THE GENUS ERIOGONUM MICHX. (POLYGONACEAE) AND MICHEL GANDOGER James L. Reveal' Abstract.— Michel Gandoger, a notorious "splitter," proposed several new entities in the plant genus Eriogonum (Polvgonaceae) in a 1906 paper published in Belgium. Because he used the term species at two different ranks, in violation of the International Code of Botanical Nomenclature, manv of his names are invalid. Unlike his papers published in France, this one was apparentl\- edited so that some names were validly published and some are invalid. A review of the 1906 Eriogonum paper shows that a majority of both specific and infraspecific entities proposed are valid, but some names, long in use and assinned to be valid, are, in fact, invalid. Even so, most of his names are sviionyms. Each name proposed by Gandoger is reviewed and a nomenclatural and taxonomic disposition made. Two new combinations are made within E. hitcolum Greene, var. caninum (Greene) Reveal and var. pedunrulatum (S. Stokes) Reveal. Michel Gandoger (1850-1926), in the ond order, in addition to terming them "spe- words of Keck (1958), was a "French abbe; ciebus secimdi ordinis," he also used the term author of 'Flora Europae' (27 vols.); volumi- siibspeciebus or subspecies to refer to entities nous writer; amasser of a huge herbarium he then proceeded to treat as binomials and now at Lyon; a 'splitter' who named thou- to designate by the expression sp. n. sands of unacceptable species."
