On the nomenclature of fossil Aspleniopteris, Carpinicarpus, Comptonia, Comptoniphyllum and Dryandrophyllum (Myricaceae)

Abstract

AbstractComptonia comptoniifolia(Brongn.) Doweld, comb. nov., based on the recently rediscoveredPhyllites comptoniifoliusBrongn., is reinstated based upon priority as the earliest validly published species name in place of the previously incorrectly usedC. acutilobaBrongn. andC. difformis(Sternb.) E.W. Berry (Aspleniopteris difformisSternb.;Asplenium difformeSternb. non R. Br.).Comptonia japonicaKrysht. is shown to be the earliest validly published name instead of the previously widely acceptedComptoniphyllum naumanniiNath. A new genus,Paracomptoniagen. nov., is proposed instead of the previously invalidly publishedDryandrophyllumVelen., being based on the formerly segregatedComptoniasubg.AvushiaZhilin, with transference of two CretaceousDryandraspecies,D. cretacea, andD. yakovlevii, and one Palaeogene species,D. schrankii, intoParacomptonia. The aberrant fossil species of Western SiberianComptonia, based on fruit endocarps with a superficial resemblance to the extant genus, are reclassified and transferred into the recircumscribed and amplified distinct fossil genusCarpinicarpus, which is reinstated as a validly published genus instead of the anomalousComptoniasection †ComptoniellaP.I.
