Plant description

Erect bushy shrub to 2 m high with glabrous, dull green to yellowish stems. Phyllodes occuring only near the apex of new season stems and reduced to scales at the lower nodes, pungent-tipped, to 25 mm long and 1.75 mm diameter, rigid, smooth or with faintly ribbed. Inflorescence 1 spike per axil with 4 to many orange to red pea-flowers. Flowering between August and October. Fruits are broad obovate to obtriangular pod to 7 mm long and 6 mm wide, strongly compressed, red to pale brown at maturity. Seeds are orange to brown with black mottle, reniform seed to 3.5 mm long and 2 mm wide. Seed embryo type is bent.

Seed collection and propagation

Collect seeds between October and December. 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 with 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 100%. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
