Shrub 0-9-3 m tall, deciduous, with branches erect. Stems dark reddish-brown, 2-lined and subancipitous when young, soon terete; internodes 20-35 mm long, shorter than leaves; bark reddish-brown. Leaves sessile, amplexicaul; lamina (40-)45-117 x (27-)37-60 mm, ovate-oblong to ovate, obtuse-apiculate (or rarely acute) to rounded, margin plane, base cordate, not or scarcely paler beneath, not glaucous, chartaceous; venation: (6-)7-8(-9) pairs main laterals, branched, the midrib pinnately branched, with tertiary reticulum very dense, prominent on both sides or beneath only; laminar glands punctiform, large and small in the reticular areolae; ventral glands absent. Inflorescence 5-20-flowered, from apical node, subcorymbiform, sometimes also from second node and on lower short lateral shoots, the whole then pyramidal; pedicels 8-20 mm long; bracts small, lanceolate, deciduous. Flowers c. 35 mm in diam., stellate; buds conic, acute. Sepals 2-5-5 x 1.5-2 mm, free, imbricate, subequal, erect to outcurved in bud, ± spreading in fruit, ovate to lanceolate or oblong-elliptic, acute, sometimes apiculate, with apex incrassate, margin entire, midrib distinct or not, other veins not prominent; laminar glands few, striiform to punctiform. Petals golden yellow, not tinged red, spreading, (13-)15-20 x 6-10 mm, 5-6 x sepals, obovate to oblanceolate, with apiculus lateral, acute; margin entire, eglandular. Stamen fascicles each with 20-35 stamens, longest (8-)12-15 mm, 0.7-0.8 x petals; anthers yellow. Ovary 4-5 x 2-5 mm, narrowly ovoid to ovoid-ellipsoid; styles 8-10 mm long, 1.4-2 x ovary, free but sometimes coherent in lower half, erect, apically sometimes slightly spreading; stigmas subcapitate. Capsule 9-10 x 7 mm, narrowly ovoid to ellipsoid. Seeds dark reddish-brown, c. 0.9 mm long, cylindric, narrowly carinate, linear-foveolate to ribbed-scalariform.
