Description

The shrub typically grows to a height of 0.3 to 2 metres (1 to 7 ft)[1] and has a dense and intricate habit. It has glabrous with persistent and spinose stipules with a length of 1 to 3 mm (0.039 to 0.118 in). Like most species of Acacia it has phyllodes rather than true leaves. The evergreen, sessile phyllodes that are usually continuous with the branchlets have a length of 2 to 5 cm (0.79 to 1.97 in) and a diameter of 0.7 to 1 mm (0.028 to 0.039 in). The rigid, glabrous and pungent phyllodes have a total of eight distant and raised nerves with three nerves on each face when flat.[2] It blooms from August to September and produces yellow flowers.[1]

Taxonomy

There are two recognised subspecies:

• Acacia chapmanii subsp. australis
• Acacia chapmanii subsp. chapmanii

Distribution
