JULY, 1900. BENNETTS— ADDITIONS TO THE FLORA OF MIL. CO. 161 
Additions to the Flora of Milwaukee County* 
By J. BENNETTS, 
A Second Supplement to M. Wheeler's Flora of Milwaukee County/' 
In 1888, a list of the flowering plants and ferns of Milwau- 
kee county by W. M. Wheeler, then curator of the Milwaukee 
Public Museum, was published in the transactions of this society. 
It contained the names of 691 species and was followed in 1889 
by a supplementary list containing 58 additional names. 
Since that date no work appears to have been done in the 
way of cataloguing our Milwaukee wild plants until the past year, 
T899, when the botanical section of the Milwaukee Natural His- 
tory Society inaugurated among its members what might be 
termed a "co-operative card catalogue" system of collecting and 
recording facts relating to our local flora. As, however, it will 
be several years before sufficient data can in this way be accu- 
mulated to warrant the publishing of the elaborate report this 
system appears to render possible, it has been thought best to 
publish at intervals the names of such additions to our flora as 
have become known since the publication of the previous list. 
The list which follows contains 82 species, bringing the num- 
ber thus far recorded for Milwaukee county up to 831. In com- 
piling it, the writer has had the cheerful co-operation of three of 
our local botanists. Dr. S. Graenicher, and Messrs. Ernest 
Bruncken and Philip Wells. Dr. Graenicher has contributed the 
follo,wing 10 numbers of the list: 769, 770, 778, 780, 800, 804, 
820, 823, 826, 831. Mr. Wells furnished 14 names, viz. numbers 
753. 754, 764, 772, 776, 781, 788, 794, 796, 802, 803, 821, 82S, 
830; while the following 11 were supplied by Mr. Bruncken: 
numbers 760, 763, 779, 799, 806, 808, 809, 810, 811, 812, 813. Of 
the remaining 47 numbers 45 were supplied by the writer and 2 by 
P. H. Dernehl. 
An examination of this list of plants shows that they admit 
of being arranged into 4 classes. In the first class can be placed 
those species that have been introduced from Europe or Asia. 
Some of these are troublesome weeds like the Russian Thistle 
Salsola Targus, L.), the remainder are in general plants 
that have escaped from gardens or from cultivated fields. 
This group contains 21 species as follows: Anagallis 
arvensis, L., Aquilegia vulgaris, L., Bromus hordeaceus, 
L., Crateagus Oxyacantha, L., Echium vulgare, L., Eragrostis
