Novon is a peer-reviewed botanical journal whose purpose is to publish articles establishing new nomenclature, including new taxa and new names, for vascular plants and bryophytes. Short papers typifying existing names may also be accepted. Lengthy revisions that primarily describe and discuss known species, while publishing nova incidentally, are not appropriate for Novon. Articles may be written in English or Spanish.
