Diversity and distribution of Carapa Aubl. (Meliaceae) in Africa.

Carapa is a poorly known genus of the Mahogany family (Meliaceae), which comprises small to medium-sized trees in tropical Africa, Central America, northern South America, and the West Indies. Currently, only one species, Carapa procera, is recognized in Africa. However, there is a general consensus concerning the extreme variability of this species. In order to investigate the patterns of morphological variation in Carapa, we conducted fieldwork in Senegal, Ghana, Cameroon and Gabon to study populations in situ and look for correlations between different characters. Evidence from field observations, and multivariate analysis of floral and vegetative morphological characters taken from herbarium specimens, allowed us to distinguish over 12 species, most of which were described in the past and today placed in synonymy. A key to the identification of the species is provided and their distribution presented.
