Medifibrists and Medisaprists formed over mineral parent materials. Psammaquents and Ochraqualfs have developed where limestone rocks are at greater depths. Along the coasts are Sulfihemists and Sulfaquents. Soils in this Section have a hyperthermic temperature regime and are mostly aquic in moisture regime. Most soils inland from the coasts are poorly drained, shallow, and moderately textured.
Some coastal soils are deep sands that are well drained or excessively drained.
Potential Natural Vegetation. Physiognomy of vegetation varies by duration of inundation and amount of salt content. Epiphytes are common. Poorly drained soils along the east coast, and farther inland along the west coast, are dominated by south Florida slash pine. Sand pine, with scrub oak and saw palmetto understory, occupies excessively drained, deep sands.
