Shrub 0.3-1.2 m tall, with branches spreading to pendulous. Stems yellow-brown (young parts purplish at first), 4-lined when young, soon terete, slender, internodes 10-25 mm long, shorter than leaves; bark grey-brown. Leaves petiolate, with petiole 0.5-1 mm long; lamina 20-40 x 8-20 mm, triangular-lanceolate to triangular-ovate, acute or more rarely obtuse to rounded, margin plane, base rounded to shallowly cordate, ± glaucous beneath, chartaceous; venation: 3-4 pairs main laterals, branched, the midrib pinnately branched, with tertiary reticulum obscure or invisible; laminar glands streaks (occasionally elongate) and dots. Inflorescence 1(3)- flowered, from apical node; pedicels 6-10 mm long; bracts linear or usually foliar. Flowers 20-40 mm in diam., deeply cyathiform; buds ovoid, acute to apiculate. Sepals 8-14 x 3-5 mm, free, imbricate, unequal, outcurved or spreading and purplish in bud and fruit, ovate to lanceolate or narrowly elliptic or rarely foliaceous, subacute to acuminate or rarely apiculate-obtuse, margin entire, midrib narrow sometimes indistinct; laminar glands linear, interrupted distally. Petals deep yellow, markedly incurved, 12-22 x 8-17 mm, 1.1-1.5(-2) x sepals, broadly obovate to subcircular, with apiculus subterminal, obtuse to rounded; margin entire, eglandular. Stamen fascicles each with c. 60 stamens, longest 10-12 mm long, 0.35-0.7 x petals; anthers deep (?) yellow. Ovary 6-8 x 4.5-6 mm, ± broadly ovoid; styles 3-4 mm long, c. 0.5 x ovary, free, outcurved near apex; stigmas narrowly or scarcely capitate. Capsule (12)14-17 x 8-10 mm, ovoid-conic to broadly ovoid, with thickly coriaceous valves, turning cherry red at first. Seeds dark reddish-brown, 0.8-1 mm long, cylindric, not winged, not or scarcely carinate, shallowly linear-foveolate.
