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.
Distribution:
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
Status:
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.
Fruit type:
Brown compressed, obtriangular pod to 13 mm long and 7 mm wide, enclosed at the base by an enlarged calyx.
Seed type:
Compressed reniform seed to 2.5 mm wide.
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 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).
