Acacia pustula is a tree belonging to the genus Acacia and the subgenus Phyllodineae native to north eastern Australia.

Description[]

The tree can grow to a height of up to 15 metres (49.2 ft) with glabrous dark-reddish coloured branchlets that are angled at extremities. Like most species of Acacia it has phyllodes rather than true leaves. The variable, evergreen phyllodes have a linear to narrowly elliptic shape. They have a length of 5.5 to 14.5 cm (2.2 to 5.7 in) and a width of 2 to 14 mm (0.079 to 0.551 in) and are wider on young plants and appear narrower on mature plants and similar to Acacia angusta.[1] It blooms during the winter from around May to July[2] and it produces racemose inflorescences along an axis of 1 to 9 cm (0.39 to 3.54 in) and have spherical flower-heads containing 18 to 25 golden coloured flowers. After flowering thinly coriaceous, mid-brown coloured, linear seed pods form that are linear but slightly raised over seeds. The glabrous pods have a length of up to around 12 cm (4.7 in) and a width of 5 to 7 mm (0.20 to 0.28 in) containing longitudinally arranged seeds. The slightly shiny black seeds have an oblong to elliptic shape with a length of 5 to 6 mm (0.20 to 0.24 in) with a clavate aril.[1]

Taxonomy[]

The specific epithet is Latin in origin and means blister or pimple-like in reference to the prominence of the marginal gland on the phyllode.[2]

Distribution[]

It is endemic to south eastern Queensland where the bulk of the population is found between Cracow, Condamin, Kingaroy and Eidsvold with scattered smaller populations in the Carnarvon National Park and . where it grows in sandy to sandy loam soils over sandstone as a part of open Eucalyptus woodland communities.[1]
