Weinmannia species from Madagascar are currently difficult to identify with available published accounts due to both a paucity of qualitative characters used in identification keys, and a large number of undescribed species. However, newly recognized morphological characters, especially of the inflorescence, can be used to diagnose Malagasy sect. and species-groups. These characters, used previously for a comprehensive cladistic analysis of the genus Weinmannia (Bradford 1998), are applied here in diagnoses and a key to the resulting sections and species-groups of Weinmannia in Madagascar.
