Some "reformed" spellings of English words have been nsed< 



The only really intensive study has been made on 

 the extremely "variable" genus Dentaria « fhe work, con- 

 ducted as part of a "minor" subject, is hardly sufficient 

 as the basis of a paper for publioationf except perhaps 

 (with further elaboration) in the case of Dentaria . Con- 

 sequently it has appeared desirable to include much mater- 

 ial that would not appear in a publlsht paper, bringing 

 together in a sort of "essay" form such facts, from var- 

 ious authorities as well as from the writer's specimens, 

 as will make the paper most useful for reference^ to stud- 

 ents of the Gayuga flora. 



The Gruciferae specimens in the Local -Flora Herb- 

 arium have been rearranged where necessary, and a few 

 needed corrections have been noted on the sheets. A 



» 



considerable number of the specimens discust in the fol- 

 lowing pages are to be added to the collection* A key 

 not using fruit -characters has been constructed for the 

 determination of the genera of the Gruciferae represent- 

 ed in the Gayuga flora. 



The work has been done under the direction of 

 Prof. W. W. Rowlee, to whom grateful acknowledgement is 

 due for many helpful suggestions relating to the plan- 

 ning of the work and various details of its accomplish-
