SA Census:
Census of South Australian plants (external link)     [genus Glinus]
Name derivation:
Glinus from the Greek 'glinos' meaning a plant with sweet sap. May have been a reference to maple. Lotoides means resembling the genus Lotus, the ancient Greek name for various legumes.
Distribution:
Found in north, north-eastern and eastern South Australia growing on the floodplains of the River Murray and northern rangelands. Also found in all mainland States.
Status:
Native. Common in South Australia. Common in the other States.
Plant description:
Spreading prostrate soft, grey hairy herb to 1 m across. Leaves alternate and/or opposite; elliptic to obovate to 20 mm long, hairy. Flowers in leaf-opposed clusters of 1-8; perianth-segments usually 6-8 mm long, white or yellow inside. Flowering throughout the year.
Fruit type:
Dehiscing dry caspule, enclosed in the perianth with 5-valves.
Seed type:
Shiny red-brown, reniform seed to 0.7 mm long and 0.5 mm wide, with tuberculate surface.
Embryo type:
Peripheral.
Seed collecting:
Collect capsules that are maturing, turning brown and contain hard, brown seeds. 
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 two collections, the seed viability was high, at 100%.
Seed germination:
This species has physiological dormancy and can be difficult to germinate. Germination success of 94% has been achieved by Kew Gardens by pre-treating seeds with 250mg/L gibberellic acid and incubated at constant 20oC (see http://data.kew.org/sid). Germination success of 20% achieved from seeds heated in 120oC oven for 10 min, plated into 50mm glass petri dishes with sponge and filter paper and incubated at 10C/22C, 12/12 dark/light. (23/05/08).
