Acacia ataxiphylla, commonly known as the large-fruited Tammin wattle,[1] is a shrub belonging to the genus Acacia. It is native to Western Australia.[3]

The shrub typically grows to a height of 0.15 to 0.6 metres (0.49 to 2.0 ft).[3] Phyllodes are continuous with branchlets but without forming cauline wings. They are narrowly linear and straight to shallowly curved or shallowly sigmoid in shape. Typically they are 15 to 60 millimetres (0.6 to 2.4 in) long and 1 to 2 mm (0.04 to 0.08 in) wide and shallowly recurved to uncinate at the apex.[4]

It produces white-cream flowers from June to January.[3] The inflorescences are simple with one per axil and with peduncles 4 to 12 mm (0.16 to 0.47 in) long. They have hairy heads globular to slightly obloid containing 15 to 20 flowers. Flowers are 5-merous with united sepals and petals 2 to 3 mm (0.08 to 0.12 in) long. Reddish-brown pods form later, they are narrowly oblong and curved up to 20 mm (0.79 in) long and 4 mm (0.16 in) wide[4]

The shrub grows in sand, gravel, clay or loam, and has a disjunct scattered population through the Wheatbelt and Great Southern regions of Western Australia.[3] It grows over laterite in low heath, shrub mallee and low Eucalyptus woodlands.[5]

Two varieties are recognized:

  • Acacia ataxiphylla var. ataxiphylla
  • Acacia ataxiphylla var. muricata
