Daviesia microcarpa, commonly known as Norseman pea,[2] is a species of flowering plant in the family Fabaceae and is endemic to two small areas of inland Western Australia. It is a sprawling shrub with tangled stems and crowded, needle-shaped, sharply-pointed phyllodes, and orange and pinkish-red flowers.
Daviesia microcarpa is a sprawling shrub, typically up to 0.4 m (1 ft 4 in) high and 1 m (3 ft 3 in) wide with many weak, tangled stems. Its phyllodes are crowded, needle-shaped and sharply pointed, 8–20 mm (0.31–0.79 in) long and 0.5–0.75 mm (0.020–0.030 in) wide. The flowers are arranged singly or in pairs in leaf axils on a peduncle 0.5–1.5 mm (0.020–0.059 in) long, each flower on a pedicel about 1 mm (0.039 in) long with oblong bracts 0.75–1 mm (0.030–0.039 in) long at the base. The sepals are about 3 mm (0.12 in) long and joined at the base, the lobes more or less similar, triangular and about 0.5 mm (0.020 in) long. The standard petal is egg-shaped, about 4–5 mm (0.16–0.20 in) long and orange with pinkish red markings, the wings 4.0–4.5 mm (0.16–0.18 in) long and pinkish red, and the keel about 3.5–4.0 mm (0.14–0.16 in) long and pale orange-pink. Flowering occurs in August and September and the fruit is a triangular pod 4.0–4.5 mm (0.16–0.18 in) long.[3][4]
Taxonomy and naming
Daviesia microcarpa was first formally described in 1995 by Michael Crisp in Australian Systematic Botany from specimens collected near Norseman in 1979.[5] The specific epithet (microcarpa) means "small-fruited", referring to the phyllodes.[6]
