Acacia epacantha (Maslin) Maslin

Nuytsia 2 (6): 359 (1979).

Acacia epacantha is a shrub of the genus Acacia and the subgenus Pulchellae that is endemic to an area in the south west of Australia.


The dense bushy spiny shrub typically grows to a height of 0.2 to 0.5 metres (0.7 to 1.6 ft)[1] and has a spreading habit with branchlets that have axillary 1 to 2 cm (0.39 to 0.79 in) long spines that around found singly on each node. The single pair of pinnae have a length of 1 to 2 mm (0.039 to 0.079 in) and have two pairs of pinnules with a length of 6 to 10 mm (0.24 to 0.39 in) and a width of 0.7 to 1.5 mm (0.028 to 0.059 in).[2] It blooms from July to August and produces yellow flowers.[1]

The species was first formally described by the botanist Bruce Maslin in 1979 as a part of the work Studies in the genus Acacia (Mimosaceae) - 9 Additional notes on the Series Pulchellae Benth. as published in the journal Nuytsia. It was reclassified as Racosperma epacanthum in 2003 by Leslie Pedley then transferred back to genus Acacia in 2006.[3]

It is native to an area on the west coast in the Wheatbelt region of Western Australia where it is commonly found growing in gravelly lateritic loam or clay soils.[1]
