PRELIMINARY REPORT ON PEAT. CAPRIFOLIACEAE. Honeysuckle Family. Viburnum obovatum Walt. Usually in river and creek swamps where either the water or soil is calcareous, and there is very little peat. Extends southward to DeSoto County, westward to the Apalachicola River, and northeastward in the coastal plain to North Carolina and perhaps Virginia. Viburnum nudum L. Possum Haw. In non-alluvial or non-calcareous swamps. Escambia, Santa Rosa (estuaries), Walton, Hillsborough, Polk and DeSoto Counties, and doubtless at many intervening points. Long Island to Louisiana, mostly in the coastal plain. Sambucus Canadensis L. Elder. In rich damp soil of various kinds, sometimes in drained marshes, etc., like Erechthites, but often apparently indigenous. Probably grows in every county in Florida. In South Florida it becomes a small evergreen tree, and blooms every month in the year, or nearly so. Nearly throughout temperate North America east of the Rocky Mountains, but natural range and habitat uncertain. RUBIACEAE. Madder Family. Cephalanthus occidentalis L. Elbow-bush. Buttonwood. Button-willow. Button-bush. Globe-flower. Common throughout the State, in fresh-water swamps and ponds of various kinds, where the water fluctuates a foot or more with the seasons, leaving the soil exposed a good deal of the time. It therefore avoids the sour non-alluvial swamps and bays, and prefers mucky or muddy places. Nearly throughout the Eastern United States, and in the West Indies. Diodia Virginiana L. In a shallow peat prairie near Rochelle, Alachua Co. Not rare in damp places of various kinds, often as a weed. New Jersey to Texas, mostly in the coastal plain. BIGNONIACEAE. Cross-vine Family. Crescentia cucurbitina L. Calabash Tree In a mangrove swamp near Lemon City, Dade Co. Also in low hammocks in the same general region. South Florida to Venezuela. LENTIBULARIACEAE. Bladderwort Family. Utricularia. Most of these are not in condition for identification in wimer and spring, when the peat deposits of Florida are most conveniently examined. They commonly float in permanent stagnant coffee-colored water, in places where they 319
