Description

Daviesia pachyphylla is usually a slender shrub that typically grows to a height of up to 1.5 m (4 ft 11 in) and often has arching branchlets. Its phyllodes are crowded with overlapping bases, 12–27 mm (0.47–1.06 in) long and 4–10 mm (0.16–0.39 in) wide with a sharply pointed tip. The flowers are arranged in groups of two to seven in leaf axils on a thick peduncle 0.5–5 mm (0.020–0.197 in) long, the rachis 1.25–6.0 mm (0.049–0.236 in) long with bracts 0.5–2 mm (0.020–0.079 in) long at the base. Each flower is on a pedicel 2.0–4.5 mm (0.079–0.177 in) long, the sepals 3.5–4.0 mm (0.14–0.16 in) long and joined for most of their length. The standard petal is heart-shaped, 5.5–6.0 mm (0.22–0.24 in) long and 6.5–8.0 mm (0.26–0.31 in) wide, and yellow with a dark reddish-brown centre, the wings 4.5–7.0 mm (0.18–0.28 in) long and dark reddish-brown, the keel 4–5 mm (0.16–0.20 in) long and dark reddish-brown. Flowering occurs from July to October and the fruit is a flattened, triangular pod 13–14 mm (0.51–0.55 in) long. [3] [2]

Taxonomy and naming

Daviesia pachyphylla was first formally described in 1863 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae from specimens collected by George Maxwell. [4] [5] The specific epithet (pachyphylla) means "thick-leaved". [6]

Distribution and habitat

Ouch bush grows in heath on laterite between the Fitzgerald River National Park, Ongerup, Ravensthorpe and Munglinup in the Esperance Plains and Mallee biogeographic regions of Southwestern Australia. [3] [2]

Conservation status

Daviesia pachyphylla is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions. [2]
