Validating subfamily, genus and species names in Loasaceae (Cornales)

Abstract

AbstractThe new generic names Nasa, Xylopodia, Aosa, Presliophytum and Chichicaste, the subfamily name Petalonychoideae (all in Cornales, Loasaceae), the new species Blumenbachia exalata, Nasa cuatrecasasii, N. orbicularis, N. pilovena, N. profundiserrata, N. rufipila and Presliophytum arequipensis and the new combinations Aosa gilgiana, A. parviflora, A. plumierii, A. rostrata, A. rupestris, A. uleana, Chichicaste grandis, Nasa rubrastra, Presliophytum incanum and P. heucheraefolium are validly published. These names appeared in a PhD thesis submitted to the Ludwig–Maximilians Universität München, Germany, in 1997. Being printed and distributed to over 60 libraries, this thesis met the formal requirements for effective publication of the International Code of Botanical Nomenclature then in force, but is no longer effectively published as a result of a retroactive change in the rules adopted at the International Botanical Congress in Vienna in 2005. As a result, the new names appearing in the thesis were not validly published and the nomenclatural novelties ineffective. The new names published in this thesis are validated here since they have found widespread use in numerous publications; moreover, the new generic delimitations have been confirmed by molecular studies. New species and combinations described in the genera concerned in publications other than the thesis will be validly published elsewhere.
