Vernacular names

Acacia multisiliqua is a shrub or tree of the genus Acacia and the subgenus Plurinerves that is endemic to northern Australia.


The spindly shrub or slender tree typically grows to a height of 1 to 5 metres (3 to 16 ft)[3] that has a prostrate habit in open coastal situation. Like most species of Acacia it has phyllodes rather than true leaves. The leathery and evergreen phyllodes have an oblong-elliptic to narrowly elliptic shape that is usually incurved a little. The phyllodes have a length of 3 to 7 cm (1.2 to 2.8 in) and a width of 4 to 10 mm (0.16 to 0.39 in) and have one to three longitudinal main veins with a few others that are more obscure.[4] It blooms from February to August and produces yellow flowers.[3] The simple inflorescences present as spherical flower-heads with a diameter of 4 to 6 mm (0.16 to 0.24 in) containing 25 to 40 golden colured flowers. The chartaceous seed pods that form after flowering are linear but raised over and constricted between each of the seeds. The pods have a length of up to around 6.5 cm (2.6 in) and a width of 3 to 7 mm (0.12 to 0.28 in). The dull black seeds inside have an elliptic to oblong-elliptic shape with a length of 4.5 to 5.5 mm (0.18 to 0.22 in) and a club shaped aril.[4]

The plant is allied with Acacia burrana, Acacia complanata and Acacia simsii.[4]

It has a scattered distribution and is native to an area in the Northern Territory, the Kimberley region of Western Australia,[3] and northern Queensland where it is commonly situated on rocky or stony slopes growing in alluvium or over sandstone or soils composed of laterite in drier areas it is usually found as a part of open woodland communities. The range of the plant extends from around Derby in the west across the top end of the Northern Territory and to around Cape Melville in North Queensland in the east and as far south as Clermont.[4]
