Name derivation:
Daviesia named after the Rev. Hugh Davies (1739-1821), a Welsh botanist and an Anglican clergyman. Stricta from the Latin 'strictus' meaning very upright or very straight, referring to the branchlets and phyllodes, which are usually stiffly erect.
Endemic to South Australia and found only in the northern Flinders Ranges growing on ridge-tops and precipitous mountain slopes on skeletal, quartzite-derived soils in mallee-shrubland
Native. Rare in South Australia.
Plant description:
Open shrub to 1.5 m tall with rigidly erect branchlets that are compressed, narrowly winged, and smooth. Phyllodes arranged spirally, erect or ascending, flat, narrow to linear-elliptic, obtuse or acute, articulate at base, to 100 mm long and 15 mm with with prominent midrib. Inflorescence in umbels of 1-5 per axil with orange  purplish-centred pea-flowers, fading to yellow-brown. Flowering between August and October.

Seed type:
Compressed reniform seed to 2.5 mm wide.
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 wiht 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).
