Beaufortia macrostemon, commonly known as Darling Range beaufortia, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a low shrub with muliple stems, hairy young leaves and three stamens in each stamen bundle.
Description
Beaufortia macrostemon is a shrub with multiple branches at the base, usually 0.2–0.5 m (0.7–2 ft) tall. Its leaves are arranged in opposite pairs, linear to lance-shaped, 10–12 mm (0.4–0.5 in) long, 1–2 mm (0.04–0.08 in) wide and hairy, at least when young. It is one of the few beaufortias with a lignotuber.[2][3]
The flowers are mostly red and are arranged in heads on the ends of the branches. There are 5 sepals, 5 small petals and 5 bundles of stamens. The stamen bundles are pale yellow brown to red, 7–12 mm (0.3–0.5 in) long and hairy near the base. There are 3 stamens in each bundle and the free parts are bright red, 3–7 mm (0.1–0.3 in) and separate at a single point. Flowering occurs from September to January and is followed by fruit which are woody capsules, 10 mm (0.4 in) long and wide, joined in bundles. [2][3]
Taxonomy and naming
Beaufortia macrostemon was first formally described in 1839 by the English botanist John Lindley in A Sketch of the Vegetation of the Swan River Colony.[1][4] The specific epithet (macrostemon) is derived from the Ancient Greek makros meaning "large" or "long" and stemon meaning "thread" or "filament".[5]
Distribution and habitat
Darling Range beaufortia usually grows in gravelly soil derived from laterite and is most common on and near the Darling Scarp in the Jarrah Forest and Swan Coastal Plain biogeographic regions.[3][6]
Conservation
Beaufortia macrostemon is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[3]
