Fig. 3 in What pollinators see does not match what they smell: Absence of color-fragrance association in the deceptive orchid Ionopsis utricularioides

Fig. 3. Floral scent profiles of 25 individual flowers of I. utricularioides plotted in two dimensions based on non-metric multidimensional scaling (NMDS; 2D, stress: 0.16). Point colors were superimposed a posteriori on data points according to a scaling based on the continuous color saturation variation in I. utricularioides. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
