CAPRI FO LI ACE AE. Honeysuckle Family. 
Viburnum obovatum Walt. 
Usually in river and creek swamps where either the water or soil is calca¬ 
reous, 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 (estua¬ 
ries), 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 Erechthitcs, 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 win.er and spring, 
when the peat deposits of Florida are most conveniently examined. They com¬ 
monly float in permanent stagnant coffee-colored water, in places where they,
