Synonyms: Arenaria axillaris Luehm. ex Ewart APNI*
Description: Annual, spreading mat, straggly or shortly erect herb to 20 cm long, with many short, vegetative side shoots, rooting at nodes, glabrous or rarely scabrous.
Stem and inflorescence leaves a continuous series, sessile, lanceolate, narrow-ovate or linear, often falcate, 1.5–17.5 mm long, 0.4–2.3 mm wide, acute.
Inflorescence axillary and solitary or rarely 2 flowers on same stem. Pedicels 2.7–20 mm long, usually deflexed in mature fruit. Sepals elliptic to ovate, 1.3–2.4 mm long, obtuse or acute, apex folded over to form a hood, hood 0.1– 0.45 mm long, sometimes margins minutely serrate or ragged. Petals 2–3.9 mm long, slightly longer to twice sepal length, deeply bifid. Stamens 10, rarely 1 or 2 missing.
Capsule ellipsoid or ovoid, 2.5–3.7 mm long, equal to up to twice as long as sepals. Seeds 4–9, ellipsoid or suborbicular, 0.9–1.2 mm long, red to dark ruby red, tubercles semiinflated ridges.
Distribution and occurrence: The taxon occurs from Rules Point on the Murrumbidgee River, south to Lake Eucumbene, Hume Weir then west along the entire length of the Murray River system. In Victoria it occurs in the east around the Goulburn River and coastal areas near Sale and in the west, it is scattered through the Grampians and Dimboola areas.
