the removal of the forests and other "improvements" the fame of 

 that region will ere long depart. The same is true of other areas, 

 indeed, wherever the woods are being cut away, the swamps 

 drained, and similar changes going forward, it must follow that the 

 botanical riches of the region diminish. Another change in the flora 

 is going on here as elsewhere because of the introduction of 

 western and other plants in grass seed. Even during so short a 

 period as the last ten years there has been a marked change in the 

 aspect of many acres of meadow and grass land as Rudbeckias, 

 Hieraciums, and similar plants have not only appeared, but so in- 

 creased as when in bloom to change the appearance of the fields in 

 which they have become located. In a much less degree the flora 

 is increased by the escape from gardens from time to time of species 

 which are able to care for themselves and lead a sort of vagrant life 

 by roadsides or about dwellings. In these ways our flora is chang- 

 ing and on the whole increasing. In Oakes' catalogue of 1842 there 

 are enumerated 929 species, to which Prof. Torrey's list of 1853 

 adds 105 species, making in all 1034. Quite a number of these 

 must be erased as erroneovis, either in identification or classification, 

 so that if the list were revised according to the views of the 

 botanist of to-day, it would not contain many more than 1000 

 species. The present list contains 13G0 species and varieties in- 

 cluded in 479 orders. The species are found in the following great 

 groups : Polypetalse, 372 ; Gamopetalae, 360 ; Apetalae, 133 ; Mono 

 cotyledons, 409 ; Gymnospermae, 15 ; Pteridophytes, 72. 184 of 

 the species are trees or shrubs, 110 are introduced and are dis- 

 tinguished by the use of small capitals in printing the names. 



For the covenience of botanists wishing to compare our flora 

 with that of other regions, the statistics of a few of the larger orders 

 and genera are added in the following tables, varieties being included
