Shrub up to c. 1.5 m tall, bushy, with main branches erect and laterals widely spreading. Stems 2-4-lined when young, soon terete; internodes 20-50 mm long, shorter than leaves. Leaves petiolate, with petiole 1.5-2.5 mm long; lamina 35-70 x (10-)14-22 mm, lanceolate, apiculate-obtuse to rounded, margin plane, base broadly to narrowly cuneate, paler beneath, not glaucous, chartaceous; venation: 3 pairs main laterals without or with lax tertiary venation; laminar glands long streaks to dots; ventral glands absent. Inflorescence 1-4-flowered, from apical node; pedicels 5-10 mm long; bracts linear-elliptic. Flowers c. 30-35 mm in diam., ± deeply cyathiform; buds ovoid-subglobose, broadly obtuse to rounded. Sepals 10-11 x 4.5-5.0 mm, free not imbricate, subequal, erect in bud, erect to spreading in fruit, oblong to elliptic or oblanceolate-spathulate, apiculate-obtuse to rounded, with margin entire or finely eroded-denticulate, midrib and veins not prominent; laminar glands all linear or distally punctiform, numerous. Petals golden yellow, not red-tinged, rounded, markedly incurved, 15-20 x 10-15 mm, 2.0-2.5 x sepals, broadly obovate, with apiculus subterminal, rounded; margin entire, eglandular. Stamen fascicles each with c. 70 stamens, longest c. 8-9 mm, c. 0.8 x ovary, free, spreading-outcurved. Capsule 18-23 x 10-12 mm, narrowly cylindric-ellipsoid to ± broadly ellipsoid.
