Low-spreading shrub to 1.5 m high with numerous, divaricate, rigid and spiny branchlets, stiffly pubescent, rarely glabrous. Phyllodes sessile, articulate, broad-ovate and cordate, occasionally narrow- to broad-elliptic and attenuate basally, or rarely obovate, cuspidate, pungent-pointed, rigid, to 10 mm long and 8 mm wide, stiffly pubescent, folded upwards, lower surface with thickened marginal nerves and midrib. Inflorescence 1, rarely 2 per leaf axil with orange-pink, maroon and yellow pea-flowers. Flowering between August and October. Fruits are pale brown asymmetrically triangular pod to 7 mm long and 4 mm wide with one seed inside, beaked with the persistent style. Seeds are orange-brown with black mottled reniform seed to 4 mm long and 2 mm wide, and a cream aril. Seed embryo type is bent.
Seed collection and propagation
Collect seeds between November 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 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. Seed viability is usually high. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
