Acacia burbidgeae

The shrub has an erect to spreading habit and typically grows to a height of 2 metres (7 ft)[1] but reach as a high as 4 m (13 ft). The sparsely hairy branchlets are slightly resinous. The often subcrowded, slender, slightly incurved to straight phyllodes are usually patent to ascending and have a length of 15 to 40 mm (0.59 to 1.57 in) and a width of 0.6 to 1 mm (0.024 to 0.039 in).[2] It blooms from June to October and produces yellow flowers.[1] The simple inflorescences are found with one per node. The spherical flower-heads contain 20 to 30 golden flowers. The linear brown seed pods that form after flowering are up to 6.5 cm (2.6 in) in length and around 3 mm (0.12 in) wide.[2]

The species was first formally described by the botanist Leslie Pedley in 1979 as part of the work A revision of Acacia Mill. in Queensland, Part 2 as published in the journal Austrobaileya. Pedley reclassified it as Racosperma burbidgeae but it was transferred back into the genus Acacia in 2001.[3] The specific epithet honours Nancy Tyson Burbidge, an Australian botanist.[1] A. burbidgeae belongs to the Acacia johnsonii group and is most closely related to A. johnsonii , Acacia pilligaensis and Acacia islana.[2]

It is found in north eastern parts of New South Wales around Emmaville and to the south of Torrington and extending into south eastern parts of Queensland where it is a part of dry sclerophyll forests growing in sandy granitic soils.[1] In Queensland its range extends from Cunnamulla in the west to St George in the east and Chinchilla in the north.[2]
