Plant description:
Woody divaricatd shrub to 8 cm high, sometimes wider than high, with branches ending in spines.. Leaves glabrous, dark green, broad lanceolate, to 33 mm long and 5.5 mm wide with a pointy tip. Flowers axillary with orange-red pea-flowers. Flowering between September and October. 
Fruit type:
No pods have been observed on any plants. The plant appears to be suckering.

Seed collecting:
If pods are observed, collect the maturing one that are turning brown and contain dark hard seed 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 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 germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
