HEAD CURATOR OF THE MUSEUMS AND HERBARIUM OF THE NEW YORK BOTANICAL GARDEN: LIBRARY NEW YORK PUBLISHED BY THE AUTHOR 1913 Copyright, 1913 By John Kunkel Small Press of Tke new era Printino compant Lancaster. Pa. LIBRARY NEW VORK BOTANICAL GARDEN 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 Evei'glades, except where some of the islands come in contact with the upper half of Bay Biscayne. The chain stretches, in crescent form, fi'om 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 eases, 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 oi")posite 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 sj^ecies 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). tf*5 The flowering and fruiting seasons are not indicated; the plants flower CTi 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 tempex'ature of the other iv PEEFACE 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 presei'ved in the her- barium of the Xew 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, caii-ied on at the same time by the New York Botanical Garden has rendered possible the detailed indication of the geogTaphical distribution of the species.
