Figure 10.8–Epidermis (A-E) and cuticular epithelium (F-I) of Arceuthobium tsugense (A-D, F, H-I) and A. globosum (E-G) stems as seen in transverse (A-G) and longitudinal (H-I) sections. A: cuticular layer (cl) of intermediate thickness, x250. B-D: thick cuticular layer as seen using brightfield, fluorescence, and polarization optics, note cuticular pegs (p) between adjacent cells, x400. E: individual epidermal cells becoming isolated (at arrows), x250. F: cuticular layer formed by subepidermal cells, x100. G: thick cuticular epithelium (ce), x100. H-I: crushed stomata showing subsidiary (s) and guard (g) cells, note small substomatal chambers, x250.
