Description

Hovea acanthoclada is an upright or prostrate scrambling, stiff shrub to 1.5 m (4 ft 11 in) high, and needle-shaped, hairy stems, mostly spiny. The leaves are oblong, whorled, flat, hairy, 2–5.5 mm (0.079–0.217 in) long and 2–2.6 mm (0.079–0.102 in) wide, margins toothed or lobed, pedicel 2–2.6 mm (0.079–0.102 in) long and hairy. The bracteoles 0.7–1.2 mm (0.028–0.047 in) long and hairy, calyx 4–5.6 mm (0.16–0.22 in) long with simple hairs. The corolla colours vary, mostly blue or violet with occasional markings, standard petal 8–9.5 mm (0.31–0.37 in) long and smooth, wings 7.5–8 mm (0.30–0.31 in) long, keel 5.5–7 mm (0.22–0.28 in) long. Flowering occurs from July to October and the fruit is a dry, smooth pod, 6–7 mm (0.24–0.28 in) long and 9–10 mm (0.35–0.39 in) wide.[2][3]

Taxonomy and naming

Hovea acanthoclada was first formally described in 1863 by Ferdinand von Mueller and the description was published in Fragmenta Phytographiae Australiae.[4][5] The specific epithet (acanthoclada) means "spiny" and "branch".[6]

Distribution and habitat

Thorny hovea grows in lateritic soils in the south-west near Ravensthorpe and gravelly locations near Kalgoorlie.[3]
