PREFACE TO FIRST EDITION. 

THE following Catalogue was undertaken because I believed that « 
record of the names, and a description of the localities of the plants 
growing without cultivation in the State of New Jersey, would be a use 
ful book to students of Botany, as well as to Botanists and collectors of 
Plants all over the country. 
Having collected largely, and eeanitned with great care, the Flora of 
the State, I began to prepare materials for a catalogue, and communicated 
my design to the late Dr. Torrey, who encouraged me to go forward, giv- 
ing me a list of plants which he knew to be indigenous, and furnishing 
me with other important information. 
The late Dr. P. D. Knieskern made a careful examination of the eastern 
site of the counties of Monmouth, Ocean, and Burlington ; and furnished 
me with many of the interesting plants found in the pine regions. He 
made a specialty of the Cyperacez and Graminezx, and many of the mem- 
bers of these orders are introduced on his authority. 
Iam also indebted to Prof. Geo. H. Cook, Vice President of Rutgers 
College, Wm. M. Canby, of Wilmington, Delaware, and Prof. Porter, of 
Lafayette College. 
Prof. Samuel Lockwood, of Freehold, furnished me with plants grow 
ing on the shores of New York Bay in the vicinity of Key-port. 
Iam under special obligations to Rev. Dr. Knighton, of the Brainerd 
Institute, for much information regarding the Flora of the Northwestern 
parts of the State, and for other valuable assistance. 
The localities of rare and curious plants have been carefully noted, and, 
for the convenience of inexperienced Botanists ‘and collectors, general 
localities have been described, such as: dry soils—damp, shady woods—- 
hill-sides—open woods—meadows—wet grounds—swamps, etc.
