Adansonia, sér. 3, 37 (2): 277-345. http://dx.doi.org/10.5252/a2015n2a2 ABSTRACT Trees in the genus Canarium L. are known to comprise an important component of the structure of Madagascar’s moist forests, but recent work on Canarium in Madagascar reveals that the genus also comprises an important part of their diversity as well. To date, published Floras for Madagascar have recognized only three taxa of Canarium, but here we recognize 33 species, 27 of them new to sci- ence; this increases the number of accepted species in the genus by 33% worldwide and establishes Madagascar as a primary center of diversity for the genus. Despite its name, C. madagascariense Engl. proves to be one of the rarest and geographically most restricted species. Most Malagasy Canarium species are narrow endemic, and this is consistent with recent floristic and taxonomic research in other KEY WORDS taxonomic groups on the island. The species of Canarium in Madagascar can be distinguished using biodiversity, mostly vegetative characters, and this will prove useful to foresters, ecologists, and conservationists.
