FIGURE 1. Biplot of principal component analysis (PCA) of S. meeboldii (red), S. pulvinaria (green), S. ×klimesii (black) and artificial hybrid (blue); cultivated plants are represented by dot, plants from herbaria by triangle. A. PCA of all analysed plants of both cultivated and herbaria origin showing variation in length (Rudel) and width (Rusir) of leaves and number of pores (Pporu) of leaves. Ordination axis 1 explains 42.71 % and ordination axis 2 explains 22.24 % of variance of the sample set. B. PCA of all 10 analysed morphological traits based on cultivated plants only. Ordination axis 1 explains 57.11 % and ordination axis 2 explains 28.81 % of variance of the sample set. Pporu—number of pores, brvy—presence of cilia, Kdel—length of calyx, Ksir—width of calyx, Cdel—length of corolla, Csir—width of corolla, Adel—length of anther, Asir—width of anther.
