Proposal (30) to conserve the name Polysticho setiferi-Fraxinetum excelsioris (Tüxen et Oberdorfer 1958) Rivas-Martínez ex Díaz et Fernández Prieto 1994 with a conserved type

Abstract

Abstract: The association Polysticho setiferi-Fraxinetum excelsioris was described as a meso-eutrophic thermophilic forest dominated by common oak (Quercus robur) with a distribution that includes the Oviedo district in Asturias and the Basque-Cantabrian area (N Spain and SW France). However, when a lectotype was chosen to comply with Article 19 of the ICPN, a relevé dominated by beech was selected, which leads to interpretive problems. Given that the most widespread interpretation of this association in the phytosociological literature is the one established by its original authors (i.e., a meso-eutrophic oak-ash forest), we consider that this name should be retained, but its type should be changed to a conserved neotypus according to Article 53 of the 4th edition of the ICPN.
