FIGURE 5 in Morpho-colorimetric characterization of the perigonium of the Alstroemeria pulchra complex (Alstroemeriaceae, Alstroemerieae) as an aid to delimit its infraspecific taxa

FIGURE 5. Morpho-colorimetric variability expressed through the PC or PCO obtained in each approximation. A: CIELab colorimetry of tepals UL; vectors: influence of the variables on the PCs; B: Reflectance of tepals A; C: Color proportions of tepals I represented as histograms above the scatter plot; D: Maculae patterns of tepals I represented as heatmaps on the scatter plot. Figures in scatter plots: light color circles: A. pulchra var. pulchra; purple circles: A. pulchra var. maxima; darker squares: A. pulchra subsp. lavandulacea. Boxplots: group variability on the PCs or PCOs; box: range 25%–75%; whiskers: min-max; center line: mean; black dots: outliers.
