Description edit
Kunzea acicularis is a shrub which grows to a height of up to 2 m (7 ft), with a few erect, irregularly-branched stems which are covered with fine hairs when young. The leaves are egg-shaped with the narrower end towards the base, densely hairy, 3.5–6 mm (0.1–0.2 in) long, about 2 mm (0.08 in) wide, with a stalk less than 1 mm (0.04 in) long.[2][3]
Three to five pink to mauve flowers are arranged in groups on the ends of branches. The flowers are surrounded by hairy, narrow triangular bracts and bracteoles about 3 mm (0.1 in) long and 1 mm (0.04 in) wide. The sepals are about 2 mm (0.08 in) long and hairy and the five petals are 3–4 mm (0.1–0.2 in) long and almost round. There are about 26 stamens which are usually longer than the petals and a style 6–7 mm (0.24–0.28 in) long. Flowering occurs in October and November and is followed by fruit which are hairy urn-shaped capsules with the sepals attached.
Taxonomy and naming edit
This species was first formally described in 2007 by Hellmut Toelken and Gil Craig and the description was published in Nuytsia.[1] The specific epithet (acicularis) is a Latin word meaning "like a needle"[4] referring to the needle-like bracts.[2]
Distribution and habitat edit
This kunzea grows in mallee and heath on hills and slopes north-east of Ravensthorpe in the Esperance Plains biogeographic region.[5]
Conservation edit
Kunzea acicularis is classified as "Threatened Flora (Declared Rare Flora — Extant)" by the Western Australian Government Department of Parks and Wildlife[5] and an interim recovery plan has been prepared.[3]
