Xylosma serrata, the brushholly, is a species of flowering plant in the family Salicaceae. It is endemic to the island of Montserrat. It was known from only a single location on the south of the island, and this has now been covered by pyroclastic flows from the volcanic eruption. It is therefore possibly extinct, but assessed by the IUCN as critically endangered because of the lack of data.
