Seemed to be rather common in the regions about the river Abakan, where 

 gathered by me in several places near Ust Kamuishto and Askys. In full flower in the 

 second half of June. I have also collected it in the Urjankai country, at Ust Algiac. 



The specimens agree perfectly with authentic materiel collected in Norway and 

 determined by the author himself under the name of Poa alpestris. 



Distribution: The species was formerly only recorded from Scandinavia and the 

 Pyrenees (?).
