Fruits are grey-brown narrowly pyramidal to suboblong fruit to 2 mm long and 0.5 mm wide just above base on very short stalk with six seed segments (carpels), 3 fertile alternating with 3 undeveloped sterile ones. Seeds are grey-brown wedge-shaped seed 2 mm long and 0.5 mm wide, with 2 minute lateral obtuse points at the base. Seed embryo type is linear.
Seed collection and propagation
Collect seeds between August and November. Collect mature fruits either by breaking off individual spikes or by removing plants that are drying off with fruits that are greyish or brown and seed segments coming apart easily. Place the fruit spikes in a tray and leave to dry for 1 to 2 weeks. Then rub the dried fruit spikes with a rubber bung to dislodge the seeds. Use a sieve to separate any 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. From one collection, the seed viability was high, at 100%.
