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.
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.
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:
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).
