PRELIMINARY REPORT ON PEAT.

Hydrocotyle 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.
