Leaves alternate, with leaf-blade to 35 mm long and 60 mm wide, covered in soft hairs, sometimes hairless, ternately dissected, segments linear-oblong to elliptic, entire, petiole to 30 mm long. Inflorescence singular or in clusters of 3–6 yellow-green or white-cream flowers, with hairy bracts. Flowering between June and January.

Seed collecting:
Collect maturing fruits by picking off clusters that are turning pale brown with a hard seed inside.
Seed cleaning:
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.
