Distribution of the individual scores for the first two discriminant functions using 13 leaf morphological traits. The initial taxonomic classification of the individual trees (shape and colour of symbols) was based on pubescence characteristics (separation of Q. robur, Q. petraea and Q. pubescens-Q. frainetto), and species descriptions of Flora Europaea (separation of Q. pubescens from Q. frainetto). Nine putative first-generation hybrids and three misassigned individuals (54, 128 and 250) identified using the program STRUCTURE based on 13 genetic markers are shown by black and gray filled forms, respectively.
