Plant description

Decumbent to sprawling monoecious herb to 60 cm high. Leaves thin, narrowly to broadly rhomboid to 30 mm long, coarsely serrate; upper surface glabrescent, lower surface somewhat scurfy. Male flowers in clusters, female flowers in axillary clusters. Flowering throughout the year. Fruits are brown rhomboid fruit to 5 mm long, flat, joined in the lower half; thin or somewhat thickened with age, scurfy-pubescent; margin entire in the lower half, 2–4-toothed in the upper half. Seed embryo type is peripheral.

Seed collection and propagation

Collect seeds between January and December. Collect fruits that are starting to dry or and turn brown. Fruits can be collected directly from the bush or from the ground underneath. Place the fruits in a tray and leave to dry for one to two weeks. No cleaning is required if only the fruits are collected. The seed can be stored in the fruit or can be cleaned further. Rub the fruit gently by hand to dislodge the seeds. Use a sieve 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.
