Name derivation:
Daviesia named after the Rev. Hugh Davies (1739-1821), a Welsh botanist and an Anglican clergyman. Leptophylla from the Greek 'leptos' meaning narrow and 'phyllon' meaning a leaf, referring to the species' long narrow leaves.
  , along a line running from the Flinders Ranges to Kangaroo island, with a few records from the lower South-east. Also found in New South Wales and Victoria.
Native. Common in South Australia. Common in the other States.
Plant description:
Multi-stemmed shrub to 2 m tall with ascending, glabrous and angular branches. Leaves linear-elliptic to linear-obovate, to 90 mm long and to 10 mm wide;, dull yellow-green. Inflorescences in axillary clusters with orange-yellow pea-flowers. Flowering between September and November.
Fruit type:
Brown asymmetrically triangular pod to 2.5 mm long and 1.7 wide; beaked with the persistent style.
Seed type:
Orange-brown with black mottled reniform seed to 6 mm long and 4 mm wide, with a cream aril.
Embryo type:
Seed collecting:
Collect maturing pods that are turning brown with hard seeds inside.
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 one collection, the seed viability was high, at 95%.
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)
