Acacia orthotropica
# Acacia orthotropica

Acacia orthotropica, commonly known as Mount Trafalgar wattle, is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to north western Australia.

## Description

The single-stemmed tree can grow to a height of around 4 m (13 ft) and has an obconic habit with glabrous red-brown coloured branchlets. Like most species of Acacia it has phyllodes rather than true leaves. The thinly leathery, erect, crowded and evergreen phyllodes have a narrowly oblong-oblanceolate shape and are quite straight with a length of 3 to 6 cm (1.2 to 2.4 in) and a width of 2.5 to 3.5 mm (0.098 to 0.138 in) with two longitudinal nerves. It blooms around January and produces simple inflorescences found in the axils and made up of spherical flower-heads containing 30 to 35 light golden coloured flowers.

## Distribution

It is native to a small area in the Kimberley region of Western Australia. The limited distribution is confined to a single population within the confines of the Prince Regent National Park where it is a situated on a slope of broken sandstone slope next to a low basalt hill where it is part of an open shrubland community associated with a groind cover of species of Triodia.
