Acacia concurrens

The shrub can grow as high as 10 m (33 ft) but is typically smaller. The glossy green phyllodes have an obliquely obovate shape with the lower margin that is almost straight.[3] It has fissured and fibrous, grey-black coloured bark and stout, angular branchlets The phyllodes have a length of up to 16 cm (6.3 in).[2] It blooms between March and September producing rod shaped flowers are bright yellow that are found in pairs in the leaf axils.[3] The flower-spikes are around 3.5 to 11 cm (1.4 to 4.3 in) in length. The linear, slightly moniliform, semicircular seed pods that form after flowering are 5 to 10 cm (2.0 to 3.9 in) in length. The pods contain brownish black seeds with an elliptic shape that are 3.5 to 4.5 mm (0.14 to 0.18 in) in length.[4]

The species was first formally described by the botanist Leslie Pedley in 1974 as part of the work Contributions from the Queensland Herbarium . It was reclassified as Racosperma concurrens in 1986 by Pedley then transferred back to genusAcacia in 2001.[5]

It is endemic to an area from south eastern Queensland in the north to northern New South Wales in the south[3] where it is common in coastal areas from around the Mooloolah River in Queensland down to the Hastings River in New South Wales[4] on hillsides or plateaux growing in sandy or stony sandy loams often over shale as part of the understorey in Eucalyptus forest communities.[2]
