Census of South Australian plants (external link)     [genus Daviesia]
Name derivation:
Daviesia named after Rev. Hugh Davies (1739-1821), a Welsh botanist and an Anglican clergyman. Arenaria from the Latin 'arena' meaning sand; referring to the species sandy habitat.
Distribution:
Found in the southern part of South Australia, growing in mallee scrublands and open-forests usually on deep sand or skeletal soils. Also found in New South Wales and Victoria.
Status:
Native. Common in South Australia. Uncommon in New South Wales. Common in Victoria.
Plant description:
Low-spreading shrub to 1.5 m high, branchlets numerous, divaricate, rigid and spiny, rather 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. Flowers 1 rarely 2 per axil, orange-pink, maroon and yellow pea-flowers. Flowering between September and October.
Fruit type:
Pale brown asymmetrically triangular pod to 7 mm long and 4 mm wide, beaked with the persistent style, with one seed inside.
Seed type:
Orange-brown with black mottled reniform seed to 4 mm long and 2 mm wide, and a cream aril.
Embryo type:
Bent.
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 high, at 100%.
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).
