Synonyms: Spergularia marginata Kittel Spergularia maritima (Linnaeus) Chiovenda
Treatment appears in FNA Volume 5. Treatment on page 21.

Plants annual or short-lived perennial with branching caudex, stout, 7–30 cm, glabrous or sparsely stipitate-glandular distally. Taproots slender to moderately stout. Stems erect to ascending or prostrate, much-branched proximally; main-stem 1–4 mm diam. proximally. Leaves: stipules inconspicuous, dull white, broadly triangular, 2.6–6 mm, apex acuminate to spine-tipped; blade linear to broadly so, 0.5–3.5 cm, distinctly fleshy, apex apiculate to spine-tipped; axillary leaf clusters mostly absent, sometimes of 2–4 leaves. Cymes simple or 3+-compound. Pedicels reflexed and oriented to 1 side in fruit. Flowers: sepals connate 0.3–1 mm proximally, lobes often 3-veined, lanceolate to ovate, 2.5–5 mm, to 7 mm in fruit, margins 0.1–0.5 mm wide, apex obtuse to rounded; petals white to apically pink, elliptic to obovate, 0.8–1 times as long as sepals; stamens 9–10; styles 0.5–1 mm. Capsules tan, (4.5–) 5.5–7 (–8) mm, 1.2–1.4 times as long as sepals. Seeds dark reddish-brown, submarginal groove absent, broadly ovate, compressed, 0.8–1.1 mm, ± smooth, not papillate; wings usually present, white to reddish-brown, 0.3–0.5 mm wide, margins irregular. 2n = 18, 36? (both Europe).
