Plant description:
Shrub to 2 m high, with slender glabrous slightly sulcate branches, faintly striated to smooth. Phyllodes divaricate, linear-terete, to 30 mm long and 1.7 mm wide, subulate, pungent-pointed, smooth, articulate on the branches. Flower-spike in axillary racemes with 2-6 yellow to orange pea-flowers. Flowering between September and October.

Seed collecting:
Collect maturing brown seed pods from the plant using secateurs or by hand. Plant is prickly so it is advisable to wear gloves.
Seed cleaning:
Leave the pods in a paper bag to dry for at least a week. Rub the pods gently wiht a rubber bung to dislodge the seeds. Use a sieve to separate the seeds from unwanted material. Store the dried fruit heads with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed viability:
From one collection, the seed viability was high, at 95%.
Seed germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
