The Flora of New Jersey is very large, possessing about the same 
number of individuals as the extensive territory of the State of New | 

York, whose Flora is regarded as remarkable for its extent, embracing — 
“oy as many species as the whole of New England. : 
* This Catalogue enumerates 1,603 species of Phznogamous plants, 40 _ ™ 
species of Equisetacez, Filices, and Lycopodiacee, and 28 species of a 
marine alge. (There are 325 species of Musci, and 100 species of He- y 
ee patice found within the limits of the State, not herein named), making 
aD an aggregate of 2,196 species. : 
Of these there are : 
57 species of first-class trees, 
37 species of second-class trees, 
128 species of shrubs. 
One of the most remarkable features of this Flora is, that with a few 
exceptions, all the plants growing in the State have representatives in 
the middle counties, a territory less than fifty square miles in extent. 
Many localities are given upon the authority of the ‘‘ Bulletin of the 
Torrey Botanical Club,” and the botanists and naturalists whose names 
are found throughout the pages of the Catalogue. a |
