Sumario:Abstract. Phlegmariurusvanuatuensis A.R.Field is described as a new species for plants endemic to the islands of Vanuatu that were previously identified with P.nummulariifolius (Blume) Ching. The Vanuatuan species differs from the widespread Asian-Oceanian species in several characteristics, most notably its acutely divergent leaf arrangement and thicker less branched fertile spikes. Phlegmariurusnummulariifolius is here re-circumscribed as plants occurring in Asia and into Oceania as far east as the Solomon Islands, being replaced eastwards by P.vanuatuensis. In addition, new nomenclatural combinations are made for Phlegmariurusaustralis, a species from Polynesia and for Phlegmariuruscopelandianus, a species from Malesia.
