. Buds 0.8-1 cm long, 0.4-0.5 cm wide, elongate ellipsoidal, strongly curved, with the corolla exserted more than halfway from the calyx just before anthesis.
. Flowers with the calyx tube ca. 0.5 cm long, the lobes 0.4-0.5 cm long, 0.1-0.15 cm wide, triangular to spathulate, pubescent like the rest of the inflorescence, the apex rounded; corolla 2-2.1 cm in diameter, pentagonal and slightly zygomorphic with the upper petal longer, golden yellow, the tube 0.7-0.8 cm long, the lobes 0.6-0.7(-1) cm long, 0.5-0.6(-0.9) cm wide, densely pubescent abaxially with weak uniseriate trichomes, these more abundant on the midveins and lobe tips, the lobes slightly reflexed at anthesis; staminal column absent or only partially coherent with lateral papillae, strongly curved, the filaments less than 0.5 mm long, united into a tube ca. 1 mm long, the anthers 0.6-0.8(-1) cm long, the upper two usually larger and the anther tube curved, the sterile apical appendage absent, the tips of the anthers with a minute deltate appendage distal to the introrse pores; ovary globose, glabrous; style 0.9-1 cm long, ca. 0.5 mm in diameter, curved, finely pubescent in the basal 3/4, exserted 2-3 mm beyond the anthers; stigma large capitate or slightly bifid, green.
Fruit 1-1.3 cm in diameter, globose, 2-locular, green, sparsely to moderately pubescent with uniseriate simple trichomes with 4-celled and 1-celled glandular tips and eglandular trichomes ca. 0.5 mm long; fruiting pedicels 2-2.5 cm long, straight or slightly bent at the articulation; calyx lobes in fruit 0.9-1 cm long, 0.2-0.5 cm wide, spreading.
Seeds 1.4-2.4 mm long, 0.7-1.2 mm wide, 0.5-0.6 mm thick, obovate, pale brown, pubescent with hair-like outgrowths of the lateral testa cell walls, which give a silky appearance to the surface, narrowly winged (0.2 mm wide) at the apex and acute at the base.
