| Daviesia articulata | |
Daviesia articulata is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a rigid, low-lying or erect shrub with scattered, tapering, cylindrical and sharply pointed phyllodes, and yellow and red flowers.
Daviesia articulata is a rigid, low-lying or erect shrub that typically grows up to 1 m (3 ft 3 in) and 2 m (6 ft 7 in) wide. Its leaves are reduced to scattered, tapering cylindrical, sharply-pointed phyllodes, 3–40 mm (0.12–1.57 in) long and about 1 mm (0.039 in) wide. The flowers are arranged in groups of up to five in leaf axils on a peduncle about 1 mm (0.039 in) long, each flower on a pedicel 0.5–3 mm (0.020–0.118 in) long with oblong or spatula-shaped bracts at the base. The sepals are 2.5–4.0 mm (0.098–0.157 in) long, the two upper joined in a broad "lip" and the lower three smaller and triangular. The standard petal is curved backwards, yellow with a red base and bright yellow centre and about 7 mm (0.28 in) long, the wings red with yellow tips and about 6.5 mm (0.26 in) long and the keel dark red and about 5 mm (0.20 in) long. Flowering occurs from August to December and the fruit is a flattened triangular pod 8–11 mm (0.31–0.43 in) long.[2][3]
Taxonomy and naming
Daviesia articulata was first formally described in 1995 by Michael Crisp in Australian Systematic Botany from specimens collected east of Ravensthorpe in 1979.[3][4] The specific epithet (articulata) means "jointed", referring to the base of the phyllode.[5]
