I spoke above of the antagonism of these two floras. This is 
so marked that there is no mistaking it. Wherever they come to- 
gether the line of division is very distinct. A bare space of pure | 
white sand usually separates the two. On one side you will see 
the tall Pinus palustris as far as the eye can reach, and on the 
other the diffusely branched P. clausa of much lower stature. 
You may look in vain in the “scrub” for plants occuring in abun- 
dance just over the line in the high pine land, and vice versa. 
The strip of bare white sand dividing the two is neutral ground, 
and each seems to jealously guard against the other's gaining a 
foothold there. The soil of these two sections was apparently 
originally the same pure white sand. That in the high pine land 
is now darker in color, being probably due to the charcoal de- 
posited there by the annual fires. This seems to be the only dif- 
ference. As fires are of rare occurrence in the “scrub,” the 
plants have made no provision against it, and so when a fire does go 
through it causes great havoc, almost entirely killing the pines 
and oaks. It is fortunate that fires are of such rare occurrence. 
The flora of the low pine land region is not so distinct. It 
grades into that of the high pine land. Each has its separate and 
peculiar plants, but the line of demarcation is not so evident. 
Pinus serotina and P. heterophylla are the prevailing trees. Some 
of the plants which are peculiar to and characteristic of this region 
re: ° Podostigma pedicellata, Trilisa odoratissima, Solidago Chap- 
mant, Bejaria racemosa, Cracca hispidula and C. spicata, Eryngium 
yuccaefolium synchaetum, Rhexia ciliosa and R. serrulata, Bletia 
verecunda, Limodorum parviflorum and Juncus marginatus pine- 
torum. The commonest member of the Cyperaceae is Fimbristylis 
puberula, which occurs in great abundance throughout the low 
pine land. Aristida stricta also occurs here, as well as in the high 
pine land. Andropogon Floridanus is quite common and.a very 
showy member of that genus. = 
The low pine land occupies an intermediate position between 
the high pine land and the flatwoods. The latter is not repre- 
sented near Eustis, and so I did not get a chance to do any col- 
lecting among that flora, which differs in a marked degree from 
that of any other section. 
The large swamps, lying generally along the low pine land,
