Poa sTENANTHA Trin. is reported in Hooker's Flora as collected on Mount Rainier by 
Tolmie. No recent collections made in Washington seem referable to this Alaskan species, 
though its occurrence would not be surprising. 
Poa cagsta Smith and Poa Nemorauis L. both appear in Suksdorf’s list, but we have 
seen no specimens that can be so referred.
