Shrub or small tree 0-5-2-5 m tall, dense and rounded or ± lax and elongate, with branches ± spreading. Stems red to orange, 4-lined and ancipitous when young, eventually terete; internodes 15-30 mm, shorter than leaves; bark grey-brown, smooth. Leaves petiolate, with petiole 1-2 mm long; lamina (bluish green fide Thomas, 1992) 25-80 x 10-37 mm, triangular-lanceolate to narrowly or rarely more broadly ovate, acute to apiculate-rounded, margin plane to recurved, base broadly cuneate to rounded, paler to glaucous beneath, chartaceous to subcoriaceous; venation: 3-4 pairs main laterals, the midrib pinnately branched, with lax tertiary reticulum; laminar glands short streaks and dots; ventral glands absent or ± dense. Inflorescence 1-3(-10 or very rarely -18)-flowered, from 1-2 nodes, subcorymbiform; pedicels 5-12 mm long; bracts linear, persistent. Flowers (35-)40-70 mm in diam., shallowly cyathiform; buds ± broadly ovoid, acute to subacute. Sepals 7-20 x 2-8 mm (to 22 x 8 mm in fruit), free, imbricate, unequal, spreading to recurved in bud and fruit, narrowly oblong or ± narrowly elliptic or rarely ovate to oblanceolate, acute to subacute, with margin entire; midrib sometimes visible below, visible and sometimes incrassate above, veins not prominent; laminar glands numerous, linear, interrupted towards apex. Petals deep golden yellow, not tinged red, slightly incurved, (20-)25-45 x 14-30 mm, c. 2-3 x sepals, broadly obovate to subcircular, with apiculus acute to obtuse, lateral, margin entire, eglandular. Stamen fascicles each with c. 80 stamens, longest 9-12 mm long, c. 0.35 x petals; anthers golden yellow. Ovary 6-9 x 4-5 mm, ± narrowly ovoid-conic to narrowly ellipsoid-acuminate; styles 3.5-7 mm long, 0.5-0.9 x ovary, free, ± sharply outcurved near apex; stigmas small. Capsule 10-20 x 8-10(-13) mm, narrowly ovoid-conic to narrowly ellipsoid. Seeds dark orange-brown to reddish-brown, 0.8-1 mm long, cylindric, scarcely carinate, shallowly linear-reticulate to linear-foveolate.
