DIAGNOSTIC DESCRIPTION
Perennial herb 0.3-1 m tall, erect, branched from the base and usually with flowering branches from median and upper stem nodes. Stems green, 4-lined, densely gland-dotted, aerenchymatous at the base; internodes 8-20 mm long, about equalling leaves. Leaves sessile, ascending, deflexed when fading, lamina 10-30 x 3-5(-8) mm, narrowly oblong-elliptic (lower) or lanceolate to linear-lanceolate, margin plane, concolorous, not glaucous, subcoriaceous?; apex acute, base cuneate to rounded-subamplexicaul, sometimes subdecurrent; basal or near-basal veins l-3(-5), midrib unbranched or with 1(2) pairs of branches, tertiary reticulation not visible; laminar glands dense, not prominent. Inflorescence up to c. 30-flowered, monochasial after c. 4th grade, with branches from up to 16 lower nodes, the whole broadly pyramidal to subcorymbiform; pedicels 1.5-2 mm long; bracts 2-6 mm long, lanceolate to subulate. Flowers c. 4-10 mm in diam., stellate. Sepals 3-5 x 0.8-1 mm, often unequal, lanceolate, acute to acuminate; veins 3-5, unbranched, all or only midrib prominent; glands linear, distally punctiform. Petals orange-yellow, 6-10 x 5-7 mm, c. 2 x sepals, obovate; apiculus obtuse; glands linear, interrupted distally. Stamens 50-80, irregularly (?) grouped, longest 3-6 mm long, c. 0.5 x petals. Ovary c. 1-1.5 x 0.7-1 mm, ovoid; styles 3, 2-4 mm long, 2-3 x ovary, divergent-incurved; stigmas capitate. Capsule 3-4.5 x 2-2.5(-3 ?) mm, ellipsoid to rostrate-subglobose, shorter than or equalling sepals. Seeds 0.5-0.6(0.65) mm long, testa obscurely linear-reticulate to irregularly reticulate.
