This list of plants has a good deal in common with that of the 
Apalachicola estuaries, although the two places differ greatly in the 
chemical composition of their soil and water. I did not make any 
examination of the peat, but I would not expect it to be very 
deep, and the parts that are full of trees will doubtless escape 
utilization for a long time to come. 
ESTUARIES OF DADE COUNTY. 
On the east side of Dade County there are quite a number of 
short rivers running from the Everglades to the coast, which, like 
the Suwannee River, seem to be coffee-colored all or nearly all the 
time, but must carry some calcium carbonate in solution, too. 
Also like the Suwannee, they have cut channels in limestone rock, 
and are of the nature of estuaries for a few miles from their 
mouths. These are of interest as being almost the southernmost 
estuaries in the United States, and having a somewhat tropical 
vegetation. They have not been examined very carefully. Most 
of the plants in the following list were noted in going up New River 
from Fort Lauderdale to the Everglades on April 12, 1909, and 
the remainder on the Miami River about two miles from its mouth 
a few days earlier.
