M.Sc. (Botany) / Morphological, anatomical, palynological, cytological, phenological and geographical evidence are used to investigate relationships between the species of Anginon. These characters are discussed and illustrated. Characters of' the genus Glia Sond. were also studied and the genus is shown to be an obvious outgroup in a phylogenetic analysis. Despite the paucity of characters and the variability of character states in the genus Anginon, it is possible to give here a summary of character evolution as interpreted within the genus and also an explicit hypothesis (cladogram) of phylogenetic relationships amongst the species. Especially, the study of the fruit anatomy has resulted in a better understanding of taxonomic relationships at the generic and infrageneric levels. A formal taxonomic treatment is presented, including a key to the species, correct nomenclature, typification, descriptions and distribution maps.
