Shrub c. 1-2.5 m tall, with branches spreading to subpendulous. Stems orange-red, 4-lined and ancipitous when young, soon 2-lined, sometimes becoming terete; internodes 10-31 mm long, shorter than leaves; bark reddish-brown. Leaves petiolate, with petiole 1-2 mm long; lamina 20-55 x 10-22 mm, oblong-lanceolate or lanceolate to narrowly ovate, acute to obtuse or rounded-apiculate, margin plane, base cuneate to rounded, paler or sometimes ± densely glaucous beneath, chartaceous; venation: 4(5) pairs main laterals, with midrib branching ± obscurely distally, without visible tertiary reticulum; laminar glands dots and short streaks, ventral glands dense. Inflorescence 1-14-flowered, lax, with branches slender, from terminal node; pedicels 10-15 mm long; bracts narrowly lanceolate, deciduous. Flowers 25-40 mm in diam., stellate; buds ± broadly ovoid, apiculate to shortly acuminate. Sepals 8-13 x 2-5 mm, free, imbricate or open at base, equal, widely spreading to subrecurved in bud and fruit, ± narrowly lanceolate, acute, with margin entire (reddish) midrib conspicuous, veins not prominent; laminar glands linear c. 10. Petals golden yellow, sometimes tinged red, spreading to shallowly incurved, 12-20 x 8-14 mm, c. 1.5 x sepals, obovate, with apiculus subterminal, acute, margin entire or minutely denticulate towards apex. Stamen fascicles each with 30-55 stamens, longest 10-13 mm long, c. 0.6 x petals; anthers golden yellow. Ovary 4-6 x 3-4 mm, ovoid-conic to ovoid; styles 6-9-5 mm long, 1.2-1.5 x ovary, usually flexuous and ± twisted: stigmas scarcely capitate. Capsule 10-15 x 6-8 mm, ovoid.
