among names to accept for ourselves. Additional reference checking is still 

 necessary to complete the task of name assessment for legitimacy, appropriateness, 

 and proper citation. This list, along with others, including the recently com- 

 pleted Synonymized Checklist of the Vascular Flora of the United States, Canada, 

 and Greenland by John and Rosemarie Kartesz, constitutes a synthesis of much 

 nomenclatural information about United States tracheophytes. The real job that 

 still awaits doing is the flora of the entire IMited States for which this list 

 and its computer tape, we hope, can be an early contribution.
