Etymology
Spergularia is derived from the genus Spergula, first used by De l'Obel for Sagina spergula which is now known as Spergula amensis, and probably derived from the Latinisation of Spergel, the German name of this plant or from the Latin 'spargo' meaning sow or scatter; referring to the discharge of seeds. Brevifolia from the Latin 'brevis' meaning short and 'folium' meaning leaf.
Distribution and status

Plant description
Annual, biennial or short-lived perennial herb with slender to woody, branching rootstock and erect or occasionally decumbent branching from the base. Leaves in sworls, flattened, usually prominently caudate, sometimes obtuse to mucronate, to 20 sometimes up to 40 mm long, and 2 mm wide, at least the upper surface with hairy, rarely all glabrous. Inflorescence covered in sparse to dense hairs with few white to pink or lilac flowers with 5 petals. Fruits are brown narrow-ovoid to subglobose capsule to 6 mm long. Seeds are dark brown to black reniform seeds to 0.7 mm long and 0.6 mm wide, covered with tubercules only along the outer edge. Seed embryo type is peripheral.
Seed collection and propagation
Collect seeds between October and December. Collect capsules that are maturing, fat and turning brown and contain hard dark seeds. Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules gently by hand or with a rubber bung to dislodge the seeds. Use a sieve to separate the unwanted material. Be very careful as the seeds are very small. Seeds should be hard and brown. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 100%.
