Morphological diversity of leaves across different scales. (A) Morphology of C. hirsuta (Ox) and A. thaliana (Col-0) rosette leaves; different parts of the leaf are indicated. (B, Upper) Silhouettes of the fifth rosette leaf illustrate diversity in leaf morphology of natural C. hirsuta strains. (B, Lower) Quantification of total leaflet number in the first eight rosette leaves is shown in the bar chart. Data are reported as means ± SD. (C) Silhouettes of the first nine rosette leaves from a typical heteroblastic series in C. hirsuta (Ox).
