Acacia podalyriifolia is a perennial tree which is fast-growing and widely cultivated. It is native to Australia but is also naturalised in Malaysia, Africa, India and South America. Its uses include environmental management and it is also used as an ornamental tree. It is very closely related to Acacia uncifera. It grows to about 5 m (16 feet) in height and about the same in total width. It blooms during winter.

Common names for it are Mount Morgan wattle, Queensland silver wattle, Queensland wattle, pearl acacia, pearl wattle and silver wattle.

Description

The tall shrub or small tree typically reached a height and width of around 2 to 6 m (6 ft 7 in to 19 ft 8 in). Like most species of Acacia it has phyllodes rather than true leaves. It has grey coloured, smooth or finely fissured bark with terete and hairy branchlets that are often covered with a fine white powdery coating. The silver-grey to grey-green coloured phyllodes have a broadly elliptic to ovate shape and a length of 2 to 5 cm (0.79 to 1.97 in) and a width of 10 to 25 mm (0.39 to 0.98 in) and have hairs on margins and a prominent midvein. It blooms throughout they year producing simple inflorescences in groups of 8 to 22 along an axillary raceme with an axis length of 2 to 11 cm (0.79 to 4.33 in) with spherical flower-heads that have a diameter of 5 to 8 mm (0.20 to 0.31 in) and contain 15 to 30 bright golden flowers.

Taxonomy

The species was first formally described by the botanist George Don in 1832 as part of the work General History of Dichlamydeous Plants. It was reclassified as Racosperma podalyriifolium by Leslie Pedley in 1987 then transferred back to genus Acacia in 2014. Other synonyms include Acacia podalyrifolia.

Distribution

In Australia it is endemic to parts of south eastern Queensland and the north east of New South Wales in areas to the north of Legume but has become naturalised further south where it is found in open woodland or forest communities. It has also become naturalised in Western Australia and South Australia.
