Plants strongly perennial with branched, woody base, stout, 11–30 cm, stipitate-glandular in inflorescence or throughout. Taproots becoming stout, woody. Stems erect to ascending, often arcuately so, much-branched proximally; main-stem 0.4–1.3 mm diam. proximally. Leaves: stipules ± conspicuous, dull white, broadly lance-acuminate, 3–8 mm, apex mucronate; blade filiform to linear, 1–4.2 cm, somewhat fleshy, apex apiculate or spine-tipped; axillary leaves 2–4 per cluster. Cymes simple to 3-compound. Pedicels spreading to reflexed in fruit. Flowers: sepals connate 0.5–0.7 mm proximally, lobes 1-veined or 3-veined, lanceovate to lanceolate, 2.5–4 mm, to 5 mm in fruit, margins 0.1–0.6 mm wide, apex acute to acuminate but often briefly rounded at tip; petals white, ± elliptic, 0.7–0.8 times as long as sepal; stamens 7–10; styles 0.4–0.6 mm. Capsules greenish to tan, (4–) 5–6.5 mm, 1.1–1.3 times as long as sepals. Seeds reddish-brown to dark-brown, often with submarginal groove, broadly ovate, plump, 0.4–0.5 mm, smooth, often sculptured with parallel, wavy lines, papillae often present; wing often present, white, 0.1–0.2 mm wide, margins irregular.
