246 FLORIDA GEOLOGICAL SURVEY-THIRD ANNUAL REPORT.
SWAMP WATER AND NON-CALCAREOUS SOIL.
ALLUVIAL SWAMPS.
The alluvial swamps of coffee-colored streams differ from those of muddy rivers in being sandy instead of muddy (so that one can walk about in them with little discomfort when the water is low), but resemble them in containing little or no peat, and to a considerable extent in the character of the vegetation.
The following species have been observed between high and low water marks along the Ocklocknee River in Leon County, the Fenholloway near Hampton Springs, the Suwannee near Branford, and Peace Creek or River near Arcadia.
