Census of South Australian plants (external link)     [genus Mollugo]
Name derivation:
Mollugo from the Latin name of a plant believed to be Galium mollugo, a European herb with whorled leaves, applied to the present genus because the leaves appear verticillate. Cerviana means deer (or fawn) colored.
Distribution:
Found scattered in the northern part of south Australia. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Uncommon in New South Wales. Common in the other states.
Plant description:
A delicate little herb, resembling a Sagina, to 8 cm high with whorled stems, branches and leaves, the stems and branches capillary. Leaves linear, to 10 mm long. Flowers on long capillary peduncles, perianth-segments to 3 mm long, obtuse, greenish with a membranous margin. Flowers throughout the year.
Fruit type:
Brown ovoid capsule, enclosed in the perianth, opening in 3 valves which has the remains of a septum down their middle.
Seed type:
Very small brown reniform seed to 0.3 mm long and 0.3 mm wide, with reticulated surface.
Embryo type:
Peripheral.
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 high, at 100%.
