Dwarf shrub, 0.02–0.2 m tall, with stems slender, erect, branching strictly from stout woody rooting and branching rootstock, without axillary shoots. Stems 4-lined, eglandular; internodes 1–5 mm, shorter than leaves to exceeding them below inflorescence. Leaves 4-verticillate, densely imbricate, sessile, deciduous, papillose above, wholly glaucous, 1–5(–6.5) × 0.5–0.8 mm, linear to narrowly triangular-lanceolate, apex mucronulate to apiculate, margin revolute, base rounded, 1-veined; laminar glands pale, scattered, sometimes sunken, punctiform; intramarginal glands not seen. Inflorescence 1–16-flowered from 1–3 nodes, rather dense, elongating in fruit, subcorymbiform, 5–15 mm long, sometimes with subsidiary branches from 1–2 nodes below; bracts and bracteoles whorled below, upper ones spiral, narrowly triangular-lanceolate, long-curved-acuminate, with black-glandular-ciliate auricles, margin plane, eglandular or with 1–2 sessile black glands towards base, apex with small pale or reddish gland. Flowers c. 8–10 mm in diam.; buds ellipsoid, obtuse. Sepals equal, free, not or scarcely imbricate, (1.5–)2–3(–4) × 0.8–1.3 mm, c. 2 × sepals, lanceolate to narrowly or broadly elliptic or obovate, acuminate to obtuse; veins 3, prominent; margin almost entire to regularly black-glandular with glands sessile or on denticles or cilia, obconic to globose; laminar glands pale, linear, distally interrupted. Petals yellow, not tinged red, persistent, 4–7 × 1.5–2.5 mm, oblong-elliptic; marginal glands few, small, black, apical, on cilia; laminar glands pale, linear to striiform. Stamens 30–35, longest 3–6 mm, persistent. Ovary c. 1–2.5 × 0.5–1.5 mm, ovoid to ovoid-conic; styles 3–3.5 mm, 1.5–3 × ovary. Capsule 2–4 × 2–3 mm, ovoid to ellipsoid; valves narrowly longitudinally vittate. Seeds yellow-brown, 0.7–1.2 mm long, curved, papillose?
