Name derivation:
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. Tasmanica of or from Tasmania (Australia); referring to the location where the type specimen was collected from.
Found in the southern part of South Australia,  growing in coastal and inland sandy swamps and salt marshes. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Native. Common in South Australia. Common in the other states.
Plant description:
Perennial herb with thick, woody rootstock and erect to more or less decumbent branches. Leaves flattened, mucronate to shortly caudate. to 80 mm long and 2 mm wide, glabrous to sparsely hairy. Inflorescence a loose spike covered in dense hairs with pink flowers. Flowering between August and December.

Seed cleaning:
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.
Seed viability:
From two collections, the seed viability were average to high, ranging from 75% to 80%.
