Shrub 0-5-1 m tall (or taller?), bushy (?) with branches erect or ± spreading. Stems 4-lined and ancipitous when young, soon 2-lined, eventually terete; internodes 1- 3 mm long, shorter than leaves; bark fissuring. Leaves sessile or subsessile, sometimes amplexicaul; lamina 35-60 x 10-32 mm, ± narrowly ovate to triangular-lanceolate, obtuse (or rarely acute) to rounded, margin plane, base rounded or more rarely cordate, slightly paler beneath, not glaucous, papyraceous; venation: 4-5 pairs ascending main lateral veins, with tertiary reticulum prominent on both sides; laminar glands small; intramarginal glands dense. Inflorescence 1-9-flowered, from 1-2 nodes with condensed internode, subcorymbiform to pseudo-umbellate with branches ± narrowly ascending, without accessory flowers, sometimes with 1-3- flowered branches from node below; pedicels 7-12 mm long; bracts reduced, linear-lanceolate to linear-subulate. Flowers (20-)25-30(-35) mm in diam.; buds ellipsoid-subglobose, rounded. Sepals (2-)3-6(-7) x 1.5- 2.5(-4) mm, imbricate, unequal to subequal, spreading to subdeflexed and enlarging after anthesis, deflexed and persistent in fruit, triangular-lanceolate or lanceolate to oblong-elliptic, acute to obtuse, 5-7-veined from base with veins sometimes ± branched and reticulate; laminar glands linear and punctiform; intramarginal glands dense. Petals golden yellow, not red-tinged, spreading, (10-)12-18 x 5-8 mm, 3-4 x sepals, oblan- ceolate, with apiculus rounded or obsolete. Stamen fascicles each with 20-30 stamens, longest 12-18 mm, equalling or slightly exceeding petals. Ovary 4-5(-6) x 3-4.5(-5) mm, broadly ovoid to subglobose, acute to obtuse; styles 5-10 mm long, 1.5-2.5 x ovary, erect to suberect, narrowly divergent near apex, slender; stigmas narrowly capitate. Capsule 8-13 x 7-10 mm, ± broadly cylindric-ellipsoid, acute to obtuse, chartaceous, somewhat fleshy at first, soon drying, tardily and sometimes incompletely dehiscent. Seeds yellowish-brown, 1.2-1.5 mm long, unilaterally winged with terminal winged appendages.
