any Idea of the width of the swamps, there being no hills back 

 of them. 



No abrupt changes in vegetation or environmental conditions 

 were noticed on this trip, but in order to bring out certain con- 

 trasts between the vegetation near the mouth of the river and 

 that farther up I have divided my notes arbitrarily into two parts, 

 selecting as the dividing point Owl Creek, which forms part of 

 the boundary between Franklin and Liberty Counties, about 

 thirty miles from Apalachicola by water. 



In the following table the plants seen below Owl Creek and 

 those seen above it are arranged in parallel columns, as was done 

 with those of the Cretaceous and Eocene portions of the Warrior 

 and Tombigbee Rivers last year.* The number prefixed to the 

 name of each species indicates the number of times it was seen 

 on that section of the river; those seen only once being omitted. 



The country along the lower Apalachicola is so thinly settled 

 that the effects of civilization on the river-bank vegetation, ex- 

 cept for the removal of a good deal of Taxodium distichum by 

 lumbermen, do not need to concern us at present. Almost the 

 only works of man visible from a boat on this part of the river 

 are lumber camps and a few apiaries, the latter being located 

 there to take advantage of the abundance of honey furnished 

 in spring by the two species of Nyssa listed below. f 



The plants noted in the manner above described are as follows :

t See Sargent, Silva N. A. 14: loi. 1902. Calhoun County, which forms the 

 western bank of the river along the greater part of the route here described, is the 

 banner honey county of Florida, producing annually about one-third of the crop 

 of the whole state. 



t Some of the willows seen in the first few miles may be another species which 

 is widely distributed in Florida and passes at present for 5. longipes.
