SThe general trend of the peninsula as we all know, is nearly '
southward. The highest lands occur west of a line drawn down t .
middle of the peninsula. This is the primary axis of the peninsula."-
elevation of this region varies from about sea level to rarely
thm two hundred feet.
Sl:at the primary axis running parallel to it is a secondary
lting i dth up to about forty miles. Lying between these -
axes IS tls^e4. Jobfa River and a series of lakes terminating in
S.t t he northern border of tSevergladea. e St. Johnsa
river is really only a series of fresh water lakes connected by wide
Streams. The oerwe of the St. Johns Kivers is only about twenty
S feet above sea level and as it is .over e00 miles long reas:ured by
its tortuous route to*the ocean, we see that there is no chance for -
rapid flowing streams.
Along the east coast is a series of salt rater lagoons usually
spoken of as rivers. owards the east of these lagoons are narrow
islands which rise only a few feet above sea level. On these aas "

well adapted to a xerophlytic existence. In brief the scrub may oe
described as an inland or an extinct sand adne. The species peculiar
to the scrub are rinus Clouea, Quercus Myrtifolia, ceratiola ericoidea

GENERAL OON OKHMATION.
The northern tier of counties beginning with Baker, about for-W
miles west of Jacksonville to Pensacola partake so much of the nature
of the adjoining states to the north, this portion may be called
Northern Florida and is not considered in this discussion.
The general trend of the peninsula as we all know, is nearly
southward. The highest lands accur west of a line drawn down the
middle of tne peninsula. This is the primary axis of the peninsula.
The elevation of this- region varies from about sea level to rarely
more thtn two hundred feet.
East of the primary axis aid running parallel to it is a secondary
axis, varying in width up to about forty miles. Lying between these
axs6 is the St. Jons. River and a series of Lakes terminating in
Okeechohee, at the northern border of the everglades: the st. Johns
river-is- really only a series of fresh water lakes connected by wide
streams. The source of the St. eJhns River is only about twenty
feet above sea level and as it is over 200 miles long measured by its
tortuous route to the ocean, we see that there is no chance for rapid
Along the east coast is a series of salt water lagoons usually

islands which rise only a few feet above sea level. On these s W
Peninsular ilorida stretches about 400 miles from north to south
and is about 130 miles broad at its widest.

extreme cases may reacn 15 degrees F. It rarely rises above 95
degrees k. with the extreme at 101 degrees Throughout the southern
extremity tne temperature rarely goes down to freezing and rarely
above 95 degrees F.
The rainfall for the northern section is rauner uncertain as to
time of occurrence. The average annual amount being about 50 incnes.
For the southern section, the average annual rainfall is about
60 inches occurring mostly during tne summer months. the fall,
winter and spring months are usually dry. For these the average
is about 2 1/2 inches per month.
If we keep the map of Florida in mind we will see that it is a
Mather broad peninsular with no elevations rising above 375 teet.
Consequently, the climate cannot be influenced preceptibly by the
altitude. The state, however, stretches through 5 1/2 degrees of
latitude wnich nas a very perceptible influence on the vegetation.
The southern portion of the state is still further favored by the
presence of the Gulf stream which flows along the banks and strikes
the coast at latitude 27 degrees. The soil is uniformly sandy.

