Taxonomy

The species was first formally described by the botanists Mary Tindale and Arthur Bertram Court in 1990 as part of the work Acacia blayana, a new species from the South Coast of New South Wales (Acacia sect. Botrycephalae: Fabaceae) as published in the journal Telopea. It was later reclassified as Racosperma blayanum by Leslie Pedley in 2003 then returned to the genus Acacia in 2006.[4] The type specimen was collected by John Blay in 1982 in the Brogo River catchment to the west of Cobargo.[3] The species is named for the author and collector John Blay.[1]

Distribution

A. blayana is found only on the eastern side of the Great Dividing Range at Wadbilliga National Park in steep mountainous country.[3] The habitat is shallow rocky soils with relatively tall eucalyptus trees nearby. It is a rare plant with a ROTAP rating of 2RC-.[1] It occurs in pure stands and is sometimes associated with Acacia mearnsii or with species of Eucalyptus and Tristaniopsis laurina.[3]
