Ecotypic variation in Symphonia globulifera (Clusiaceae), and its systematic “complications”.
Symphonia globulifera is a species of trees found throughout the tropics and has an amphi-Atlantic distribution - it is widespread throughout sub-saharan Africa as well as the neotropics. According to the latest monographic treatment of the genus, it comprises a single morphological taxon, though it is quite variable across its range. However, this species exhibits elevational ecotypic variation with forms differing markedly in overall habit. Morphometric and DNA analyses of low- and high-elevation ecotypes from Cameroon, French Guiana and Surinam reveal patterns of relatedness that present new questions regarding infraspecific relationships and biogeography.
