DIAGNOSTIC DESCRIPTION
Perennial herb, 0.27–0.64 m tall, glabrous, erect, not rooting from base, not branching above base, with sterile shoots erect. Stems not glaucous, with rather few scattered amber glandular dots especially near base, not prominent; internodes 12–40 mm, exceeding leaves. Leaves sessile, not glaucous; lamina (main stem) 12–25 × 1–4 mm, linear to narrowly elliptic, apex obtuse to rounded, margin plane to usually revolute, base cuneate to rounded, 1-veined or with up to 3 pairs of lateral branches from lower half, with laminar glands pale and sometimes a few black, marginal glands pale or 1–2 black; lamina (axillary and sterile shoots) smaller, narrow, apex obtuse to rounded. Inflorescence c. 20–∞-flowered, from 12–20 nodes, narrowly cylindric, dense, 140–300 mm long, with lateral cymules 1–3-flowered, without flowering branches; bracts and bracteoles triangular-ovate to triangular-lanceolate, entire. Flowers 12–20 mm in diam., spreading after flowering; buds globose. Sepals unequal to subequal, free or to ⅓ united, ± imbricate or not, 2–3 × 1–2 mm, elliptic (or rarely ovate-elliptic) to oblong or semicircular, subacute to rounded; veins 3(5); margin wholly or distally with regular sessile globose black glands or rarely partly eglandular; laminar glands pale, linear or interrupted. Petals rather pale yellow, not red-tinged, 8–10 × 4–6 mm, 3.5–4 × sepals, obovate-oblanceolate, unguiculate, rounded, distally shortly black-glandular-ciliate; laminar glands pale, few, punctiform to shortly striiform. Stamens 30–45, longest c. 7–8 mm; filaments not red-tinged. Ovary 3 × 1.5 mm, ovoid, shortly acuminate; styles 3.5–4 mm, 1.2–1.3 × ovary. Capsule c. 10 × 4 mm, ovoid-acuminate to ovoid; vittae narrow. Seeds dark brown, c. 2 mm long.
