Herbs, annual, prostrate, sometimes tinged red, 1–6 dm, forming tangled masses 3–10 dm diam., lightly scurfy when young. Leaves numerous, sessile or proximal short petiolate; blade greenish adaxially, paler abaxially, oblanceolate to spatulate-elliptic or oval, (3–)5–18 × 1–8 mm, margin entire, more scurfy abaxially. Staminate flowers in glomerules largely in distal bractless axils, thus short spicate; calyx 5-cleft. Pistillate flowers in proximal axils. Fruiting bracteoles subsessile or stipe to 0.3 mm, suborbiculate to obovate, 1–1.5(–2) × 1.1–1.8 mm, united to middle, margin minutely 3–5-toothed at apex, otherwise entire, apex green, faces smooth or rarely tuberculate. Seeds light brown, 0.8–1 mm.


Phenology: Flowering early spring–fall.
Habitat: Mainly on sea bluffs
Elevation: 0-100 m
