Plant description:
Prostrate or erect sub-shrub to 30 cm high. Leaves usually crowded, oblong to broadly lanceolate, not spreading to 3 mm long and 1 mm wide, thick, concavo-convex or semi-elliptic, apex obtuse. Flowers solitary in axils, white or pink, to 6 mm across. Flowering between August and November.
Fruit type:
Small brown woody capsule to 3 mm diameter with 2 cells.
Seed collecting:
Collect mature capsules, those that are turning brown, hard with non-open valves. Maturing fruits need to be observed as most will naturally release their seed.
Seed cleaning:
Place the capsules in a tray and leave to dry for a week or two. This allows the valves on the fruit to open and release the seeds. Separate the seeds by placing all the materials into a bucket and shaking it to dislodge the seeds. Pass the material through a sieve to separate the unwanted material. The finer material will contain both seeds and frass usually distinguishable from each other. With finer sieves, the seeds can be separated from the frass but this is not essential for storage or propagation. 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.
