6. Note on the Genus Graphephorum, Desv., and its Synony- 

 my. By Asa Gray. 



This communication announced the discovery by Dr. Charles Pick- 

 ering, in August last, at the Falls of the Riviere du Loup, in Lower 

 Canada, of the " Aira melicoides " of Michaux, on which Desvaux and 

 Beauvois founded the genus Graphephorum ; also that the Dupontia 

 Cooleyi, of the second edition of Gray's IManual of the Botany of the 

 Northern United States, proves to be a large variety of the same spe- 

 cies. Carrying out the view indicated in the Manual, Dr. Gray pro- 

 poses to dispose the genus — so extended as to include Dupontia, R. 

 Br., Scolochloa of Link, and Arctopkila of Ruprecht — as follows : —
