Boronia acanthoclada is a plant in the citrus family, Rutaceae and is endemic to a small area in the south-west of Western Australia. It is a low, prickly shrub with small leaves and white, four-petalled flowers.

Description

Boronia acanthoclada is a shrub that grows to a height of about 0.3 m (1 ft) with spreading branches and spiny branchlets. Its leaves are narrow egg-shaped with the narrower end towards the base, 3–6 mm (0.1–0.2 in) long and often clustered on the older wood. The flowers are white and are borne on the ends of short shoots on a pedicel 2–3 mm (0.08–0.1 in) long. The four sepals are narrow triangular, fleshy, glabrous and about 2 mm (0.08 in) long. The four petals are elliptic and about 4 mm (0.2 in) long and the eight stamens are hairy. Flowering occurs in September.[2][3]

Taxonomy and naming

Boronia acanthoclada was first formally described in 1998 by Paul G. Wilson and the description was published in Nuytsia from a specimen collected in the Frank Hann National Park.[4] The specific epithet (acanthoclada) is derived from latinized Greek, acantho- meaning 'spiny' and cladus 'a branch'.[2]

Distribution and habitat

This boronia grows in sand over gravel and is only known from the type collection.[3]

Conservation

Boronia acanthoclada is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife[3] meaning that it is poorly known and from only one or a few locations.[5]

gollark: No, it's been 2 years or so.

gollark: They get them on monthly plans, I generally (have my parents) buy phones, then have to replace them every 1.5-2 years when they randomly fail in some way, probably because I horribly mistreat them?

gollark: My brother has a Nokia phone and my other brother has a Samsung one, both of which they somehow kept for way longer than me.

gollark: I mean, I generally don't think buying phones based only on *brand* is very smart.

gollark: I've *maybe* made a decision I'm maybe satisfied with, but I haven't actually gone through with it because I remain unsure.
