FIGURE 1. A. Principal Component Analysis of 14 variables. Projection of 81 samples on PC1 (27%) and PC2 (13%). Squares: Monotes caloneurus, circles: M. elegans, crosses: M. schmitzii, diamonds: M. hypoleucus. Apsin = depth of apical sinus, basin = depth of basal sinus, Dfr = fruit diameter, LL = Leaf length, Lw = leaf width, L/w = length/width ratio, lowcol = colour of lower surface of leaf, lowhair = density of hairs on lower surface, Lpet = petiole length, Lwings = length of calyx wings at fruiting stage, nerves = number of lateral nerves on one side of the midrib, shap = distance from base to largest width relative to leaf length, upcol = color of upper surface of leaf, uphair = density of hairs on upper leaf surface. B. Non metric multidimensional scaling, based on 14 variables. Projection of 81 samples on the first two axes. Squares: Monotes caloneurus, circles: M. elegans, crosses: M. schmitzii, diamonds: M. hypoleucus. See Appendix for the list of specimens included.
