Fig. 10.2-4. Transverse section of leaf of bearberry (also called kinnikinnick; Arctostaphylos uva-ursi). The cuticle here is so thick it hides the shape of the cells below. The cuticle has an outer layer that is dark pink: that is probably pure cutin, forming the cuticle proper. Closer to the cell lumen, the cuticle has a whitish hue, that is probably the cutinized outer wall of the epidermis cells, a mixture of cell wall material and cutin. This is a plant of the Pacific Northwest of the United States and Canada, exposed to very high rainfalls.
