Spergula arvensis

Plants glabrous or, often, glandular. Stems usually branched proximally, 10–50+ cm. Leaf blades usually appearing terete, 1.5–3(–5) cm, margins often revolute, forming abaxial channel. Pedicels erect to ascending, reflexed, secund in fruit. Flowers: sepals 3.5–5 mm; petals ovate, 3/4–1 times as long as sepals in flower, apex obtuse; stamens usually 10. Capsule valves 3.5–5 mm. Seeds sometimes keeled or winged, subglobose, 1–1.1 mm wide, surface minutely roughened or obscurely low-tuberculate (50×), covered with white, club-shaped papillae in part or throughout (packing of seeds in capsule may prevent papillae development in spots), wings white, ± 0.1 mm wide. 2n = 18, 36 (both Europe).
