Daviesia abnormis is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is an erect, hairy shrub with sharply-pointed, narrow elliptic to narrow egg-shaped phyllodes with the narrower end towards the base, and yellow flowers with faint red markings.

Description

Daviesia abnormis is an erect shrub that typically grows to a height of 30–70 cm (12–28 in) and has densely hairy foliage. The phyllodes are crowded near the ends of branchlets and are sharply pointed, narrow elliptic to narrow egg-shaped with the narrower end towards the base, 13–23 mm (0.51–0.91 in) long and 3–8 mm (0.12–0.31 in) wide. The flowers are arranged singly on a pedicel 1–3 mm (0.039–0.118 in) long with bracts about 1 mm (0.039 in) long, the flowers almost obscured by the phyllodes. The five sepals are 4–5 mm (0.16–0.20 in) long and joined at the base, the two upper lobes more or less fused and the lower three triangular. The petals are yellow with faint red markings, the standard petal 11–13 mm (0.43–0.51 in) long, the wings 9–11 mm (0.35–0.43 in) long and the keel sac-like and 10–11 mm (0.39–0.43 in) long. Flowering occurs in March and April and the fruit is a flattened pod 11–13 mm (0.43–0.51 in) long.[2][3]

Taxonomy and naming
