EXCLUDED SPECIES. 



Graphephorum melicoideum major A. Gray. 



Reported from Portage Bay by Kurtz/* but certainly on a misconception of the 

 species and genus, as that species is not found west of the Great Lakes. 



AVENA 8ATIVA L. 



This cultivated species is reported & as collected at Dawson by R. S. Williams, 

 but it is only an escape from cultivation and should not be considered as a part of 

 the Alaskan flora.
