August 24, 1908, J. G. McMillan, herb. Geol. Surv. Can. no. 77,271; 
and Melville Island, 1820, Hdwards (original collection of Poa angus- 
tata). 
Var. alaskana both in the East and the West has also been Fescmmthe 
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- 
nellia 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 Puccinellia nutkaensis.!
