Acacia hylonoma Pedley

Austrobaileya 1(2): 214. 1978

Acacia hylonoma, commonly known as Yarrabah wattle,[4] is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to a small area of north eastern Australia.


The tree can grow to be as tall as 15 m (49 ft) in height with a trunk that is 20 cm (7.9 in) dbh[5] with yellowish brown coloured bark.[4] It has glabrous and lenticellate branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The thinly leathery, glabrous and evergreen phyllodes have a narrowly elliptic shape and are straight to shallowly recurved. The phyllodes have a length of 8 to 15 cm (3.1 to 5.9 in) and a width of 7 to 25 mm (0.28 to 0.98 in) and have sox to eleven main nerves with many longitudinally anastomosing minor nerves in between.[5]

It is native to a small area in northern Queensland just south east of Cairns where it is a part of rainforest communities.[5] It is found in only a few localities that range in altitude from sea level up to 400 m (1,300 ft) in well developed upland and lowland rain forest. It grows well in disturbed areas and is a component of rain forest regrowth.[4]

The first use of hylonoma as a specific epithet was in 1916 for Salix hylonoma,[6] where the epithet is described as being derived from the Greek, hylonomos, and means "living in woods"[7]
