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 27°!$. The various Tillcmdsias, 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.
