FIGURE 5. Factorial analysis of mixed data (FAMD) of seeds characters and hierarchical clustering on its principal components (HCPC). Distribution of the quantitative variables (a). Distribution of the qualitative variables (b); 2-4rows—number of rows in crest; 1- 2chambers—number of hilum chambers; marginal/middle—hilum location; brown/black—colour of seed; present/lack—waxes in hilum chambers; matt/shiny—surface type. Variation of elevation variable (c). Variation of habitat variable (numbers correspond to NATURA 2000 codes) (d). Five clusters of species identified by Hierarchical Clustering on Principal Components (HCPC) (e). ALP—H. alpestre; MAC—H. macranthum; RET—H. retzdorffianum; NIC—H. nikolicii; OLI—H. oliverae; PUS—H. pusillum subsp. pusillum; ALB—H. pusillum subsp. albanicum; MARK—H. pusillum subsp. markgrafii; MON—H. pusillum subsp. monachorum; CAN—H. pusillum var. candavicum; CHROM—H. pusillum subsp. chromodontum.
