Spergularia bocconei
(Scheele) Graebn.Annual or biennial; taproot slender; stems slender, prostrate to erect, 5–20(–30) cm long, glabrous only below. Leaves linear, mucronate or shortly awned, not fasciculate, fleshy, 10–30(–45) mm long, 0.4–1 mm wide; upper leaves more or less glandular-hairy; stipules not acuminate, 1.5–4 mm long, connate for less than half their length, dull-white, not silvery. Inflorescence often dense, with branches monochasial and racemose; pedicels not reflexed, filiform, mostly shorter than or equalling sepals and capsules, densely glandular-hairy. Flowers 6–10 mm diam.; sepals (2–)2.5–3.5(–5) mm long, green or purplish, the dense glandular hairs (0.15–)0.3–0.4(–0.5) mm long; petals usually shorter than sepals, white, or rose-pink inside; stamens (0–)2–5(–10). Capsules ovoid to subglobose, equalling or slightly longer than sepals; seeds 0.35–0.6 mm long, smooth to finely papillose, light grey-brown, unwinged. Flowers mostly Sep.–Dec.
