Abstract
Summary: The Afromontane floristic région is briefly described and examples of its complex biogeographical and evolutionary relationships are given. The origin of disjunctions of the Afromontane flora remains a matter of controversy but current hypotheses based on biogeographic and stratigraphic evidence are examined; the former are found to require some modification while the latter tend to be discordant with the facts. Evidence is presented which indicates a relatively recent southern migratory track between the mountains of East and West Africa, at least for forest trees. The implications for conservation and research arising from the complexity of the Afromontane flora and its outstanding scientific interest are discussed.Résumé: La région floristique d'Afromontagne est brièvement décrite et des exemples de ses relations biogéographiques et évolutives sont données. L'origine de disjonction dans la flore d'Afromontagne reste une matière controversée mais des hypothèeses basées sur des données biogéographiques et stratigraphiques sont examinées; les premières requièrent quelques modifications alors que les secondes semblent discordantes avec les faits. Certaines évidences indiquent une voie de migration vers le Sud relativement récente entre les montagnes d'Afrique de 1'Est et de I'Ouest, tout au moins pour les arbres forestiers. Les implications pour la conservation et la recherche dues è la complexité de la flore d'Afromontagne et l'intérêt scientifique qui en découle sont discutés.Keywords
