Perennial herb, 0.03–0.11 m tall, glabrous, caespitose, erect to decumbent or creeping and budding from branching base, without basal sterile shoots. Stems scabrid with red-tipped glandular emergences dendroid towards base of stem, simple above, absent in upper part; internodes 3–10 mm, shorter than leaves. Leaves subsessile, ascending to erect, sometimes glaucous; lamina (main stem) 6–18 × 0.7 mm, linear, apex apiculate to rounded, margin revolute, base cuneate, 1-veined , with laminar glands pale, numerous, marginal glands not visible; leaves (axillary shoots) small, clustered. Inflorescence (1)3–c. 22-flowered, subcorymbiform to broadly pyramidal, 10–20 mm long, with lateral cymules 1–2-flowered, monochasial, without flowering branches below; bracts and bracteoles linear-lanceolate to linear, entire or proximally black-glandular-denticulate. Flowers 10–12 mm in diam., with petals spreading; buds cylindric, rounded. Sepals equal, 1/2–2/ 3 united, not imbricate, 1.5–2 × 0.5–0.7 mm, oblong-elliptic to lanceolate, rounded to acute; veins 3, slightly prominent; margin with regular or irregular, sessile to subsessile, ellipsoid to globose black glands; laminar glands pale, in 2 lines. Petals bright yellow, not red-tinged, 5–7 × 2 mm, c. 3 × sepals, oblanceolate, subunguiculate, rounded to apiculate-obtuse, entire, with few lateral sessile black glands or eglandular; laminar glands pale, punctiform to linear. Stamens c. 25, longest 5–6 mm; filaments not red-tinged. Ovary. 1– 1.5 × 0.5 mm, narrowly ellipsoid, not rostrate; styles 1.5–2 mm, 1.3–1.5 × ovary. Capsule 4–5 × 3 mm, narrowly ovoid-ellipsoid, not rostrate; vittae narrow. Seeds not seen.
