250 FLORIDA GEOLOGICAL SURVEY-THIRD ANNUAL REPORT.

HERBS
Coreopsis angustifolia Cladium effusum (saw-grass) Typha latifolia (cat-tail) Oxypolis filiformis Pontederia cordata (wampee) Juncus Roemerianus (rush) Fuirena scirpoidea Panicum virgatumn (a grass) Boltonia diffusa Castalia odorata (white water-lily) Mesadenia sulcata Eryngium virgatum Rhynchospora corniculata

Lophiola aurea Zizania aquatica (wild rice) Cyperus virens Eriocaul6n sp. Phragmites ccmmunis (reed grass) Cyperus Haspan. Sagittaria lancifolia Ludwigia alata Iris versicolor (blue flag) Juncus polycephalus (rush) Polygala cymosa Nymphaea fluviatilis (bonnets) Myriophyllum sf.

Just about half the species noted in each of the two swamps (which are only 12 miles apart in a straight line) were common to both.
Right at the mouths of these rivers the marshes with shrubs and herbs are more extensive than the wooded swamps, but in going up stream one would doubtless soon find the proportions reversed.
The peat is several feet deep in the Escambia estuaries (its depth was not investigated at the mouth of the Yellow River), but probably still more impure than in the case of the Blackwater, and therefore of little value.
EAST FLORIDA.
The only fresh-water estuary in East Florida, besides the St. Marys River (which I have not examined on the Florida side) and a few creeks south of it, is that of the St. Johns River. The tides ascend this remarkable stream about to Lake George, giving it something like Ioo miles of estuary. The following plants which I have seen in the river swamps between Palatka and the railroad bridge about five miles south of there are probably fairly typical of this whole lower portion of the St. Johns.
