Stirlingia latifolia, commonly known as blueboy, is a species of flowering plant endemic to Western Australia.

[3][4] Meanwhile, John Lindley had published Stirlingia paniculata in his 1839 A Sketch of the Vegetation of the Swan River Colony;[5] this would later be shown to be a synonym of S. latifolia.

In 1995, Alex George published a thorough treatment of the Stirlingia for the Flora of Australia series of monographs.

He reduced numerous names to synonymy, including declaring both S. paniculata and variety gracilis to be taxonomically indistinguishable from S. latifolia itself, and therefore synonymous.

[8] The common name blueboy refers to the fact that wall plaster made using sand taken from where S. latifolia occurs turns blue.
