Acacia lumholtzii

Acacia lumholtzii, also known as Girringun wattle, is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to a small area of north eastern Australia. It is listed a vulnerable according to the Nature Conservation Act 1992.

Description
The shrub typically grows to a height of 2 to 4 m and has cream coloured and lenticellate bark with ribbed branchlets covered in dark brown hairs. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen phyllodes have a linear but are narrowed toward the base and have a length of 8 to 11 cm and a width of 3 to 4 mm and mostly have seven prominent but widely spaced longitudinal nerves.

Taxonomy
The species was first formally described in 2006 by the botanist Leslie Pedley as part of the work ''Notes on Acacia Mill. (Leguminosae: Mimosoideae), chiefly from Queensland as published in the journal Austrobaileya''.

Distribution
It is confined to small area in Girringun National Park on Bishop Peak located to the south of Cardwell in Queensland where it is often situated on rack pavements and cliffs composed of granite.
