INTRODUCTION. 

The results embodied in the accompanying catalogue are 
based on specimens in the College herberium, and on notes 
taken in the field by Professor T. A. Williams and the writer. 

The nomenclature followed is the modification of the Paris 
Code adopted by the Botanical Club of the American Asso- 
ciation for the Advancement of Science at Rochester in 1892 
and amended at the Madison, Wis., meeting in 1893. The 
only synonyms given are such as would be a help to one' 
accustomed to using Gray's Manual. 

In preparing this catalogue, Dr. P. A. Rydberg's Flora of 
the Black Hills* has been freely used. Specimens have also 
been received from various collectors in that region. Pro- 
fessor Williams has made extensive collections in the Sioux 
valley, has done considerable work along Bigstone Lake, and 
has made one trip from Pierre to Rapid City and return, 
obtaining many interesting specimens, especially from the 
Bad Lands. Messrs. David Griffiths, Earl Douglass, Jno. J. 
Thornber, students of Professor Williams, have done consid- 
erable collecting east of the Missouri river. Mr. L. W. Carter 
has made various collecting trips in the eastern part of the 
state, and, in company with Mr. Griffiths, one extended trip 
from Forest City along the Moreau river to the Black Hills, 
returning along the Cheyenne river to Fort Pierre. The

writer has collected over most of the state east of the Missouri 
river, and, in company with Mr. J. R. Towne, in the sum- 
mer of 1897 made very careful examinations of the Little 
Minnesota river and its tributaries. On this trip many eastern 
species heretofore unknown to the state were obtained. 

Acknowledgment is due Dr. N. L. Britton, Dr. P. A. Ryd- 
berg, and Messrs. Nash and Bicknell of the New York 
Botanical Garden, Dr. L. H. Bailey of Cornell University, and 
Professor Sargent of the Arnold Arboretum for the verifica- 
tion and determination of certain species.
