Description

The tree typically grows to a height of 3 to 8 m (9.8 to 26.2 ft) and has a dense crown with grey to white hairy branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The grey-green hairy phyllodes have a narrowly elliptic shape and are straight to slightly recurved with a length of 4 to 11 cm (1.6 to 4.3 in) and a width of 4 to 16 mm (0.16 to 0.63 in). They have one to three more prominent nerves than the many others that are closely parallel and indistinct in comparison.[2] It blooms between May and August and produces seed pods between September and December.[3]

Taxonomy

The species was first formally described by the botanist Frederick Manson Bailey in 1896 as a part of the work Botany. Contributions to the Flora of Queensland as published in the Botany Bulletin. Department of Agriculture, Queensland. It was reclassified as Racosperma georginae by Leslie Pedley in 1987 then transferred back to genus Acacia in 2001.[4] The specific epithet recognizes the place that the type specimen was collected, along the Georgina River.[3]

Distribution

Georgina gidgee woodlands have a patchy but widespread distribution in central Australia and are considered Vulnerable (VU) according to the IUCN Red List of Ecosystems.[5] It is widely distributed through arid parts of central and eastern Australia from the southeastern Northern Territory in the west extending into Queensland to around the catchment of the Georgina River in the northeast and into the far northeast of South Australia in the southeast, where it is usually situated along water-courses or on plains growing in loamy or clay soils as a part of low open woodland communities.[2]

Uses

Its uses include timber and fuel.[1] Primarily the seed pods can be extremely poisonous, containing fluoroacetate. Sheep and cattle sometimes are poisoned after grazing on the pods.[6]
