Method steps

1. A database of Annonaceae collections from Cameroon was generated in which we recorded collector number, location, coordinates, region and herbarium where the specimens are deposited. A collection represents a herbarium sample identified by having the same collector and number (when present). It may be composed of one or more specimens, and such duplicates can be deposited in different herbaria. We used several sources as primary data providers to build the database. The initial database was based on data extracted from the “Réseau Informatique des Herbiers d’Afrique” (RIHA). This database contains all specimens held in the Herbier National du Cameroun/National Herbarium of Cameroon. We extracted all Annonaceae from Cameroon. We then supplemented this database with other available databases: BRAHMS (Naturalis Biodiversity Center, Leiden, The Netherlands); TROPICOS (Missouri Botanical Garden, St Louis, USA); Kew Database (Royal Botanical Gardens, Kew, UK and other databases (T.L.P. Couvreur (IRD); V. Droissart (IRD); D.J. Harris (E); N. Kamdem (Université de Yaoundé I)). As much as possible specimens were checked in herbaria to confirm their identification. Thus, the database contains specimens that we have seen and confirmed, and others which we did not see. For genera with recent taxonomic revisions, determinations were updated (Chatrou 1998, Versteegh and Sosef 2007, Couvreur 2009, 2014, Botermans et al. 2011, Fero et al. 2014, Ghogue et al. 2017, Gosline et al. 2018, Johnson and Murray 2018). Collections of which at least one specimen was seen, are marked with () before the herbarium acronym(s) in the specimen citation section for each species. For specimens not seen or confirmed, the original identification was retained pending a name update if needed (synonym, new combination, etc.).
