Acacia laricina is a shrub belonging to the genus Acacia and the subgenus Phyllodineae that is endemic to south western Australia.
The shrub typically grows to a height of 0.25 to 0.5 metres (0.8 to 1.6 ft)[2] and can have a dense or spreading or domed habit. It has branchlets that can be covered in a fine, white powdery coating and are hairy at the extremities with linear to triangular stipules that are 3 to 6 mm (0.12 to 0.24 in) in length. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen phyllodes are crowded and appear to be continuous with the branchlets. They are straight to shallowly curved with a pentagonal cross-section and a length 15 to 50 mm (0.59 to 1.97 in) and a width of 0.7 to 1.7 mm (0.028 to 0.067 in) with five prominent nerves.[3] It produces cream-yellow flowers from October to November.[2] The simple inflorescences occur singly in the axils an have sperical flower-heads that contain 17 to 30 cream to pale yellow coloured flowers. Following flowering thinly coriaceous seed pods are formed. The red-brown pods have a length up to around 4.5 cm (1.8 in) and a width of 2 to 4 mm (0.079 to 0.157 in) and are curved and coarsely striated. The subshiny brown seeds inside have an oblong to oblong-elliptic shape with a length of 3.5 to 4 mm (0.14 to 0.16 in) and a conical terminal aril.[3]
