Systématique et taxonomie des Sapotaceae de Madagascar

Depuis la publication de la famille des Sapotacae dans la Flore de Madagascar (Aubréville 1974) qui recense 11 genres et 85 espèces, de nombreuses nouvelles récoltes ont amené la nécessité de revoir la taxonomie proposée. De nombreuses nouvelles espèces sont suspectées, ainsi que de nombreuses synonymies. La conception générique en vigeur dans la famille (Pennington, 1991) a déjà conduit à regrouper trois genres dans Chrysophyllum (Schatz & Gautier, 1996). Elle est actuellement en cours de réévaluation sur des bases moléculaires par des équipes à E et à S (Swenson & Anderberg, 2005) et d’autres changements sont attendus amenant une stabilité propice à un traitement durable au niveau spécifique.

After a first assessment of the level of knowledgeon Madagascar Sapotacea conducted in the framework of Madagascar Vascular Plants Catalogue (Missouri Bot. Gard.), this projects aims at revising the systematics of the family for Madagascar taxa. At generic level, the goal is to elucidate the hitherto obscure relationships between the Malagasy endemic genera by identifying their closest relatives in Africa as well as Indo-Malyaysia, and to reassess the validity of the generic concepts in collaboration with teams in Edinburgh and Stokholm. In parallel taxonomic revision of all Madagasca Sapotaceae will be conducted, starting with genera whose monophyly is not in question and continuing with others, as the generic concepts become more sound.
