DIAGNOSTIC DESCRIPTION
Perennial herb 0.09–0.35 m tall, erect or decumbent and sometimes rooting at the base, with stems few to numerous, sometimes with branches from base and/or upper stem nodes. Stems narrowly 2-lined, with amber to reddish scattered glands (not on lines); internodes 4–25 mm, shorter than to longer than leaves. Leaves sessile to subsessile, ascending; lamina 4–20(–24) × 1–6 mm, linear to lanceolate or narrowly elliptic or oblong-elliptic or (lower) oblanceolate, slightly paler beneath, chartaceous; apex obtuse to rounded, margin plane to revolute, base cuneate to rounded; venation: without or with 1–3 pairs of main branches from lower 2/5–1/2 of midrib, reticulate venation obscure or absent; laminar glands pale, punctiform, dense; intramarginal glands black, small, regular to irregular and few or sometimes absent. Inflorescence 3–c. 50-flowered, from 1–3 nodes, sometimes with flowering branches from 1–3 nodes below, the whole broadly pyramidal to cylindric; bracts and bracteoles ovate-lanceolate to linear-lanceolate, margin glandular- or eglandular-setaceous, without auricles. Flowers 12–18 mm in diam.; buds ovoid-ellipsoid, acute. Sepals equal, not or slightly imbricate, basally connate, 4.5–6 ×1.5–3 mm (excluding fimbriae), linear-lanceolate to ovate-lanceolate, acute, irregularly glandular-fimbriate; veins 3, unbranched; laminar glands pale, punctiform to striiform, rarely also 1–2 black, elongate-punctiform; marginal glands black, on and sometimes between fimbriae. Petals bright yellow, 7–12 × 3–4 mm, 1.8–2 × sepals, ± curved oblong-lanceolate, rounded; laminar glands pale and rarely a few black, punctiform; marginal glands black, sessile or on denticles or cilia. Stamens 50–60, ‘3’-fascicled, longest 5–10 mm, c. 0.7–0.8 × petals; anther gland amber. Ovary 1.5 × 1 mm, ovoid; styles 3, c. 4 mm, c. 3 × ovary, diverging. Capsule c. 5–6 × 3–4 mm, about equalling sepals, ovoid, rather sparsely vittate. Seeds not seen; testa reticulate-scalariform (Stefanoff, 1932, t. 4 f. 3).
