Occurrence data from AVH

Sugar brother grows to a height of about three metres. It nearly always has multiple stems. Like most Acacia species, it has phyllodes rather than true leaves. These are green, and may be up to 10 centimetres long and about three millimetres wide. The flowers are yellow, and held in cylindrical clusters up to two centimetres long and five millimetres wide. The pods are papery, about three millimetres wide.

Taxonomy

It was first published by Joseph Maiden in 1920, based on a specimen collected by Leonard Clarke Webster near Coolgardie in 1900, and a description of the fruit near Kunonoppin supplied by Frederick Stoward. The specific name is in reference to the town of Coolgardie.

There are three recognised subspecies:

• A. c. subsp. coolgardiensis
• A. c. subsp. effusa
• A. c. subsp. latior
