Census of South Australian plants (external link)     [genus Spergularia]
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. Marina means of the sea.
Distribution:
Found across much of South Australia, growing primarily in and around edges of salt marshes and other saline environments. Also found in all states.
Status:
Native. Common in South Australia. Uncommon in Northern Territory and Queensland. Common in the other states.
Plant description:
Annual, biennial or perennial herb to 35 cm high. Leaves linear-lanceolate, acute or mucronulate, to 4 cm long and 1 mm wide, distinctly fleshy. Inflorescence a loose spike with pink or whitish flowers. Flowers throughout the year.
Fruit type:
Brown ovoid capsule to 6 mm long.
Seed type:
Brown reniform seeds to 0.7 mm long and 0.6 mm wide, covered with tubercules.
Embryo type:
Peripheral.
Seed collecting:
Collect capsules that are maturing, fat and turning brown and contain hard brown seeds.
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 one collection, the seed viability was high, at 100%.
