Acacia maranoensis

The tree can grow to a height of around 10 m (33 ft)[1] and has furrowed dark grey bark.[2] It has glabrous branchlets that are scurfy with deposits of white resin. Like most species of Acacia it has phyllodes rather than true leaves. The leathery grey-green coloured phyllodes have a linear to narrowly elliptic shape are straight to slightly curved with a length of 9 to 20 cm (3.5 to 7.9 in) and a width of 4 to 12 mm (0.16 to 0.47 in) and have many closely parallel nerves of which one to three are more prominent than the others.[1]

The species was first formally described by the botanist Leslie Pedley in 1978 as part of the work A revision of Acacia Mill. in Queensland as published in the journal Austrobaileya. It was reclassified by Pedley as Racosperma maranoense in 1987 then transferred back to genus Acacia in 2001.[3]

The plant has a limited range in the Roma and Mitchell area of southern Queensland where it is found growing in texture contrast soils often as a part woodland communities featuring stands of Eucalyptus populnea.[1] It is found in the Maranoa Region including around Morven and is also found to the west of Kingaroy. It is commonly situated on plains or flat terrain, that can be periodically inundated following rainfall events growing in dark brown, heavy clay loamy soils that usually are quite boggy once wet.[4]

It can be used as a street tree and shade tree that has a fast growth rate and is tolerant of a light frost and drought. It can grow in a range of soils including soils that are mildly acidic or alkaline or enriched that are dry for extended periods to infrequently flooded.[2]
