PREFACE. 



TnE following Catalogue was undertaken because I believed that a 

 record of the names, and a description of the localities <>f 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. 



Haying collected largely, and examined with great care, the Flora of 

 □ 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 

 parts 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 Cyperacea? and Graminese, and many of the mem- 

 bers of these orders are introduced on his authority. 



I am also indebted to Prof. Geo. H. Cook, Vice President of Rutgers 

 College, Win. M. Canby, of Wilmington, Delaware, and Prof. Porter, of 

 Lafayette College. 



Prof. Samuel Lockwood, of Freehold, furnished me with plants grow 

 ing on tie : New York Bay in the vicinity of Key-port. 



I am under Bpeda] obligations to Rev. Dr. Knighton, of the Brainerd 

 Institute, for much information regarding the Flora of the Nbrthwi 

 :' the Stat*-, and for other valuable assistance. 



The f ran- and curious plants have been can-fully noted, and.
