Description

Dillwynia uncinata is an erect, spreading shrub that typically grows to a height of about 50 cm (20 in) and has silky-hairy upper stems. The leaves are cylindrical, mostly 3–7 mm (0.12–0.28 in) long, about 0.5 mm (0.020 in) wide on a petiole up to 1 mm (0.039 in) long. The flowers are arranged in more or less sessile groups of two to five, each flower on a pedicel 1–2 mm (0.039–0.079 in) long. The sepals are hairy, 4–5 mm (0.16–0.20 in) long and the standard petal is 8–10 mm (0.31–0.39 in) long and yellow with a red centre. The wings are slightly shorter and the keel shortest and reddish. Flowering occurs from September to November.[2][3][4]

Taxonomy and naming

This species was first formally described in 1853 by Nikolai Turczaninow in Bulletin de la Société impériale des naturalistes de Moscou[5] and was given the name Eutaxia uncinata.[6] In 1916, John McConnell Black changed the name to Dillwynia uncinata in the Transactions and Proceedings of the Royal Society of South Australia.[7][8] The specific epithet (uncinata) means "hooked" or "barbed", referring to the leaves.[9]

Distribution

This dillwynia grows in heath, on dunes and in swampy areas in the south-west of Western Australia, in south-eastern South Australia and in the north-west of Victoria.[2][3][4]

Conservation status

Dillwynia uncinata is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[2]
