Plant description

Small, erect annual herb to 50 cm high, often with many stems. Leaves to 50 cm long, usually divided 1–3 times; upper leaves much smaller than lower; leaflets 3–5, ovate-cuneate, to 2.5 cm long, often deeply 3-lobed with lobes again divided. Inflorescence in clusters to 4 cm diameter with tiny white flowers and a reddish mid rib. Flowering between September to December. Fruits are brown ovoid cluster to 1.5 mm long, with a number of seed segments. Seeds are pale-brown wedge-shaped seed to 1 mm long and 0.5 mm wide, with 5 slender ribs. Seed embryo type is linear under-developed.

Seed collection and propagation

Collect seeds between November and February. Collect maturing fruits by picking off the clusters that are turning brown. Place the fruits in a tray and leave to dry for one to two weeks. Then rub the fruits with a rubber bung 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.
