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.
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.
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:
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 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).
