Shrub (0-6)1.2-2.4 m tall, bushy, with branches erect to ascending. Stems red, 4-lined and ancipitous when young, eventually terete; internodes 4-16 mm long, shorter than leaves; bark grey. Leaves sessile 4-ranked; lamina 7-45 x 3-18 mm, narrowly to broadly elliptic or oblong-elliptic, acute, margin plane, base cuneate to reflexed-auriculate, concolorous, not or scarcely glaucous, subcoriaceous to chartaceous, lower ones soon deciduous; venation: 3(4) pairs of main laterals, not or sparsely branched, the midrib pinnately branched, with tertiary reticulum lax and inconspicuous or rarely rather dense; laminar glands linear, between main lateral veins, or ± interrupted by reticulum to form streaks and dots; ventral glands absent. Inflorescence 1-3-flowered or, if flowers more (4-6) , then usually from two close nodes, rarely up to c. 10-flowered from apical node with flowering branches from second node: pedicel 7-20 mm long; bracts foliar but smaller, persistent. Flowers 40-60 mm in diam., stellate; buds broadly to narrowly conical, acute. Sepals 6-10(13) x 3-5 mm, free, imbricate, subequal, erect in bud and fruit, rather broadly to narrowly ovate or ovate-triangular, sharply acute to subacute, margin entire or very rarely subentire, midrib sometimes visible, often then incrassate above, other veins not prominent; laminar glands linear, numerous. Petals rich golden yellow, sometimes tinged red, spreading, 20-33 x 13-22 mm, c. 3 x sepals, narrowly obovate, with apiculus subterminal, acute to rounded; margin entire, eglandular. Stamen fascicles each with c. 40 stamens, longest 10-17 mm long, c. 0-5 x petals; anthers yellow. Ovary (4)5-6 x 3-4 mm, broadly ovoid to ovoid-pyramidal; styles (8)10-13 mm long, c.2-5 x ovary, free or loosely coherent, erect; stigmas small. Capsule (8)10-12(14) x 8-13 mm, broadly ovoid to narrowly ovoid-conic. Seeds dark reddish-brown, 2.2 mm long, cylindric, not winged, slightly carinate, finely linear-foveolate.
