Acacia argyrotricha is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to north eastern Australia
Description
The shrub typically grows to a height of around 2 m (6 ft 7 in) and has a spreading habit with angular branchlets that are covered in densely appressed hairs. Like most species of Acacia it has phyllodes rather than true leaves. The thick evergreen phyllodes have a flattened linear shape and are straight or slightly sickle shaped. The phyllodes are 10 to 15 cm (3.9 to 5.9 in) in length and 1 to 1.8 mm (0.039 to 0.071 in) wide and multistriate with non-anastomosing nerves. It blooms between September and October producing inflorescences that appear in pairs on a short axillary axis. The spherical flower-heads contain 30 to 40 deep yellow coloured flowers. In December it produces linear shaped seed pods that are raised over the seeds. The pods are up to 7.5 cm (3.0 in) in length and around 2.5 mm (0.098 in) wide. The seeds inside are arranged longitudinally and have an oblongoid shape with a length of 3 to 4 mm (0.12 to 0.16 in) and a width of 1.7 to 2 mm (0.067 to 0.079 in) with a cupular terminal aril.[1]
Taxonomy
The species was first formally described by the botanist Leslie Pedley in 1999 as part of the work Notes on Acacia (Leguminosae: Mimosoideae) chiefly from northern Australia as publishedin the journal Austrobaileya. Pedley the reclassified it as Racosperma argyrotrichum in 2003 and it was transferred back to genus Acacia in 2006.[2]
Distribution
It is native to a small area on Queensland in the Darling Downs district in the Bracker State Forest south of Inglewood where it is found growing in sandy soils as a part of Eucalyptus woodland communities.[1]
