PRELIMINARY REPORT ON PEAT.

Andropogon sp. (perhaps several of them). Broom-sedge.
Common in dryish peat prairies, etc., in Duval, Putnam, Alachua, Lake, Orange, Osceola, Polk and DeSoto Counties. (Most of them bloom in the fall, so that I have not been able to identify them).
Erianthus sp.. (perhaps two or three. These, too, bloom in the fall).
In saw-grass marshes, slash-pine bogs, cypress ponds, etc.; not common. Jackson, Leon, Duval, Lake, Orange and Polk Counties.
HYDRO CHARITACEAE. Frog's-bit Family.
Limnobium Spongia (Bosc.) L. C. Rich.
In calcareous streams in Jefferson County, and in pools in a non-alluvial swamp about two miles south of Leesburg. Doubtless in many other places, mostly in permanent water.
Ontario to Florida and Louisiana, mostly near the coast.
Vallisneria spiralis L. Eel-grass.
All submerged but the pistillate flowers, in the St. Johns River near Palatka (and doubtless many other places), and in Lakes Harris and Apopka. Doubtless grows on the outer edge of many peat deposits that are advancing into large lakes and estuaries.
Widely distributed in temperate regions where there are large bodies of still fresh (or even slightly brackish) water, as in our glaciated region and coastal plain.
ALISMACEAE. Water-plantain Family. Sagittaria latifolia Willd. Arrowhead.
In wet muddy or marly places; not common in Florida. Escambia, Leon, Madison, Lake (Helena Run) and Dade (head of Miami River) Counties.
Widely distributed in temperate North America.
Sagittaria lancifolia L. Wampee?
Very characteristic of saw -grass marshes, lake margins, wet prairies, and various other kinds of exposed wet places, especially where there is limestone in the water or near the surface. Widely distributed over the State, perhaps in every county which has considerable areas below the Ioo-foot contour.
Delaware to Central America, usually within 50 miles of the coast.
Sagittaria natans Mx.
Chiefly in calcareous springs and streams; all submerged but the flowers. Jackson, Wakulla and Citrus Counties. Lee County (Hitchcock).
South Carolina to Alabama, in the coastal plain.
