nated in this "way. The extensive living collection of alfalfas which 

 the department has in its possession furnishes an opportunity for 

 studying the variations that is not afforded by the herbaria of the 

 country and makes it possible to gain a conception of the group as a 

 whole that can not be gained from a study of dried material. 



Partial lists are given here of the botanical names that have been 

 applied to what appear to be forms of true Medicago falcata, to 

 hybrids of Medicago falcata and Medicago sativa, and to species and 

 varieties whose origin and relationship to Medicago falcata are not 

 clear, together with a brief description of the forms in question. The 

 localities in which the various forms were collected are in most cases 

 indicated in the descriptions.
