Novon is a quarterly, 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.

Manuscripts submitted to Novon must follow guidelines in the Checklist for Authors, which can be obtained by clicking on Submissions or as a PDF on the MBG Press website: The rationale for publication of new nomenclature must be clearly explained; new taxa should be differentiated from similar species by textual comparisons, keys, and/or illustrations. Novon will not knowingly accept simultaneous submissions or manuscripts presenting work previously published elsewhere.
