PREFACE.

This handbook contains descriptions of the seed-plants growing natu-
rally in the Miami Limestone Region. This area consists of a chain of lime-
stone islands enclosed by the southern portion of the Everglades, except
where some of the islands come in contact with the upper half of Bay
Biscayne. The chain stretches, in crescent form, from somewhat north of
the Miami River southwestward toward Cape Sable for a distance of about
fifty-five miles. The islands, apparently, in ancient times formed a part
of the Antilles. Their native vegetation is essentially of a tropical char-
acter, with strong relationships to the flora of Cuba and of the Bahamas.
As far as the native flora is concerned the Everglade Keys represent a
small tropical area isolated on the mainland of the United States.

The vegetation of the islands themselves is divided into two rather
distinct plant-associations, namely, pineland and hammock, which are
usually sharply differentiated from each other. These in turn are both
rather abruptly marked off from the adjacent Everglades. With few
exceptions the individual plant-species are distributed generally over the
area under consideration. However, they are, in the majority of cases,
confined to the one or the other of the plant-associations; consequently, on
the following pages the local distribution of the species is indicated as
" Pinelands," " Hammocks," " Everglades."

In addition to the area already described, two minor elements are
included in our geographical range, the coastal sand-dunes of the narrow
peninsula opposite Miami and also those of Virginia Key and Key Biscayne
and the waters of Bay Biscayne itself.

As the plant-life of the Everglade Keys is closely related to that of
the Florida Keys, when a species is common to both, the fact is indicated
in this flora by "F. K." (Florida Keys) following the habitat. The
relationship of the plant-species of the Miami flora to the flora of the
West Indies is also indicated; if a species grows on one or more of the
West Indian islands, it is indicated by " Ber." (Bermuda), "Bah." (Ba-
hamas), "Cuba" and if it also occurs in other parts of the West Indies
it is indicated by "Ant." (Antilles).

The flowering and fruiting seasons are not indicated ; the plants flower
most abundantly in spring and summer, and produce fruit in due time, and
although most or essentially all of the rainfall normally occurs from late
spring to early fall, the relative high and even temperature of the other

Hi

half of the year and the generally close proximity of the water-table to
the land-surface make a rather continuous flowering and fruiting season
for all vegetation.

The specimens on which this flora is based are preserved in the her-
barium of the New York Botanical Garden, and the exploration work which
has made this study possible was carried out under the auspices of that
institution. The botanical exploration of the West Indies, carried on at the
same time by the New York Botanical Garden has rendered possible the
detailed indication of the geographical distribution of the species.
