Acacia speckii is a shrub or tree of the genus Acacia and the subgenus Plurinerves that is endemic to a small area in central western Australia.
The bushy rounded shrub or tree typically grows to a height of 1.5 to 3 metres (5 to 10 ft)[1] and has glabrous, cylindrical grey coloured branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The erect and evergreen phyllodes have a threadlike shape and are straight to shallowly incurved and usually bent at the gland. The rigid, glabrous, grey-green phyllodes usually have a length of 8 to 12 cm (3.1 to 4.7 in) and a diameter of 1 to 1.5 mm (0.039 to 0.059 in) and have eight distant, strongly raised nerves.[2] When it blooms it produces simple inflorescences that occur singly or in pairs in the axils with broadly ellipsoid to obloid shaped flower-heads. The glabrous, chartaceous and light brown seed pods that form after flowering resemble a string of beads and have a length up to around 13.5 cm (5.3 in) and a width of 4 to 6 mm (0.16 to 0.24 in) containing spherical dull brown seeds.[2]
Taxonomy
The species was first formally described in 1999 by the botanists Richard Sumner Cowan and Bruce Maslin in 1999 as a part of the work The taxonomy of miscellaneous species with sharply pungent phyllodes in Acacia section Plurinerves (Leguminosae: Mimosoideae) as published in the journal Nuytsia. In 2003 it was reclassified by Leslie Pedley as Racosperma speckii then transferred back to genus Acacia in 2006.[3]
