Dear Ronaldo,

we are currently working on an extension of the Meliaceae phylogeny including more taxa and DNA regions. Cedrela and Toona are probably a monophyletic group, and Swietenia and Khaya seem to be among the closest relatives to this clade.

Concerning our current work on the fine-scale relationships in the tribe Cedreleae (= Cedrela and Toona sensu Pennington & Styles 1975), our sampling covers the whole distribution range of Cedrela and all its species, and results will be available by next year.

Kind regards,
