Figure 18. 1-6. Fossil and extant Strasburgeria (Strasburgeriaceae). 1. CUT-Z-FFH, TLM view showing two stomatal complexes (SL3224, scale-bar = 50 µm); 2. CUT-Z-FFH, TLM detail of single stomatal complex (SL3224, scale-bar = 20 µm); 3. CUT-Z-FFH, SEM view of inner cuticular surface showing two stomatal complexes (S-1362, scale-bar = 20 µm); 4. CUT-Z-FFH, SEM view of outer cuticular surface showing a single stomatal complex with prominent outer stomatal ledges (S-1362, scale-bar = 10 µm); 5. Extant Strasburgeria robusta, TLM view showing a group of networked stomatal complexes (AQ391571, scale-bar = 50 µm). The details are partially hindered by cutinisation around the internal walls of the epidermal cells; 6. Extant S. robusta, TLM view showing a single stomate (AQ391571, scale-bar = 20 µm).
