The taxonomy of fifty-five species of Acacia, primarily Western Australian, in section Phyllodineae (Leguminosae: Mimosoideae) as published in the journal Nuytsia . It was briefly reclassified as Racosperma mutabile in 2003 by Leslie Pedley then transferred back into the genus Acacia in 2006. [3]
There are five recognised subspecies.
