Poa pratensis L. — On the clays on the north side of Nügssuaq 
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. alpıgena of Blytt was, perhaps, the commonest. 
f. prolifera. 
Near the trading place Niagornat on the borders 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 р. 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-
