beeches. In a broad strip through the county, from north¬ 
west to south-east maples predominate. In the south central 
and south-western parts oaks prevail. In the southern part 
of the county grasses and sedges represent the prairie flora, 
which has extended into the county a little distance from the 
south and west. 
The pine flora, so well developed in the northern part of 
Wisconsin and which extends down to the lake shore of 
Ozaukee county has sent a few straggling specimens into the 
extreme northeast corner of our county near Whitefish Bay. 
The tamaracks, formerly common in different parts of the 
county are fast disappearing. 
Of the 691 Phaenogams and vascular Cryptogams compos¬ 
ing my list, 567 are indigenous to Wisconsin. These, with 
the exception of Trade scantia Virginia a , Iva xanthiifolia and 
possibly a few others, are also indigenous to the county. The

from Waukesha county where it is abundant in some places ; 
the seeds of the latter have probably been accidentally trans¬ 
ported from the northwestern part of the state. 
The remaining 124 species marked with an asterisk in the 
list, have been introduced. Of this number, seven species . 
Argemone Mexican a, Cleonie pungens , Hclianthus anmiiis , 
Nicotiana rustic a , Arnaranthus hypochondnacus , A. refit xus 
and A. albus , have come from Tropical Ameiica , one species, 
Onosmodium Carolinianum y is from the Southern States, one 
species, Polygonum maritimimi , from the Eastern States, one 
species, Grindelia glutinosa from the Western States (Cali 
fornia) and one, Galinsoga parviflora , is from South America. 
Subtracting these eleven species from the total number o 
introduced species we get the number of species fiom Europe,

Of the whole 124 introduced species, seventy five 
escaped from gardens, where they were cultivated for
