Abstract
Summary: Philippe, M.: Nomenclature générique des trachéidoxyles fossiles mésozoïques à champs araucarioïdes. ‐ Taxon 42: 74‐80. 1993. ‐ ISSN 0040‐0262.Many studies on fossil woods did not respect the International code of botanical nomenclature. As a result their nomenclature is complex and fluctuating. During preparation of a thesis on Jurassic fossil woods from Franche‐Comté (northeastern France), problems have arisen with the nomenclature of gymnospermous woods with araucarioid cross‐field pitting. This work is a nomenclatural review of the twenty‐one generic names that have been used to designate mesozoic tracheidoxyls with araucarioid cross‐fields. Only eight are legitimate and can be justifiably used. As a taxonomic summary, a generic key is proposed.
