PRELIMINARY REPORT ON PEAT.

HydrG'Cotyle sp. Paspalum mucronatum (a grass) 
Scirpus Cubensis Azolla Caroliniana 
Jussiaea leptocarpa Ceratopteris thalictroides (a fern) 
Habenaria repens, an orchid with, inconspicuous greenish 
flowers, is sometimes found in similar places,* but I did not happen 
to see any of it here. Several of these plants are also natives of 
tropical America, and they may associate with the water hyacinth 
in its native haunts. They have all probably, been in this country 
longer than the water hyacinth has, though. 
Although one can travel for several days in Florida without 
seeing any water hyacinth, it is found in some very isolated and 
unexpected places. The peat sample from a shallow depression 
in Choocochattee Prairie, Hernando Co. (No. 20.11), a locality 
several miles from any river or permanent lake, was composed 
mostly of this plant.
