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. Fruits are brown ovoid capsule, enclosed in the perianth, opening in 3 valves which has the remains of a septum down their middle. Seeds are very small brown reniform seed to 0.3 mm long and 0.3 mm wide, with reticulated surface. Seed embryo type is peripheral.
Seed collection and propagation
Collect seeds between January and December. Collect capsules that are maturing, turning brown and contain hard, brown seeds inside. 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. From one collection, the seed viability was high, at 100%.
