Figure 30. Three shoreline dominants, sweet bay (B), red cedar (C), and cabbage palm 

 (P), are characteristic of the tidal zone of an alkaline blackwater river (St. Marks, 

 FL). An intertidal zone (T) can be seen between the root zone (H) at the high tide 

 line (partly in shade) and the dark water (W), which has a band of submerged plants 

 (S), here partly exposed.
