Shrub 0-3-1 m tall, with branches suberect to spreading. Stems purplish-red, 4-lined but scarcely ancipitous when young, soon 2-lined, eventually terete; internodes 10-40(-60) mm long, shorter than to exceeding leaves; bark reddish-brown. Leaves petiolate, with petiole 1-1.5 mm long; lamina 30-60 x 9-30 mm, oblong- lanceolate or lanceolate to triangular-lanceolate, acute to rounded, margin plane, base cuneate to rounded, paler or sometimes ± densely glaucous beneath, chartaceous; venation: 3-4 pairs main laterals, with midrib branching distally, without visible tertiary reticulum; laminar glands dots and short streaks, ventral glands usually sparse or absent. Inflorescence 1-11-flowered, lax, with branches relatively stout, from 1-3 nodes; pedicels 13-30 mm long; bracts foliaceous, gradually reduced in successive nodes, deciduous. Flowers 30-55 mm in diam., ± stellate to subcyathiform; buds narrowly to broadly ovoid, acute to apiculate or subacuminate. Sepals 8-11 x 3-4 mm, free, imbricate, unequal or equal, outcurved to widely spreading in bud, widely spreading to recurved in fruit, lanceolate to ovate or oblong-ovate, acute to subacuminate, with margin entire (reddish); midrib conspicuous, veins not prominent; laminar glands c. 10. Petals golden yellow, not tinged red, spreading to shallowly incurved, 17-28 x 13-18 mm, c. 2-2.5 x sepals, oblong-obovate, with apiculus subterminal to lateral, acute to obtuse, margin entire. Stamen fascicles each with c. 45-50 stamens, longest 11-16 mm long, c. 0.6 x petals; anthers golden yellow. Ovary 5-6.5 x 3-5.5 mm, ovoid; styles 5-7 mm long, 1-1.2 x ovary, outcurved distally, not twisted; stigmas scarcely capitate. Capsule 13-17 x 8-10 mm, ovoid. Seeds dark red-brown, 1-1.3 mm long, narrowly cylindric, not or incompletely carinate, shallowly and loosely reticulate.
