Distribution: Mostly tropical Asia, especially New Guinea (626), extending to S-Himalaya, Japan, Pacific and Australia. For molecular reasons it is unavoidable to include many previously separated genera (especially Cadetia, Flickingeria and Diplocaulobium), otherwise the genus in traditional sense would be polyphyletic. Any attempts to dismantle it would require worldwide revision and not local treatments.
