238 FLORIDA GEOLOGICAL SURVEY—THIRD ANNUAL REPORT. 
CHOCTAWHATCHEE RIVER. 
Although the Choctawhatchee River, unlike the Apalachicola, 
rises in the coastal plain, its head-waters are in the red clay hills 
of the Eocene region of Alabama, and it seems to be always more 
or less muddy, though naturally considerably less so than the 
Apalachicola. 
On Sept. 22, 1910, I went in a launch from the head of Choc¬ 
tawhatchee Bay about twelve miles up the river, and for about half 
this distance the swamps seemed to be essentially estuarine, and 
not very different from those of the Apalachicola at correspond¬ 
ing distances from its mouth. The following plants were noted at 
least twice in the first half dozen miles or so. 
TREES 
Taxodium distichum (cypress) 
Magnolia glauca (bay) 
Nyssa Ogeche (tupelo gum) 
Acer rubrum (maple) 
SHRUBS 
Cyvilla racemiflora (tyty) 
Alnus rugosa (alder) 
Amorpha fruticosa 
Liquidambar Styraciflua (sweet 
gum) 
Nyssa biflora (black gum) 
Juniperus Virginiana (cedar) 
Sabal glabra (palmetto) 
Myrica cerifera (myrtle) 
HERBS 
Scirpus validus (bulrush) 
Phragmites communis (reed grass) 
Cladium effusum (saw-grass) 
Tillandsia usne'cides (Spanish 
moss) (on trees) 
Most of the herbs are confined to strips of marsh a few feet 
wide bordering the water. The peat was not invest'gated, but it is 
doubtless very impure. 
Pontederia cordata (wampee) 
Zizania aquatica (wild rice) 
Dryopteris Thelypteris (a fern) 
Nymphaea fluviatilis (bonnets)
