Name derivation:
Daviesia named after Rev.

Distribution:
Endemic to South Australia and found mainly in the southern Mount Lofty Ranges, growing on sandy to rich loam soils high in phosphorous in undulating hilly to mountainous country.
Status:
Native. Common in South Australia.
Plant description:
Divaricate shrub to 1.8 m high. Leaves narrow-elliptic to -ovate or linear, to 22 mm long and 3 mm wide, upper face convex with mid-rib more prominent than below. Inflorescences 1 or 2 per axil with rosy red to deep orange-red pea-flowers.

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 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:
From two collections, the seed viability was average, at 65%.
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).
