Fruits are brown ovoid capsule to 5 mm long. Seeds are small diamond-shaped seed to 0.5 mm long and 0.3 mm wide, with deep wrinkles and mesh-like surface. Seed embryo type is spatulate under-developed.
Seed collection and propagation
Collect seeds between September and December. Collect mature capsules as they dry off and turn brown. They should contain hard brown seeds inside. Place the capsules in a tray for a week. Then rub the capsules with your fingers to dislodge all 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 85%.
