Xylosma is a genus of flowering plants in the family Salicaceae. It contains around 100 species of evergreen shrubs and trees commonly known as brushhollies, xylosmas, or, more ambiguously, "logwoods". The generic name is derived from the Greek words ξύλον (xylon), meaning "wood, tree", and ὀσμή (osmé), meaning "smell", referring to the fragrant wood of some of the species. The Takhtajan system places it in the family Flacourtiaceae, which is considered defunct by the Angiosperm Phylogeny Group.
