JANUARY, 1902. BENNETTS ADDITIONS TO THE FLORA OF MILWAUKEE CO. 39 
Additions to the Flora of Milwaukee County. 
By W. J. BENNETTS. 
A Third Supplement to " The Flora of Milwaukee County" by W. M. Wheeler. 
The following list is in part based on collections and observa- 
tions made by myself during the past season of 1901. About one- 
third of the c)o names mentioned, however, have been contributed 
by five of our local botanists, viz. : W. Finger, P. Wells, H. Rus- 
sel, J. A. Brandon and E. Bruncken. Acknowledgment is espec- 
ially due to Mr. Finger who has furnished 19 of the species listed. 
A notable feature of this list is the comparatively large num- 
ber -of western species — about 10 may be placed in this class — that 
the railroads have brought into this region. Some of these, like 
Allionia nyctaginca and Artemisia gnapJialodcs, have apparently 
firmly established themselves, and may in time bring about a con- 
siderable change in the composition of our local flora. Hence 
lists which record the appearance of such species in our midst 
should prove of much interest to future botanists. 
The nomenclature followed is that of Britton & Brown's ''Illus- 
trated Flora of the Northern United States and Canada" edition 
of 1898.
