Shrub 0.45-l.2(-2.4) m tall, much branched, with branches spreading or drooping, sometimes straggling or semi-scandent. Stems red, 4-lined and ancipitous when young, soon terete; internodes 15-50 mm long, shorter than or rarely exceeding leaves; bark grey. Leaves sessile; lamina 30-93 x 10-42 mm, elliptic to oblong or ovate-oblong, obtuse or apiculate to rounded, margin plane, base cuneate to rounded, paler beneath, sometimes glaucous, chartaceous, lower ones eventually deciduous; venation: 3-4(5) pairs main laterals, branched, the midrib pinnately branched, with tertiary reticulum lax to dense, conspicuous; laminar glands short lines or streaks or dots in the reticular areolae; ventral glands dense to sparse. Inflorescence l-3(-8)-flowered, from apical node, corymbiform, sometimes also on short lateral shoots from up to c. 16 nodes towards base of current growth, then cylindric-ellipsoid; pedicels 4-20 mm long; bracts intermediate, persistent to small, lanceolate, deciduous. Flowers 35-65(-75) mm, in diam., stellate; buds ovoid, obtuse to rounded. Sepals 5-8 x 2.5-5 mm, free, imbricate, subequal to somewhat unequal, erect in bud, ± ascending in fruit, narrowly ovate to elliptic-oblong, acute to rounded, margin entire or sometimes minutely denticulate near apex; midrib obscure but apex sometimes incrassate, other veins not prominent; laminar glands numerous, linear. Petals bright yellow to bright yellow-orange, not tinged red, spreading, 20-30 x 10-16 mm, c. 4 x sepals, obovate to oblanceolate, with apiculus lateral, rounded, margin entire, eglandular. Stamen fascicles each with c. 30 stamens, longest 15-20 mm long, c. 0.7 x petals, anthers yellow. Ovary 4-7 x 3-5.5 mm, ovoid-pyramidal to broadly ovoid; styles 9-14 mm long, c. 2-3 x ovary, free, erect or slightly apically outcurved; stigmas small to subcapitate. Capsule 9-17 x 7-11 mm, ovoid to ovoid-conic. Seeds dark reddish-brown, 1-1.2 mm long, cylindric or cylindric-ovoid, narrowly carinate, very shallowly linear-foveolate to ribbed- scalariform.
