Shrub or shrublet 0.15-1.5 m tall, erect, bushy, with branches strict, nearly always lateral, creeping and rooting at the base. Stems 2-lined and ancipitous when young, eventually terete, eglandular. Leaves sessile; lamina 4-9 x 1-3 mm, ovate-lanceolate to elliptic or narrowly elliptic-oblong, concolorous, not glaucous, plane or incurved, imbricate-appressed to spreading; apex subacute to rounded, margin plane or undulate, base narrowly cuneate; venation: 3(4-7) pairs of main lateral veins, curved-parallel, not visibly branched except near apex and margin, without tertiary reticulation; laminar glands pale, linear towards base, interrupted or punctiform towards apex and margin; intramarginal glands dense, pale. Inflorescence 1- flowered, without or rarely with paired flowering branches in uppermost axils, with scattered flowering branches from lower nodes; pedicels 2-10(-20) mm in fruit. Flowers 20-25 mm in diam., stellate; buds narrowly ovoid, subacute. Sepals 3-6.5 x 0.75-3 mm, not imbricate, equal, elliptic to linear-lanceolate, subacute to obtuse or rarely rounded, entire; veins 7, outer ones branched; laminar glands pale, all linear or some interrupted to punctiform towards apex and margin; inframarginal glands pale. Petals dark to pale yellow, sometimes tinged red dorsally, 7-15 x 3-6 mm, c. 2-2.5 x sepals, obovate-elliptic, rounded, apiculus absent or almost so; laminar glands pale, linear, sometimes interrupted distally, marginal glands absent. Stamens not or obscurely 3(4?)-fascicled, c. 17-24, longest 5-8 mm, c. 0.6-0.8 x petals; anther gland amber. Ovary 2 x 1 mm, ovoid, acute; styles 3(4), 1.5-2.5 mm long, 0.8-1.2 x ovary, divergent; stigmas not capitate; placentae 3(4), axile. Capsule 6-8 x 3-4 mm, c. 1.3-2 x sepals, ovoid, with valves longitudinally vittate. Seeds yellow-brown, c. 0.8 mm long, scarcely carinate; testa densely linear-foveolate.
