STUDIES IN TRIFOUUM I. 

 By P, Beveridge Kennedy 



Some two or three years ago we became interested in the 

 genus Trifolium, with the purpose more especially of attempt- 

 ing to introduce into cultivation some of our excellent annual 

 and perennial species. The literature concerning the clovers 

 seemed to be in so unsatisfactory a condition that little progress 

 could be made along any line of investigation without first in- 

 quiring into the validity of the species. We found that some 

 careful and conscientious work was necessary, including much 

 field and culture work before a revision of the genus could be 

 made that would stand the test. Furthermore, it was soon 

 made apparent that thorough work would necessitate the exam- 

 ination and comparison of the types of American species depos- 

 ited in European herbaria. This we intend to do before pub- 

 lishing the final monograph. 



Many friends, however, who have loaned us specimens and 

 aided in other ways, are anxious to know what to do with their 

 clovers, and are awaiting our publication. ' In view of these 

 facts we intend to take up the various sections in a preliminary 

 way, so as to open our views for discussion. 



These discussions could not very well be published in a 

 monograph. Their object will be to try to get as near the truth 

 as possible before presenting any work in a permanent and com- 

 pleted form. We invite discussion and criticism, either by per- 

 sonal letter or for publication. The first papers will include a 

 review of the species belonging to the Amoria section Found 

 growing spontaneously or under cultivation in America north 

 of Mexico.
