(For a de- scription and another view of the same place, taken a year or two later, see J. F. Kemp, Econ. Geol. 14:311, pi. 5 b. 1919.) Vegetation. The flatwoods of the east coast differ from those previously described in having more slash pine than long-leaf. The old dunes (fig. 31 ) are generally covered with spruce pine and other scrub vegetation much like that of the lake region, passing into sandy hammocks where sufficiently protected from fire by the prox- imity of water-courses, etc. In marly places there are large areas of low hammock (fig. 29), passing into swamps where traversed by streams. The dunes near the ocean have vast thickets of saw- palmetto (fig. 33). Less extensive types are the palm savannas on Merritt's Island (fig. t,2). and a little salt marsh and mangrove sw^amp. The shell mounds are commonly covered with dense ham- mocks of a decidedly tropical character. The commonest plants are listed below, but on account of the indefiniteness of the inland boundary of the region in some places the sequence cannot be guaranteed as Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Florida Geological Survey.
