INTRODUCTION. 
A considerable amount of work has been done on the flora of 
the vicinity of Fayette since the early settlement, and during 
the last five years the writer has explored the region thor- 
oughly. Nearly 200 of the plants of this list have been care- 
fully compared by the writer and other persons at the herbaria 
of the University of Minnesota and Harvard university. I 
have also had the aid of specialists on five difficult genera, and 
altogether the list of a few more than 700 species and vari- 
eties has been carefully worked out. 
The early work was done by Dr. C. C. Parker who, previous 
to 1876, had collected and preserved nearly 500 specimens of 
our herbaceous plants. Dr. Parker’s herbarium contains 
twenty- eight plants not found by the writer, which are listed. 
They may be known, as he is given credit for the collecting. 
I am also indebted to him for the use of his herbarium in pre- 
paring this record, and for valuable aid in finding several rare 
plants. 
As to territory covered, the list is approximately complete 
for the region within five miles of Payette. A few plants are 
included which were collected ten or fifteen miles away, but 
the work is doubtless quite incomplete for some portions of 
Fayette county. This region furnishes a good field for the 
study of the higher plants, as the topographical features are 
quite varied. Prairies, woods, rivers, springs, marshes, ponds, 
hills and limestone ledges all abound. The woods, even after 
so much clearing has been done, are a more inviting field for 
study than the limited amount of unbroken prairie. Twenty 
years ago the prairie grasses and sedges were surely much 
more abundant than now, but unfortunately they were not
