Psiloxylon mauritianum (known locally as "bois bigaignon") is a species of flowering plant, the sole species of the genus Psiloxylon. It is endemic to the Mascarene Islands (Mauritius and Réunion) in the Indian Ocean.[1]

It is a white-barked evergreen tree, bearing essential oils. It is dioecious,[1] with male and female flowers on separate individuals. It is traditionally used as a medicinal plant, and appears contain compounds that inhibit the growth of Staphylococcus aureus.[1]

It was formerly placed alone in family Psiloxylaceae, but is now considered a basal member of the family Myrtaceae.[2]
