Acacia perangusta

The shrub or small tree typically can grow to a height of around 7 m (23 ft) and has a bushy habit[1] with a width reaching up to 5 m (16 ft).[2] It has slender, glabrous, reddish brown coloured branchlets that are angled at the extremities. Like most species of Acacia it has phyllodes rather than true leaves. The thin, glabrous, evergreen phyllodes have a narrowly linear shape with a length of 4 to 8 cm (1.6 to 3.1 in) and a width of 1 to 1.6 mm (0.039 to 0.063 in). They are occasionally obtuse-mucronate and have a fine midrib fine with few obscure lateral nerves. When it blooms it produces racemose inflorescences along an axis of 2.5 to 4 cm (0.98 to 1.57 in) with small spherical flower-heads that contain 9 to 12 lime yellow coloured flowers. After flowering glabrous seed pods form that are covered in white powdery coating. They are slightly constricted between seeds and convex on opposite sides with a length of up to 7.5 cm (3.0 in) and a width of around 5 mm (0.20 in) with longitudinally arranged seeds inside.[1]

It is endemic to Queensland from around the Burrum Range in the north to around 30 km (19 mi) south east of Brisbane where it is found along small streams and creeks growing in sandy or clay loam soils.[1]
