Perennial woody herb 0.2-0.45 m tall, fasciculate, with branches 1-many from underground rootstock, erect, much branched. Stems 4-lined and ancipitous when young, soon terete, eglandular. Leaves sessile or rarely to 0.5 mm petiolate; lamina 9-20 x 5-12 mm, broadly elliptic to obovate, paler but not glaucous beneath, plane, spreading; apex obtuse to rounded, base cuneate to rounded; venation: 1-3 pairs of main lateral veins, much branched to form fairly conspicuous tertiary reticulation;laminar glands pale, punctiform; intramarginal glands spaced, black. Inflorescence 1 -flowered, with (usually) paired flowering branches from 1-2 or more (up to 10) nodes below; pedicels 4-10 mm in fruit. Flowers c. 10-14 mm in diam., stellate; buds ellipsoid, obtuse. Sepals 4-8 x 1.5-4 mm, imbricate, unequal, elliptic to obovate or spathulate, rounded-subapiculate to rounded, entire; veins 5, branched and reticulating; laminar glands pale, dense, shortly striiform to punctiform; infra marginal glands few, mostly subapical, black. Petals yellow, not tinged red, 6.4-7 x 1.7-2.5 mm, c. 0.9-1.5 x sepals, elliptic to oblong or spathulate, rounded, apiculus subterminal, obscure to obsolete; laminar glands few, pale or absent; marginal glands absent or few, black, near apex. Stamens irregularly 3-fascicled or not fascicled, c. 30, longest 3-5 mm, c. 0.5-0.7 x petals; anther gland black. Ovary 2.5-3 x 2 mm, ovoid-cylindric, obtuse; styles 3-4(5), 2-2.5 mm long, 0.8-0.9 x ovary; stigmas narrowly capitate; placentae axile.
