Abstract

The study of oak diversity in the Southern Iberian Peninsula resulted in the nomenclatural revision of following nothotaxa: Quercus ×beturica (F.M. Vázquez, Coombes, Rodr.- Coombes, Ramos & Doncel) F.M. Vázquez, C. Villaviçosa, C. Meireles & C. Pinto-Gomes stat. nov.; Q. ×numantina Ceb. & C. Vicioso nothosubsp. discreta F.M. Vázquez nom. nov., and Q. ×tentudaica (F.M. Vázquez) F.M. Vázquez stat. nov. Also, three new nothospecies are described: Q. ×ordenensis F.M. Vázquez, García Alonso & Márquez nothosp. nov. (sterile and rare shrub), Q. ×alentejana Pinto-Gomes & F.M. Vázquez nothosp. nov. (fertile and frequent Lusitanian tree), and Q. ×pastorae M.A. Pineda, F.M. Vázquez & Sánchez Gullón nothsp. nov. (fertile and rare tree).
