European taxonomists are divided regarding Quercus dalechampii, considering it either: (1) a distinct species close to Q. petraea, (2) a distinct species close to Q. pubescens, or (3) falling within the morphological variability of previously described species, including Q. petraea and Q. pubescens. These taxonomic disagreements are largely due to inconsistencies between the description of Q. dalechampii and much of its original material. In order to resolve these differing interpretations, all available original material was examined and a lectotype, superseding a previous neotype, was chosen from this material. The original material for the name consisted of mixed material belonging both to the Q. petraea complex and the Q. pubescens complex. The lectotype designated here is characterized by pubescent leaves and belongs to the Q. pubescens complex.
