Toona is a Mahogany family tree native throughout eastern Europe, northern Asia, South East Asia, and Australia. Botanically it is the equivalent of Cedrela which is otherwise native to Central and South America. There are four Toona species (some sources say five), each with their own trade names. Timber from the Asian species are often just called TOON or SURIAN no matter the species. The Australian species is almost always called RED CEDAR.
