Alstonia boonei
''Alstonia boonei'' is a very large, deciduous, tropical-forest tree belonging to the dogbane family, Apocynaceae. It is native to tropical West Africa, with a range extending into Ethiopia and Tanzania. Its common name in the English timber trade is ''cheese wood'', ''pattern wood'' or ''stool wood'' (see Ashanti Empire golden stool) while its common name in the French timber trade is "emien" (derived from the vernacular of the Ivory Coast).
The wood is fine-grained, lending itself to detailed carving; the tree also finds many uses in folk medicine. Like many other members of the Apocynaceae (a family rich in toxic and medicinal species), ''A. boonei'' contains alkaloids and yields latex.〔Burkhill H.M.
