DIAGNOSTIC DESCRIPTION
Perennial herb 0.18-0.45(0.55) m tall, erect or occasionally shortly ascending and rooting from rootstock, with stems solitary or few, usually branched at most nodes. Stems incompletely 2-lined (nodes terete near base), with ± dense black punctiform glands on or near lines and occasionally elsewhere; internodes 8-40 mm, shorter than to usually exceeding leaves. Leaves sessile; lamina 15-25(-33) ´ 3-9(-12) mm, oblong-lanceolate or ovate-lanceolate to triangular-lanceolate, paler beneath, chartaceous; apex subobtuse, margin entire, revolute, base subcordate, subamplexicaul; venation: 3 pairs of main laterals from near base of midrib, tertiary reticulation obscure; laminar glands all pale, dense, or with a few black, scattered, punctiform; intramarginal glands black, rather dense. Inflorescence (1-)5-c. 65-flowered, from 1-4 nodes, with flowering branches from up to 5 nodes below, the whole corymbiform to ± narrowly pyramidal or narrowly cylindric; pedicels 1-2 mm; bracts and bracteoles 3.5-5 mm long, lanceolate, sparsely black-glandular-denticulate. Flowers (15-)20-25 mm in diam., stellate; buds narrowly ovoid, (sub)acute. Sepals 5, free, 4-6 ´ 1-2 mm, erect in bud and fruit, lanceolate to ovate-lanceolate, acute, with ± irregular prominent glands to long-glandular-ciliate; veins 3(5), unbranched; laminar glands pale, linear to distally punctiform; marginal glands black, ± elongate, sessile or on cilia. Petals golden? yellow, not tinged red in bud, (8-)10-12 ´ (3-)5-6 mm, 2.4-4 ´ sepals, oblong-obovate, asymmetric, entire to subentire, laminar glands pale, ± punctiform, distal, marginal glands black, immersed or rarely ± prominent, distally dense. Stamens 40-50, '3'-fascicled, longest 7-10 mm, 0.8-0.9 ´ petals; anther gland black. Ovary 3-locular, 2-2.5(-3) ´ 1-1.5 mm, cylindric-ovoid; styles 3, free, 4-6 mm, 1.7-3 ´ ovary, widely spreading; stigmas narrowly capitate. Capsule (6)-7-8 ´ 4-5 mm, c. 1.5-2 ´ sepals, cylindric-ovoid to conic; valves rather densely longitudinally and obliquely vittate. Seeds yellowish-brown, 0.8-1mm, cylindric, not carinate; testa finely linear-foveolate.
