DIAGNOSTIC DESCRIPTION
Perennial herb 0.13–1.05 m tall, erect, not creeping and rarely rooting at base, branching above or at most nodes with branches ascending. Stems terete, often turning vinous red, uniformly black-gland-dotted or shortly -streaked; internodes 10–50 mm, slightly exceeding to shorter than leaves. Leaves sessile or rarely up to 1 mm petiolate; lamina 14–40(–58) × 3–17(–22.5) mm, triangular-lanceolate or lanceolate or oblong to elliptic or oblanceolate, paler beneath, chartaceous; apex rounded to retuse or rarely obtuse to acute, margin plane, base cordate to narrowly cuneate; venation: (3)4(5) main laterals from base to lower half of midrib, tertiary reticulation dense, rather obscure, visible beneath; laminar glands mostly pale to all black, punctiform, small, dense; intramarginal glands black, dense. Inflorescence 10–60-flowered, from 3 nodes, dense to rather lax but with partial inflorescences dense, sometimes with subsidiary branches from up to 12 nodes below, the whole subcorymbiform to cylindric and up to 200 (more rarely to 600)-flowered; pedicels 1–2.5 mm; upper leaves reduced to bracteose; bracteoles 1–4.5 mm long, linear-subulate, entire. Flowers 8–15 mm in diam., stellate; buds ovoid, subacute, not red-tinged. Sepals 5, subequal, free, (1.5–)2–4 × 0.8–1.6 mm, lanceolate or oblong-lanceolate to elliptic or ovate-elliptic, acute to rounded, entire and eglandular or rarely with few sessile glands; veins 5–3; laminar glands all pale to all black, linear to punctiform, dense; marginal glands absent or few, black, sessile. Petals 5, pale yellow, not red-tinged, 3–6(–9) × (1.5–)1.9–2.5(–3.5) mm, 1.5 × sepals, oblanceolate to elliptic, obtuse, entire; laminar glands all or mostly black, linear to usually punctiform; marginal glands black, distal, sessile. Stamens (20–)30–60, ‘3’-fascicled, longest (3–)4.3–6(–9) mm, equalling petals; anther gland black. Ovary 1.3–4 × (1.3?–)1.5–2.5(–3.5?), broadly ovoid; styles 3, 1–4 mm, 1–1.3 × ovary; stigmas narrowly capitate. Capsule 2.5–4.4(–6) × 2–3.5(–4) mm, ovoid to subglobose, longitudinally vittate or with scattered elongate to ovoid vesicles (sometimes black). Seeds dark brown, 0.5–0.7 mm long; testa densely linear-reticulate.
