This is the fifth title in the series Repatriation of Kew Herbarium Data for the Flora of Northeastern Brazil. In total 184 species are recorded in 18 genera for the whole of the Myrtaceae, arranged alphabetically and sorted by state, collector and number. A full exsiccatae list (an alphabetical list of collector and collector’s number) allows curators, students and researchers to name a duplicate collection lodged in any herbarium in the world to be checked against the determination of that collection at the Royal Botanic Gardens, Kew.
