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.
Found scattered in the northern part of south Australia. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
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:
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%.
