Acacia microsperma

The green to grey-green, slightly hairy and evergreen phyllodes have a linear shape and are quite straight with a length of 7 to 14 cm (2.8 to 5.5 in) and a width of 1.5 to 4 mm (0.059 to 0.157 in) and have multiple obscure, closely parallel nerves.

[1] When it blooms it produces inflorescences that appear in groups of one to four with spherical flower-heads that have a diameter of 4 to 5 mm (0.16 to 0.20 in) and contain 20 to 40 golden coloured flowers.

The brown seeds inside have a narrowly elliptic shape with a length of 2.5 to 4 mm (0.098 to 0.157 in) and have a fleshy aril that is repeatedly folded.

[1] The species was first formally described by the botanist Leslie Pedley in 1974 as a part of the work Contributions from the Queensland Herbarium.

[3] The tree has a scattered distribution across southern Queensland with a range that extends from around Adavale in the north west down to around the New South Wales border around Talwood where it is found growing in clay to shallow loamy soils over weathered rock as a part of open woodland along with Acacia cambagei or Eucalyptus thozetiana or sometimes forming dense stands of its own.
