| FIG. C1. The relationship of the thickness of the leaf lamina with that of adaxial cuticle (A); upper and lower epidermis (B, C); palisade, spongy and total mesophyll (D, E, F). Only A. glabra and C. longifolium had hypodermis (35.0 µm ± 5.30 SE and 29.8 µm ± 2.12 SE thick, respectively). Open and filled circles indicate sun- and shade-establishing species respectively; species symbols are first letters of genus and species. Thickness of abaxial epidermis = 0.0215 lamina + 5.63; thickness of spongy mesophyll = 0.721 lamina - 47.4; thickness of mesophyll = 0.793 lamina + 7.23. |
