Figure 7
Leaf shape variation in C. cujete varieties. A) PCA of elliptic Fourier coefficients of leaves from trees growing in wild (black symbols) and homegarden (white symbols) sites. Each point represents the mean leaf shape of one tree, based on 10 leaves. B) Graphical representation of leaf shape variation through PC1 (top) and PC2 (bottom). The first three leaves represent (from left to right) mean leaf shape less one standard deviation, mean leaf shape, mean leaf shape plus one standard deviation; all three are superimposed in the rightmost figure.
