Name derivation:
Glinus from the Greek 'glinos' meaning a plant with sweet sap; may have been a reference to maple. Orygioides means resembling the genus Orygia.
Found in the north and north-eastern parts of South Australia, growing in seasonally damp places. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Native. Rare in south Australia. Presume extinct in New South Wales. Uncommon in the other states.
Plant description:
Prostrate or spreading perennial herb to 50 cm diameter, the whole plant glabrous except for the youngest parts. Leaves opposite and/or alternate, semisucculent, oblanceolate to obovate, to 15 mm long, obtuse. Flowers in terminal or, less often, leaf-opposed clusters. Perianth segments white or with a pinkish tinge. Stamens 15–20 with a few staminodes, carpels 3 or 4, styles 3 or 4. Flowers possible all year round.
Fruit type:
Brown capsules.
Seed type:
Shiny red-black, reinform seed to 1.2 mm long and 0.7 mm wide, with striated surface. Seeds larger than in the other two species.
Embryo type:
Seed collecting:
Collect capsules that are maturing, turning brown and contain hard, brown seeds inside.
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Be careful as the seeds are very small. 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 average, at 70%.
Seed germination:
This species has physiological dormancy and can be difficult to germinate.
