The list of plants included in this paper is the result of the 
work of three seasons. During that time fully five thousand 
specimens have been examined. All plants admitted to this 
list have passed through the hands of the authors; therefore, 
they only are responsible for errors. 
On account of lack of time during the early part of the season 
it has been impossible to make a systematic study of the difficult 
genus, Salix. It is expected to give to it a thorough study dur¬ 
ing the coming season and a report upon it will be made in a 
later paper. 
For the convenience of collectors and others to whom it will be 
of use, a map of Madison and vicinity is included with the list. 
It is based on the topographical atlas sheets of the United States 
Geological Survey and has been brought up to date in regard 
to roads. It is hoped that it may serve as a practical field 
guide to collectors. 
In nomenclature the sixth edition of Gray’s Manual has been 
followed in all cases. The reason for so doing has been that of 
convenience, as this is the manual most in use here. 
In general arrangement we have followed the same work with 
a few exceptions. For Phanerogamia, the term Spermaphyta 
has been used. The Gymnosperma: have been placed between 
the Monocotyledones and the Pteridophyta. In the minor de¬ 
tails of classification the manual has been followed in all partic¬ 
ulars. We again make convenience the reason for so doing with¬ 
out thereby expressing any opinion of our own. 
At the suggestion of Dr. Edward Kremers, of the Pharma¬ 
ceutical Department of the University of Wisconsin, we have 
indicated, for the convenience of students of Pharmacy, the 
medicinal plants occurring in this region. We have designated 
the unofficinal medicinal plants by one asterisk before the name of 
each, and those officinal by two asterisks. Whenever the name
