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. Diandroides means resembling the species Spergularia diandra.
Distribution:
Found scattered in the eastern side of South Australia, north of Port August, growing on damp sandy soils and salt pans, sometime associated with lignum swamps. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Rare in Western Australia. Uncommon in the Northern Territory and Queensland. Common in New South Wales.
Plant description:
Annual herb with slender taproot, decumbent branches arising from the base. Leaves obtuse often with a mucro, to 20 mm long and 1 mm wide, sparsely glandular-hairy. Inflorescence short spike covered in dense glandular hairs with many white (rarely pink or greenish) flowers on a stalk longer than the sepals. This species is very similar to Spergularia diandra which differ by its usually glabrous leaves with a caudate apex, slightly smaller inflorescence bracts, sepals, petals and capsules and smooth to slightly papillose seeds.
Fruit type:
Brown ovoid to sub-globular capsule to 3.5 mm long hanging down on a short stalk.
Seed type:
Black narrow oblique-pyriform to trigonous seed covered in very densely blunt-papillose hairs, wingless
Embryo type:
Peripheral.
Seed collecting:
Collect capsules that are maturing, fat and turning brown and contain hard dark 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.
