Description

The shrub typically grows to a height of 0.2 to 2 metres (0.7 to 6.6 ft).[1] The pinnae form in pairs along the branchlet. The proximal pinnae are 1 to 4 millimetres (0.04 to 0.16 in) in length while the distal are 2 to 30 mm (0.08 to 1.18 in) long.[2] It blooms from May to November and produces cream-yellow flowers.[1] Each inflorescence is simple forming one or two per axil. The heads have a globular shape that is sometimes obloid with a diameter of 4 to 6 mm (0.16 to 0.24 in) composed of 12 to 21 flowers. Following flowering it will form green, glabrous narrowly-oblong seed pods with a length of 1 to 4.5 cm (0.4 to 1.8 in) and 5 to 9 mm (0.20 to 0.35 in) wide. the brown seeds have an oblong to elliptic shape and are 2 to 4 mm (0.08 to 0.16 in) long.[2]

Classification

The species was first formally described by the botanist Heinrich Wendland in 1819 as part of the work Flora: oder Allgemeine Botanischer Zeitund. Synonyms for this species include Acacia strigosa and Racosperma brownianum.[3]

There are five varieties:

  • Acacia browniana var. browniana
  • Acacia browniana var. endlicheri
  • Acacia browniana var. glaucescens
  • Acacia browniana var. intermedia
  • Acacia browniana var. obscura

Distribution

The plant is found in wet areas, near such as around streams and rivers, also on flats and ridges, hills and among granite outcrops[1] in south western Western Australia from around Bindoon and Mogumber in the north around the coast to Augusta in the south and Manypeaks.[2] It grows well in sandy, loamy, gravelly soils often containing laterite.[1]
