Daviesia uncinata is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a densely-branched shrub with many stems, hooked, needle-shaped, sharply pointed phyllodes continuous with the branchlets and rich yellow and pinkish-red flowers.
Description
Daviesia uncinata is a densely-branched shrub that typically grows to a height of up to 70 cm (28 in) and has many stems. Its phyllodes are scattered, circular in cross-section and continuous with the branchlets, 5–70 mm (0.20–2.76 in) long, 1–2 mm (0.039–0.079 in) wide and sharply pointed with a hooked end. The flowers are arranged in a single group of one to several in the axils on a peduncle 1–4 mm (0.039–0.157 in) long, each flower on a pedicel 1.0–1.5 mm (0.039–0.059 in) long. The sepals are 2.5–3.5 mm (0.098–0.138 in) long and joined bell-shaped at the base, the upper two lobes joined for most of their length and the lower three triangular. The standard petal is broadly egg-shaped with a notched centre, about 6–7 mm (0.24–0.28 in) long, 4–5 mm (0.16–0.20 in) wide and rich yellow yellow dark pinkish-red markings. The wings are 5.5–6.0 mm (0.22–0.24 in) long and pinkish-red, the keel 5.5–6.5 mm (0.22–0.26 in) long and pinkish-red with a black tip. Flowering occurs from October to January and the fruit is a flattened, shallowly triangular pod 11–15 mm (0.43–0.59 in) long.[2][3]
Taxonomy
Daviesia uncinata was first formally described in 1995 by Michael Crisp in Australian Systematic Botany from specimens collected by Crisp near Yoting in 1979.[2][4] The specific epithet (uncinata) means "hooked" or "barbed" referring to phyllodes.[5]
Distribution and habitat
This daviesia grows in kwongan in the area between Kellerberrin, Piesseville and Lake Magenta in the Avon Wheatbelt and Mallee bioregions of south-western Western Australia.[2][3]
Conservation status
Daviesia uncinata is classified as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[3] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[6]
