triment, enough to enable it to start up again atonce. The above 
are only a few instances of the many means which insure the 
preservation of the different species. 
The “scrub” flora is entirely different from that of the high 
pine land, hardly a single plant being common to both; in fact 
these two floras are natural enemies and appear to be constantly 
fighting each other. The only large tree growing in this region 
is Pinus clausa, which is markedly different from P. palustris, the 
pine of the high pine land. The latter is a tall, straight tree, 
with the branches restricted entirely to the top. P. causa, oh the 
contrary, is branched almost from the very base and does not at- 
tain a height of over 30 feet. Its needles are very fine, and it has 
received the name of the “spruce pine.” The great part of the 
growth in the “ scrub” is made up of scrub oaks, which are so var- 
iable that no two of them seem to be alike, and how many species 
there may be would be hard to tell. | Only a number of years of 
close study in the field could determine this. Cevatiola, with its 
heath-like leaves, occurs here very abundantly. Persea humilis, a 
most beautiful little shrub, makes itself very conspicuous by its 
bright brown silky pubescence, which is noticeable a long way off. 
Bumelia lanuginosa is very common, as is Ximenia Americana. 
Smilax Beyrichii climbs all over the scrub oaks, and is the only 
one of this genus observed growing in the “scrub.” One of the 
most beautiful plants of this part of Florida is Breweria grandt- 
flora, with its large, bright blue flowers. The stems, with their 
_ peculiar gray-green erect leaves, spread out in all directions over 
the white sand. I remember one place, several acres in extent, 
where this plant reached its perfection, the stems sometimes eight 
or nine feet long, fairly covering the ground in all directions, with 
hundreds of the flowers in sight. It is remarkable that a plant of 
such luxuriance and beauty can thrive in an area so devoid of 
moisture as the “scrub,” and yet it selects and confines itself ex- 
clusively to this region. Only one species of Cyperaceae is to be 
found here. Thisis Rynchospora dodecandra, and is quite common. 
Grasses there are absolutely none. For some reason this family 
is unable to obtain a foothold. Occasionally some member of the 
Andropogoneae tries it, but soon dies, not being able to stand the 
opposition it meets with for more than a few months. ,
