Jacksonia angulata is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a tufted, spreading to prostrate shrub often with zig-zagged branches, sharply-pointed side branches or phylloclades, leaves reduced to broadly egg-shaped scales, yellow-orange to orange flowers with a red "eye", and woody, densely hairy pods.
Jacksonia angulata is a tufted, spreading to prostrate shrub that typically grows up to high and wide. It has angular to winged branches, the side branches sharply-pointed phylloclades wide. Its leaves are reduced to broadly egg-shaped, light to dark brown scales, long and wide. The flowers are scattered along the branches on a pedicel long, with narrowly egg-shaped bracteoles long and wide near the top of the pedicels. The floral tube is long and the sepals are papery, with lobes long and wide. The standard petal is yellow-orange to orange with a red "eye" and veins, long, the wings yellow-orange to orange with orange-red markings, long, and the keel is deep red, long. The stamens have whitish-green filaments with a pink tip and are long. Flowering occurs from August to December, and the fruit is a woody, densely hairy pod long and wide.[1]
Jacksonia angulata was first formally described in 1864 by George Bentham in his Flora Australiensis from specimens collected by James Drummond.[2] [3] The specific epithet (angulata) means 'angled', referring to the branchlets.[4]
This species of Jacksonia grows in shrubland or woodland in winter-wet areas between Kalbarri and the Darkin Swamp east of Perth, in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.
This species is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
