PhyloCode RegNum phylogenetic nomenclature clade name phylogenetic definition


To facilitate preparation of nomenclatural treatments that follow the PhyloCode, we provide here an outline of the requirements in the form of a checklist.  Rules are categorized as pertaining to publication requirements, protologue content, the defined clade name, or the phylogenetic definition.  Two sample protologues are included to illustrate the elements that need to be included to establish a name under the PhyloCode.  In addition, we provide detailed instructions for registering a name in RegNum, as required by the PhyloCode.
