Introduction

Amongst European quercophiles probably one of the most debated topics is the incredible morphological diversity of Quercus pubescens (downy oak) and whether these different morphotypes should be considered one species or not. The many names that have been created by different authors throughout time and in different countries is proof that this is not an easy question.
