Plant description

Shrub to 2 m high with slender glabrous slightly sulcate (groove0 branches, faintly striated to smooth. Phyllodes divaricate, linear-terete, to 30 mm long and 1.7 ; 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. Fruits are brown, flat, broad-triangular pod to 12 mm long and 10 mm wide, with one seed inside. Seeds are brown with black mottled reniform seed to 6 mm long and 4 mm wide, and a cream aril. Seed embryo type is bent.

Seed collection and propagation

Collect seeds between December and January. Collect maturing brown seed pods from the plant using secateurs or by hand. Plant is prickly so it is advisable to wear gloves. 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. From one collection, the seed viability was high, at 95%. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
