Fig. 3From: Using joint multivariate analyses of leaf morphology and molecular-genetic markers for taxon identification in three hybridizing European white oak species (Quercus spp.)Species composition of the 71 investigated populations of Quercus in Switzerland using factor analysis of mixed data (FAMD) and subsequent hierarchical clustering of principal components (HCPC). Species assignment of the clusters was done according to hair types (Fig. 1). Pet = Q. petraea, Pub = Q. pubescens, Rob = Q. robur Back to article page
