At the very limit of high water are sometimes found Pinus Caribaea or small saplings of Pinus palustris (long-leaf pine), a few shrubs, such as Pieris nitida, Serenoa (saw-palmetto), Ilex glabra (gallberry), Vaccinium sp. (huckleberry) and Cyrilla sp. (tyty), and one or more of the following herbs: Spartina Bakeri,, Aristida spiciformis, Junicus scirpoides compositus, and Rhynchospora fusca. Often this sort of vegetation makes a belt of low scrub a good many yards in width, in which Pinus Caribaea, Serenoa, Pieris nitida, Ilex glabra and Aristida spiciformis are the prevailing plants. But where the shores are comparatively steep there is usually a well-marked fringe of saw-palmetto just above high-water mark (see plate 24.1), and immediately back of it the characteristic high pine land with long-leaf pine, turkey oaks, wire-grass, etc.
The plants of the various zones above described all tend to migrate toward the center of the lake as the peat accumulates, and when the lake is completely filled, and thus converted into a peat prairie (which will be described later), some of the same species which grew on sandy shores are found well out toward the middle, on several feet of peat.
The peat around small lakes which are not completely filled is usually too shallow to be of much importance, but it is of pretty gobd quality, being almost free from mineral matter and woody roots and stems. Analyses of this kind of peat will be found in the table under localities 12, 13 and 22.
