African mahogany species don't hybridize, says new study

A new study on genetic diversity and differentiation among species of African mahogany (Khaya spp.) was published recently in the journal Conservation Genetics (20, 1035–1044), as part of collaborative work between the CGIAR Research Program on Forests, Trees and Agroforestry, the French Agricultural Research Centre for International Development, ITTO and other partners. The study of 2222 species in five or six Khaya species (depending on classification) found little evidence of hybridization, and the vast majority of individuals were assigned to the same species group as identified using morphological characters.
