Perennial herb, 0.05–0.11 m tall or long, glabrous, with stems erect to ascending from ± woody caespitose base, rooting and branching. Stems 2-lined, green, eglandular; internodes 5–15(–20) mm, shorter than to exceeding leaves. Leaves petiolate, thinly coriaceous, ± glaucous, 4–11 × 4–8 mm, broadly oblong-ovate to circular, apex rounded, margin plane to slightly indurated, base rounded, with pairs of ascending lateral veins; laminar glands pale, distal, punctiform, few or absent; intramarginal glands pale, spaced, conspicuous and one black, apical. Inflorescence 3–c. 21-flowered, from 1–2 nodes, subcorymbiform, rather dense, with lateral branches ascending; ‘cymules’ 1–5-flowered, branching monochasial, without flowering branches below; bracts and bracteoles elliptic, black-glandular-ciliate. Flowers 10–15 mm in diam., petals erect after flowering; buds cylindric-globose, rounded. Sepals subequal to equal, 2.5–5 × 1–1.5 mm, elliptic to narrowly oblong, obtuse to rounded; veins 3; margin black-glandular-denticulate. Petals bright yellow, tinged red in bud, 5–7 × 3.5 mm, 2–2.5 × sepals, oblong; marginal glands apical, few, black, on cilia; laminar glands pale, striiform. Stamens 15–23, longest 4-7 mm, 0.9–1 × petals. Ovary c. 2 × 1 mm, narrowly ovoid; styles not seen. Capsule 4–5 × c. 1.5 mm, narrowly ovoid. Seeds ‘dark-coloured’ (fide Stef., 1931), shallowly rugulose.
