FIGURE 1 in Revision of the Calceolaria tripartita s. l. species complex (Calceolariaceae) using multivariate analyses of morphological characters

FIGURE 1. Bivariate scatter plot formed by the two first components of the Principal Component Analysis (PCA) of 14 characters (A) and 9 floral characters (B) from 190 specimens representing all taxa included in the Calceolaria tripartita complex and C. aquatica. Each point represents one specimen; filled symbols indicate specimens with only one anther theca fertile, empty symbols indicate specimens with both thecae fertile. Ellipses indicate species hypothesis. The different stamen morphologies found in each group are also shown in B.
