PRELIMINARY REPORT ON PEAT. 
329 
Triadenum petiolatum (Walt) Britton 
On rotten logs, etc., in gum swamp about two miles south of Tallahassee. 
Also in the slough west of Lake Iamonia. 
New Jersey to Florida, Missouri and Louisiana, almost confined to the 
coastal plain. 
Hypericum fasciculatum Lam. (Plate 22.1) 
Common around small or medium-sized ponds, lakes, bays, prairies, etc., and 
in the treeless portions of estuarine swamps. Extends south to Palm Beach 
County, but is rare south of latitude 28°. Usually in damp sand, but some¬ 
times on a few feet of peat. 
The form in the estuaries of West Florida has larger leaves than the 
average, and may be H. galioides Lam. In low pine lands and low scrub in the 
lake region is the other extreme, a plant smaller in every way, which is probably 
H. aspalathoides Willd. But there seems to be a perfect gradation between the 
two extremes, and I have never been able to separate the three forms satis¬ 
factorily. 
Typical H. fasciculatum is supposed to range from North Carolina to Texas, 
in the coastal plain. 
Crookea microsepala (T.&G.) Small. (Ascyrum. T. & G.; Hypericum, Gray.) 
Common in and around bays and in low pine land, in Middle Florida, from 
Gadsden County to Lafayette, but chiefly in the flatwoods region. 
Confined to Middle Florida, or nearly so. 
VITACEAE. Grape Family. 
Parthenocissus quinquefolia (L.) Planch. Virginia Creeper. 
Mostly in hammocks, but also in rather dense swamps, whose vegetation is 
approaching the stage in which one may begin to class it as low hammock. 
Widely distributed over the State, growing on peat in Santa Rosa, Franklin, 
Levy, Hillsborough, DeSoto and other counties. 
Widely distributed in Eastern North America. Said to occur also in the 
Bahamas and Cuba. 
Ampelopsis arborea (L.) Rusby ( Cissus stans Pers.; Vitis bipinnata T. & G.) 
Mostly in calcareous swamps and rich soil; not common. Grows on more 
or less peat near Panasoffkee and Tarpon Springs. 
Virgina to Cuba, Illinois and Mexico, mostly in the coastal plain. 
Vitis rotundifolia Mx. Muscadine. Bullace. 
In hammocks and mature swamps, like Parthenocissus. Frequent in clumps 
of small trees in peat prairies. Common from DeSoto County northward; 
noticed on peat in Santa Rosa, Bradford, Lake, Polk and DeSoto Counties. 
Widely distributed in the Southeastern United States.
