FIGURE 4 in Variability of leaf blade anatomical traits in the Sesleria juncifolia complex (Poaceae) on the Balkan Peninsula

FIGURE 4. Principal Component Analysis (PCA) based on leaf blade anatomical characters of populations of Sesleria juncifolia complex labeled with population acronym shown in Table 1. Color coding (different shades of blue, red and green) of populations reflects the groups (three species) tested in canonical discriminant analysis. Green—populations of S. juncifolia, blue—populations of S. interrupta, red—populations of S. ujhelyii.