This formation occurasas islands in the extensive piney woods
The areas are very sharply defined as a rule and nearly always of a
circular shape. The exceptions to this rule occurs when the
hammocks border a body of water. The pine trees are doubtless the
first to occur from a historic point of view. This seems to be
borne out strongly by the fact that the portion of the peninsular
that is geographically the oldest, contains the most extensive
hammocks. In the southern portion, on the border of the Everglades
the hammocks are very small rarely more than a few acres in extent;
while in the northern portion they extend for miles.
SPhytologically, the hammock is the richest formation. The
total area amounts to only a small per cent of the tote&, yet
contains more than 80 r cent of the plant species.
The most surprising fact is that the soil of the hammock
is no different from that of the pine woods, yet the effect on the
6 ,native vegetation is most striking.
SThe hammocks are characterized by the presence or broad leaved
trees, shrubs, and vines. Quertus Virgir!iana is one of the dominant
species. in the northern portion of the peninsula i:-few pine trees
occar in them but in the southern portion where the species of
pines are fewer, a pine tree is almost never known to occur in a
hammock. Pinus palustris, I'. Taeda, P. Clousa,and P.,lliottii very
rarely occur in hammock formation while P. Glabra and P. Echinata
rather prefer the hammook,
(2) Hammock (2)
The cabbage palmetto occurs rather commonly in tre nammocks
and in many cases becomes the dominant species and under certain
exceptional conditions may oe almost the exclusive aroorescent
representative as is shown by the four views taken in somewhat
widely separated portions of Florida.
closely allied and very similar to the hammock is the so-called
bay head. The dominant species are the same as in a hoammock but
the undergrowth is very different since the soil for a portion
of the year is under water. The shrubs in this area are various
species of fleex. 6phagaruum moss beds occur frequently/
The features present in the namnock are so radically different
from those present in the pine woods tnat-one cannot be convinced
easily that there is not a difference in soil or supply of
moisture or other physical factor that determines the presence of
the hard wood area. I have triea all along to bring out the fact
that there is a very s-uarp demarkationbetween the two plant
* formations, not only as to the species but also as to the behavior
of species that are able to exist in both formations.
ie have three very strong arguments in favor of our belief
that the soil is not responsible for the change in plant formation
The difference between the chemical analysis of hammock soil and
pine woods soil is no greater than the difference between analyst
of different samples of pine wood soil. The mechanical analyses
likewise gives us no constant difference.
By far the strongest argument that we have in favor of the
belief that there is no essential difference in the original.
Ii Hammocks (3)
constitution of hammock and of pine woods soil is round on the grouns
of the subtropical laboratory. A portion of the area was originally
covered with hammock, another portion with pine woods. Rows of
citrus hybrids and other plants are planted so as to cress from the
pine woods areas to tne hammock area. Yet no difference can be
detected in the vigor or vitality of the plants located on what was
originally very different plant formation. Let me make my meaning
clear at this point. I mean to say that -rigirally there was no
difference in the soil of the nammock formation and the pine woods
formation and that the increased productiveness of the hammock soil
Sis to be credited entirely to tne presence of the hard wood species.
Artificial hammocks are frequently established and they not only are
able to maintain themselves but may become aggressive.
The origin of a hammock as I take it is entirely a matter
accident. In south Floridawhere hammocks are or smallest size,
Quercus Virginiana, is the nucleus, most frequently, about whidh
r elements are assembled. It should net be inferred, however,
t this species is the only one that can start a nammock, but that
it seems especially well adapted for the task in peninsular Mlorida.

The piDy woods po~ds and their studies are sufficiently
interesting to entitle them to a separate paper. In passing, I
.ay say that they form an Important diversion in this vasr sea of
pine woods aomotony. The character of the ponds depent# upeo
naturall conditions. There are various kinds,- grassy, weedy,
Tupelo (JSysa) and cypress with various gradations,
THE PINEY WO0DS.
The striking features of this area is as the name indicates the
pine woods. In the northern section of the state P. palustris is
ia the predominant species. One may drive or ride -nany miles without
seeing a single other species of pine. The long straigth shaftlike
trunk reminds one strongly of the former northern pine forest.
Heirand there occur ponds, lakes and streams. The ponds are occupied
by Toxodium or by NyWta, depending upon the character of the pond.
Along Vhe streams are found hard woods of various species.
Toward the south below latitude 26 1/2 degrees occurs the slash
_pine or Cuban pine, P. Elliottii. The general aspect of this is the
Same as that of its more northern corgenor, P. Palustria. In the
densest of these forests the undergrowth is almost entirely absent.
Throughout the entire peninsular region Serenoa serulata occurs as
one oi the undergrowtns. Pteridium condatum also come in as a p
prominent feature in the Pinus Elliottii forests.
It is difficult to estimate the total area of this formation
but it certainly covers 75 *0e"s of the peninsular if we except the
Everglade region. One rarely meets shrubs that grow more than.30 or
40 inches high and these are usually characteristics of this formation.
Wees where the species attain the size of trees in the hammock
formation they remain stunted shrubs in the piney woods. As illustra-
tion of this peculiar dwarfy effect we have retotium MWtopium,
which makes a tree often $0 or more feet tall in the hammock but
remains a shrub less than three feet tall in the pine wood. in the
latter situation it proauees a large stumplike growth from which
