FIGURE 5. Planar representation of the morphospace of shoots, foliage leaves and bracts in flowering plants (after Jeune et al. 2006). The process combinations of watershoot leaves and bracts of the aquatic plant Utricularia foliosa (Lentibulariaceae) are visualized by Principal Components Analysis of the developmental processes shown in Table 1 (see Jeune et al. 2006 for a more detailed explanation). Each point in the morphospace represents an individual plant structure. The process combinations of watershoots (black circle) and leaves (cross) are more similar to each other than either is to the process combination of bracts (black diamond).
