Acacia amputata Maslin

Nuytsia 12(3): 493 (1999), nom. nov.

Acacia amputata is a shrub of the genus Acacia and the subgenus Pulchellae that is endemic to an area of south western Australia.


The spreading spinose shrub typically grows to a height of 0.25 to 0.6 metres (0.8 to 2.0 ft)[1] with pink-brown branches and spiny branchlets that have short stiff hairs. The small leaves contain one pair of pinnae that are 1 to 2 mm (0.039 to 0.079 in) in length and two to four pairs of pinnules. The grey-green and glabrous pinnules have an oblong-obovate to obovate shape with a length of 1 to 2.5 mm (0.039 to 0.098 in) and a width of 0.5 to 1 mm (0.020 to 0.039 in).[2] It blooms from July to September and produces yellow flowers.[1] The rudimentary inflorescences have spherical flower-heads containing 10 to 20 light golden coloured flowers. The thinly crustaceous and glabrous seed pods that form following flowering are undulate to spirally coiled with a length od up to 15 mm (0.59 in) and a width of 4 to 5 mm (0.16 to 0.20 in) and contain mottled brown seeds with a broadly elliptic shape and a length of about 2 mm (0.079 in).[2]

It is native to an area in the Wheatbelt and Great Southern regions of Western Australia where it is commonly situated on undulating plains growing in sandy of gravelly loamy soils.[1] The range extends from Narrogin and Brookton in the west to arouns the Frank Hann National Park in the north east and Boxwood Hill in the south east and it is usually a part of open shrubland or tall open Eucalyptus shrubland communities.[2]
