Description

The spinescent shrub typically grows to a height of 0.2 to 0.6 metres (0.7 to 2.0 ft)[1] with hairy, intricate branchlets with axillary spines that are 8 to 18 mm (0.31 to 0.71 in) in length which occur singly in the nodes. The blue-green to grey-green leaves are composed of one pair of pinnae that are about 2.5 mm (0.098 in) in length that have two to four pairs of pinnules that usually have an obovate to narrowly oblong-obovate shape and are 2 to 5 mm (0.079 to 0.197 in) in length and 1 to 2 mm (0.039 to 0.079 in) wide.[2] It blooms from June to July and produces yellow flowers.[1] The simple inflorescences are found over halfway up an axillary spine and have spherical flower-heads containing 13 to 25 yellow coloured flowers. The glabrous seed pods that form after flowering have a length of 3 to 8 cm (1.2 to 3.1 in) and a width of 7 to 12 mm (0.28 to 0.47 in) and are sometimes covered in a fine white powdery coating. the turgid seeds inside have an elliptic to circular shape with a length of 3 to 4 mm (0.12 to 0.16 in).[2]

Taxonomy

The shrub belongs to the Acacia pulchella group of wattles and is similar in appearance to Acacia epacantha.[2]

Distribution

It is native to an area in the Wheatbelt region of Western Australia where it is typically found on sandplains growing in sandy soils.[1] It has a disjunct distribution with population found near Toodyay, Cervantes and Eneabba where it is usually a part of heathland or Corymbia calophylla forest communities.[2]
