Fig. 10.2-10. Transverse section of lilac leaf (Syringa). These epidermis cells have an outer wall that bulges outward as a papilla, but they also have a sculptured cuticle. The peaks and spikes on the cuticle are so fine that they are barely visible even at this high magnification. In a section like this, they appear to be just spikes, but if may be that we are seeing cross sections of ridges of cutin we would need SEM or leaf peals to determine that. For example, look at the SEMs of cutin ridges and projections in Figs. 10.14 and 10.16 on page 177 in Plant Anatomy (Mauseth).
