A considerable genus, spread over tropical Asia and the islands of the Pacific, and of the Madagascar group; all but one of the Australian species are endemic. The genus differs from Melicope, chiefly in the stamens equal to, not double, the number of petals, from Zanthoxylum by the leaves all or mostly opposite, generally by the more valvate petals and more united styles, besides minor characters offering occasional exceptions. (B.Fl. i, 361.)
