DIAGNOSTIC DESCRIPTION
Perennial herb 0.05-0.35 m tall or long, decumbent from creeping and rooting base, with stems solitary? or clustered, often branched below inflorescence or lower, with branches slender, spreading. Stems terete or 2-4(6)-lined, eglandular or occasionally with few reddish glands on lines; internodes 8-50 mm, longer than leaves. Leaves sessile or to 2 mm petiolate; lamina 4-24 ´ 2-17 mm, ovoid to oblong or elliptic to obovate or oblanceolate, paler or usually glaucous beneath, plane, subchartaceous; apex rounded, margin entire, base cordate to rounded or cuneate, the upper often with black-glandular-ciliate auricles and sometimes also glandular-ciliate proximal margin; venation: 2-4 pairs of main laterals from lower quarter to almost half of midrib, with tertiary reticulation dense; laminar glands pale, punctiform, small to medium, dense; intramarginal glands black, dense. Inflorescence 1-12-flowered, from 1(2) nodes, often with flowering branches from up to 4 nodes below, the whole subcorymbiform; pedicels 1.5-4 mm; bracts and bracteoles narrowly elliptic or linear-lanceolate to linear, black-glandular-ciliate and -auriculate or more rarely entire and then either bracteose or reduced-foliar, persistent. Flowers 10-20 mm in diam., stellate; buds ovoid to broadly ellipsoid, obtuse to acute. Sepals 5, 3.5-7 ´ 1-2.5 mm, equal to subequal, erect in bud and fruit, ovate-lanceolate or elliptic to linear-lanceolate, subacute to acute or rarely rounded, glandular-ciliate to entire; laminar glands pale or often partly black, linear (with black parts dots to usually streaks) to dots; marginal glands black, on cilia or sessile or absent. Petals 5, bright yellow, sometimes tinged red in bud, 6-10 ´ 2-4 mm, 1.2-2 ´ sepals, oblong-elliptic to oblanceolate, rounded, margin entire or rarely with one apical glandular cilium, laminar glands black, striiform, or absent, marginal glands absent or 1-4, black, apical and subapical, sessile or apical on cilium. Stamens 12-30, '3'-fascicled, longest 4-7 mm, 0.65-0.85 ´ petals; anther gland black. Ovary 3-locular, 2-3.5 ´ 1.5-2 mm, ovoid to ellipsoid; styles 3(4), 2-3 mm, 0.65-1(-1.3?) ´ ovary; stigmas narrowly capitate to narrow. Capsule 3-9 ´ 2.5-6 mm, ± broadly ellipsoid, exceeding or equalling sepals. Seeds yellowish-brown, 0.5-0.6 mm, cylindric; testa densely scalariform-foveolate.
