• Etymology: "The specific epithet honours Mrs June Gay who generously assisted my research into the genus Prostanthera by voluntarily assisting with the electronic capture of the herbarium-label data of the research material of this genus. She also provided considerable curatorial support for the material of this genus held in the National Herbarium of New South Wales. After a long illness, June died on 30 September, 1997. Her friendship will be deeply missed."
