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
