27. Poa pratensis L. — On the clays on the north side of Nugssuaq 

 Peninsula the broad-leaved var. domestica Laest. attained a large 

 size: it grew for the most part solitary or in small clumps or 

 tufts. 



The var. alpigena of Blytt was, perhaps, the commonest. 

 f. prolifera. 



Near the trading place Niaqornat on the horders of small ponds,, 

 the water of which was stained by refuse from the Eskimo houses, 

 a viviparous form of Poa pratensis abounded. Probably the "proli- 

 ferous Poa''' recorded from Ellesmereland by Simmons p. 169, which 

 he with some doubt refers to Poa pratensis. My specimens formed 

 quite pure patches. 



While other species of the genus Poa f. inst. P. alpina and 

 others are often recorded as viviparous, and, under certain climatic 

 conditions, are only known in that state: vivipary does not seem 

 to be common in P. pratensis. At any rate I have seen no other 

 record in the literature. 



The records of viviparity in high-arctic species of Poa are inter- 

 esting for another reason, namely in relation to some old state-
