August 24, 190S, ./. G. McMillan, herb. Geo]. Surv. Can. no. 77,271; 

 and Melville Island, 1820, Edwards (original collection of Poa angus- 

 taia). 



Yar. alaskana both in the East and the West has also been frequently 

 identified with Presl's Poa nutkaensis, originally described from Van- 

 couver Island. A fragment of the original Haenke material which 

 was Presl's type, sent to Dr. Gray, shows, however that Poa nutkaensis 

 has strongly scabrous branches and pedicels and that the glumes and 

 lemmas are erose-ciliolate. The plant is more nearly related to Pucci- 

 neUia macra than to any other species but differs in its firmer and less 

 pubescent lemmas which are usually quite glabrous above the base. 

 Poa nutkaensis seems to be a distinct species of the coast of Vancouver 

 Island which should be called Pueeincllia nutkaensis. 1
