Acacia hylonoma, commonly known as Yarrabah wattle,[1] 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 in height with a trunk that is dbh with yellowish brown coloured bark.[1] 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 and a width of and have sox to eleven main nerves with many longitudinally anastomosing minor nerves in between.[2]
It is native to a small area in northern Queensland just south east of Cairns where it is a part of rainforest communities.[2] It is found in only a few localities that range in altitude from sea level up to in well developed upland and lowland rain forest. It grows well in disturbed areas and is a component of rain forest regrowth.[1]
The first use of hylonoma as a specific epithet was in 1916 for Salix hylonoma,[3] where the epithet is described as being derived from the Greek, hylonomos, and means "living in woods"[4]
