Spreading to erect annual shrub to 1 m high, with quadrangular branches. Lower leaves lanceolate with a cuneate base and margin entire to deeply serrate, often hastate with forwardly directed lobes to 10mm long. Flowers along a long spike, first continuous and later in disjunct clusters. Flowering between January and April. Fruits are fruit deltoid, acute to 4 mm long and wide, united in the lower half or free to the base, entire or with 1 or 2 teeth; smooth or with a warty surface, becoming black and thickened with age. Seeds are dark brown, circular convex seed to 2 mm long and wide. Seed embryo type is peripheral.
Seed collection and propagation
Collect seeds between May and July. 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. From one collection, the seed viability was high, at 100%.
