Flowers: petals white or purple-tinged, (3–)4–5.6 × (1.3–)2–3.3(–3.8) mm. Fruits usually fertile and fully developed, not or weakly torulose, (1–)1.2–1.8(–2) mm wide; septum often fenestrate (with circular perforations at regular intervals longitudinally or with a narrow, elliptical, longitudinal split at base or both). 2n = 42.
Phenology: Flowering Jun–Jul, fruiting Jul–Aug.
Habitat: Sand, clay, and gravel slopes and plains
