Erect shrub, 0.15-1 m, branches strict, creeping and rooting at the base; branchlets 2-lined when young, eventually terete. Leaves sessile, 4-9 by 1-3 mm, ovate-lanceolate to elliptic or narrowly elliptic-oblong, apex subacute to rounded, base cuneate, concolorous, plane or ± carinate, ± imbricate-appressed; c. 6 main lateral veins, ± parallel, not visibly branching, uniting near margin and apex, without visible reticulate venation; laminar glands pale, linear, becoming ± interrupted or punctate towards margin; intramarginal glands pale or black. Inflorescence 1-flowered, without shoots in uppermost axils, branching farther down stem; pedicels usually shorter than uppermost leaves, 2-6(-10) mm in fruit. Flowers 2-2½ cm ø, ± plane; buds narrowly ovoid, subacute. Sepals 3-6½ by ¾-2½ mm, free, not imbricate, elliptic to linear-lanceolate, subacute to obtuse or rarely rounded, entire; laminar glands pale, linear to punctate; submarginal glands pale or black. Petals dark yellow to pale yellow, sometimes red-tinged below, 7-15 by 3-6 mm, oblanceolate, entire, persistent; apiculus absent or almost so; laminar glands pale, linear, sometimes interrupted distally; submarginal glands absent. Stamens obscurely 3-fascicled, c. 17-24, longest 5-8 mm, c.¾ as long as petals, persistent; anthers bright yellow, gland amber. Ovary 2 mm, ovoid; styles 3(-4), 2 mm, equalling ovary, divergent; stigmas not capitate; placentas 3 (4) axile. Capsule 6-8 by 3-4 mm, ovoid, longitudinally vittate.
