This list of plants does not differ very much from that of the lake region swamps just described. The interior of such a swamp is decidedly less tropical in appearance than one might expect in latitude 27015'. The various Tillandsias, and the three ferns which are not known north of Florida, are about the only suggestions of tropical conditions, most of the other plants being just as common four or five hundred miles farther north. Several of the species, such as Nyssa, Gordonia, Pinus Elliottii, Viburnum, Phoradendron and Arisaema, are here just about at their southern limits.
A sample of peat from about a foot below the surface in one of these swamps (locality No. 21) was very coarse, but of pretty good quality otherwise.
