PRELIMINARY REPORT. ON PEAT.

Taxodium imbricarium (Nutt.) Harper. (Pond) Cypress.
(PLATES 22.2, 23, 27.2, 28. FIG. 24.)
Abundant in cypress, ponds, bays, non-alluvial swamps,, etc., in all the counties north of latitude 290, with the possible exception of Marion. Farther south it is more scattered, being quite uncommon in the lake region. It is abundant, however, in Pasco and Hillsborough Counties, and the northern parts of Osceola and Brevard, and I have seen it in a few places in Lake, Orange, Palm Beach and Dade. It grows on deep but impure peat in the estuarine swamps of Santa Rosa County.
North Carolina to Louisiana, in the coastal plain.
Pinus Elliottii Engelm. Slash Pine.
(PLATES 22.1, 23.1, 28. FIG. 20.)
Very common in bays in Middle Florida and in cypress ponds in East Florida, and in various kinds of non-alluvial swamps, sphagnous bogs, and wet pine lands, as far south as DeSoto County. Not abundant in West Florida. Never in permanent water. Grows on several feet of peat in the estuaries of Santa Rosa County and the slash-pine bogs of Lake, Polk and Hillsborough, but elsewhere usually in sand.
South Carolina to Mississippi, in the coastal plain.
Pinus serotina Mx. Black Pine.
In sour sandy swamps, bays, etc., from Walton County on the west to the northern parts of Brevard and Osceola on the south; avoiding distinctly calcareous regions like the*West Florida limestone region, the lime-sink or phosphate region, and the Gulf hammock region. Grows on several feet of peat in the landward part of the river swamp near Palatka, and in shallow peat in many of the Middle Florida bays, but elsewhere usually in sand. Although it has no use for limestone, it is often found pretty close to places where there seems to be marl near the surface, especially in the northern edge of the South Florida flatwoods, and near the St. Johns River. Perhaps the reason for this is to be sought in some peculiarity of the water supply in such places.
Extends northeastward to Virginia in the coastal plain, and has recently been found in southern New Jersey.
