A new species of Meliaceae, Turraea monticola Bosser, is described from La Réunion. Another species, first described in Olacaceae (Olax thouarsiana Baill.) then transferred by CAVACO & KERAUDREN (1955) to Turraea [(T. thouarsiana Baill.) Cavaco & Keraudren] and presumed to be from Madagascar, is in fact native to the Mascarenes and recognized as Turraea casimiriana in the Flore des Mascareignes (1997).
