Plant description
Suberect or ascending annual herb to 15 cm high, glabrous and somewhat bluish-green. Leaves alternating along the stems to opposite each other, spathulate to obovate, to 12 mm long and 4 mm wide, tips blunt, usually with a short point, glabrous. Inflorescence in short dense clusters at the tops of the stems with white or pink flowers. Flowering between September to April. Fruits are creamy depressed globular capsule to 2.5 mm diameter with 3 lobed and 6 seeds. Seeds are pale yellow sectoroid seed to 0.6 mm long and 0.4 mm wide, covered in white tuberculate. Seed embryo type is spatulate fully developed.
Seed collection and propagation
Collect seeds between November and June. Collect individual mature capsules, those that are drying off, fat and contain dark hard seeds or pull out the whole plant (annual) to allow capsules to continue to mature. Green capsules can be collected if the seeds are dark and hard. Place the capsules in a tray and leave to dry for one to two weeks. Then gently rub the capsules with a rubber bung to dislodge the seeds. Use a sieves to separate the unwanted material. 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.
