In the western Indian Ocean islands, which include Madagascar, the Mascarene, Mayotte and Comoros, taxonomic research of the major pantropical family Annonaceae is outdated. Based on a taxonomically verified database of 2,794 georeferenced botanical collections (2,752 from Madagascar), 110 native Annonaceae taxa (106 species) belonging to 9 genera are recorded for this region. A total of 106 native taxa (102 species) are recorded from Madagascar (105 taxa endemic), including a newly described species of Fenerivia Diels. Five species are recorded from Comoros, Mayotte and the Mascarene islands. Huberantha humblotii (Cavaco & Keraudren) Chaowasku is the only non-endemic Malagasy species sharing its distribution with Comoros. We make five new combinations, transferring four species from Popowia Endl. into Sphaerocoryne (Boerl.) Scheff. ex Ridl. and one Uvaria L. species into Huberantha Chaowasku. Finally, 43 names are lectotypified. The genus Popowia is now no longer present in Madagascar, being restricted to Southeast Asia. The genus Xylopia L. is the most diverse in Madagascar with 30 species, followed by Uvaria (21 spp.) and Monanthotaxis Baill. (13 spp.). Endemic Malagasy genera include Fenerivia with 11 species and Ambavia Le Thomas (2 spp.). The history of botanical collections reflects Madagascar's political and socioeconomic changes. Initial collections were sparse during the royal period but increased significantly during the colonial and post-independence eras. Future research should focus on Ambavia, Fenerivia, Monanthotaxis, Sphaerocoryne and Uvaria, which will prove important for better understanding Madagascar's Annonaceae diversity.
