Acacia deltoidea is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to north western Australia.
The straggling shrub typically grows to a height of 1.5 to 3 metres (5 to 10 ft) [3] and has glandular-hairy branchlets with persistent subulate upcurved stipules with a length of 1.5 to 4 mm (0.059 to 0.157 in). Like most species of Acacia it has phyllodes rather than true leaves. The subsessile, imbricate phyllodes are patent to ascending with a cuneate to elliptic to triangular or broadly obdeltate shape. The leathery and glabrous phyllodes are 6 to 20 mm (0.24 to 0.79 in) in length and 4 to 7 mm (0.16 to 0.28 in) wide and have three to four distant, slightly raised main nerves. [4] It blooms from March to August and produces yellow flowers. [3]
There are two recognised subspecies:
It is native to an area in the West Kimberley region of Western Australia [3] from along the Bonaparte Archipelago and Napier Bay in the west to around the Phillips Range, Kimberley Downs Station and Beverley Springs Station in the east. [4] It is usually found growing in sandy soils over and around sandstone and quartzite. [3]
