Suffrutex 0.35-0.82 m tall, with stems solitary or few, usually slender, erect from ascending or creeping, branching and rooting base, unbranched below inflorescence. Stems shallowly 4-lined below nodes, sometimes 2-lined below or becoming almost terete, eglandular; internodes (30-) 45-105 mm, shorter than or equalling leaves. Leaves sessile or with petiole to 1.5 mm; lamina 44-110 ´ 18-50 mm, oblong or oblong-triangular to broadly ovate, rather paler beneath, not glaucous, plane, thinly chartaceous; apex obtuse to shortly apiculate or rounded, margin entire, base cordate-amplexicaul to truncate; venation: 4-7 pairs of main lateral veins from lower half of midrib, tertiary reticulation dense, prominent below; laminar glands very small, striiform to punctiform; intramarginal glands dense. Inflorescence (1-)5-13-flowered, from 1-2 nodes, rarely with flowering branches from one node below, the whole laxly corymbiform; pedicels (3-)10-50 mm; bracts and bracteoles 7-17 mm long, linear-lanceolate to linear-elliptic. Flowers 40-80 mm in diam., stellate, with petals becoming reflexed, tardily deciduous; buds narrowly ovoid, ± acute. Sepals 5, free or to 0.25 united, slightly imbricate, 3-5(-7) ´ 1.5-3(-5) mm, ovate to triangular-ovate, obtuse to acute, entire or occasionally minutely irregularly glandular-ciliate, erect to suberect in bud and fruit; veins 5, branched; laminar glands linear (inner) or interrupted (outer); marginal glands reddish or absent. Petals 5, golden? yellow, 25-40 ´ 7-10(-15) mm, 6-8 ´ sepals, oblanceolate, without apiculus, margin entire; laminar glands linear to distally striiform. Stamen fascicles 5, each with c. 45-60 stamens, longest 15-25 mm long, 0.5-0.65 ´ petals; anthers yellow, gland amber. Ovary incompletely 5-locular, 4-6(-7) ´ 3.5-4.5 mm, ± broadly ovoid; styles 5, 13-17 mm, 2.3-4.5 ´ ovary, slender, united almost to apices; stigmas small. Capsule 9-16 ´ 6-11 mm, broadly to narrowly ovoid or ovoid-conic, 3-4 ´ sepals, evittate. Seeds dark reddish brown, 1.1-1.5 mm, cylindric, without terminal appendage, very shallowly carinate; testa densely shallowly reticulate.
