Perennial herb, 0.15–0.65 m tall, glabrous, erect, not rooting from base, sometimes with short branches below inflorescence, with sterile shoots prostrate to ascending. Stems not glaucous, with scattered amber or reddish gland dots especially towards base, not or slightly prominent; internodes 12–40 mm, exceeding leaves. Leaves shortly (to 1.5 mm) petiolate, not glaucous; lamina (main stem) 8–28 × 1–6 mm, linear to narrowly elliptic, apex rounded, margin plane or ± revolute, base cuneate, with up to 3 pairs of lateral branches from lower half, with laminar glands pale, small, scattered, marginal glands pale; lamina (axillary and sterile shoots) smaller, narrower, otherwise similar. Inflorescence c. 13–∞-flowered, from 8–10 nodes, narrowly cylindric to narrowly pyramidal, rather dense, 80–220 mm long, with lateral cymules 1–3(–5)-flowered, bracts and bracteoles lanceolate. Flowers 12–21 mm in diam., with petals reflexed after flowering; buds ovoid-cylindric. Sepals subequal to equal, ⅓–½ united, not imbricate, 1.5–2 × 0.5–1 mm, elliptic-oblong to oblong, rounded; veins 3; margin distally with few regular sessile globose black glands; laminar glands pale, linear to striiform. Petals rather pale yellow, sometimes red-veined, 8–12 × 4.5–6 mm, 5–6 × sepals, oblanceolate, unguiculate, rounded, distally shortly black-glandular-ciliate; laminar glands pale, ± numerous, punctiform to shortly striiform. Stamens 30–40, longest c. 6–7 mm; filaments sometimes red-tinged. Ovary c. 2 × 1 mm, ovoid, not rostrate; styles c. 4 mm, c. 2 × ovary. Capsule 4–7 × 3–4.5 mm, broadly ovoid to globose. Seeds dark brown, 1.5–1.7 mm long.
