Mårtens, Ueberblick, p. 20, records it for Port Bowen, but has omitted North 
Somerset.

Mårtens, UeberbUck, p. 20, records this species for Port Bowen, but I do 
not believe that it is found there, as his source, Hooker, App. Parrt III, only 
gives North Somerset as the locality of Pleuropogon. Mårtens seems to have thought 
all plants from Parrt's second expedition to have been collected at Port Bowen, 
and consequently 1 shall in the following exclude the records from there, when no 
other authority exists. 
22. Poa pratensis, L. 
Distribution. Ellesmereland: Skräling Island and Cape Viele in the Hayes 
Sound region, prohferous forms in the Fram and Goose Fjords on the south coast, 
Geographic area. Greenland, western arctic and temperate North Ame- 
rica, most parts of Asia, the whole of Europé, southern South America. 
In my Flora Ellesm. I have raentioned this species as occurring in North 
Devon, but I now think this to be an error. The specimen in the SH which I did 
then identify as P. pratensis is the same as now mentioned under P. cenisia, collec- 
ted by Lyall at Beechey Island. The two species are, in fact, very difficult to 
distinguish, especially when they appear in the prohferous («viviparous«) state. As 
pointed out (1. c, p. 169) I am in doubt even about the specimens from the Jones 
Sound localities referred to P. pratensis.
