34 REPORT OF NEW JERSEY STATE MUSEUM. 



popular works of like character. The present work is tO' be re- 

 garded as supplementary to these, to show exactly what species 

 are present in southern New Jersey and their distribution and 

 relative abundance. 



Popular or historical accounts of some of the more striking or 

 noted species are added, however, and to meet the request of the 

 Museum authorities, keys, which are in some cases unavoidably 

 based on the same characters as those of the manuals, but in 

 others largely original and supplementary to the latter have been 

 prepared, and vernacular names given for each species. 



So far as the resources of the library of the Academy of Nat- 

 ural Sciences of Philadelphia have permitted, the original place 

 of publication has been looked up, the reference verified and the 

 type locality stated. Where the latter is general or where several 

 localities are mentioned no attempt has been made to sift the 

 matter to the bottom, since this usually involves the selection or 

 examination of a type specimen, as so admirably explained in 

 Hitchcock's paper on the types of North American grasses and 

 in the monograph of the genus Panicum by Hitchcock and 

 Chase. About one hundred additional references to volumes 

 not in Philadelphia were verified at the New York Botanical 

 Garden with the courteous aid of Dr. J. H. Barnhart, and a few 

 others at Cambridge by Prof. M. L. Fernald. Only one refer- 

 ence remains unverified (p. 527). 



As to nomenclature the botanist in America, at least, is on the 

 horns of a dilemma. He can follow either the Vienna Code* or 

 the American Code.f Should he be also a zoologist he will prob- 

 ably find it quite impossible to accept certain of the features of 

 these codes which are at variance with the International Zoologi- 

 cal Code (virtually identical with the A. O. U. Code). 



The broad problems of Zoological and Botanical nomencla- 

 ture are identical. The zoologists have been "playing the game" 

 seriously, longer than the botanists, and it seems logical to infer 

 that, with the same tools to work with and the same object in 

 view, men of the same intellectual ability will eventually adopt
