Poa stenantha Trin. is reported in Hooker's Flora as collected on Mount Rainier by 

 Tolniie. No recent collections made in Washington seem referable to this Alaskan species, 

 though its occurrence would not be surprising. 



Poa caesia Smith and I^oa nemoralis L. both appear in Suksdorf's list, but we have 

 seen no specimens that can be so referred.
