any specimens. As i have pointed out in my Flora Ellesm., p. 167, forms of P. ceni- 
sia may easily be confounded with this species. 
? Poa laxa, Haenke. 
Distribution. North Sonierset Port Kennedy, Wai.ker (ex Hooker, Exp. Fox); Baftin 
Land: Ponds Bay, Walker (ex Hookkr, 1. c); North Devon: »Lancaster Sound«, Lyall (ex Hoo- 
KKR, Coli.); Ellesmereland. Hart, Greely (compare Simmons, Flora Ellesm., p. 167). 
Geographic area. Greenland, northern North America, Aaia in the Bering Sea region 
and in the mountains of the central parts, mountains of Europé. 
Most probably all the above statements might be referred to P. cenisia, and I am, in fact, 
tainity be identified with it, and almost in every instance where it is recorded from some region 
or other, there is some doubt about it, or at least it is mentioned aa rare and sporadically occurring. 
forms of P. flexuosa^ (Fl. Bor. Amer., II, p. 246, siib P. arctica). But even i£ all records from 
arctic and northern alpine stations are transferred by right to P. cenisia, I think that some ame- 
rican records from the south (Macoun, Cat., p. 225) must have reference to quite different plants. 
25. Poa abbreviata, R. Br. 
Distribution. North Somerset- Port Kennedy, Walker (K H); [Melville 
Peninsula: Igloolik, Parrt (KH, NHM)]; Baffin Land: Port Bowen, J. C. Ross 
(NHM, KH); Melville Island, Edwards, Sabine, Fisher (NHM); North Devon: Po- 
well Creek (KH) and Beechey Island (KH, SH), Lyalt., Boat Cape, Schei, Cape Vera, 
Simmons (Stray Contr.); North Kent, Simmons (1. c); Ellesmereland, common, Hart, 
Feilden, Greely, Simmons; Wolf, Goodsell (ex Rydberg, List Peary). 
Geographic area. Greenland, Arctic America, No vaja Semlja, Spitzbergen, 
Franz Joseph Land. 
Besides the specimens, mentioned in the preceeding, there is one in the NHM 
from Parry'8 third voyage, and one in the LS in J. C. Ross' collection from the 
second. From the Continent I have only seen one specimen coUected at Point 
Drew by M'Clure (KH). According to Hooeer, Fl. Bor. Amer., p. 247, it is found 
by Beechey in Kotzebue Sound, and Macoun mentions it (Cat., p. 222) from the 
Pacific coast. Even if these statements are reliable, the distribution still seems to 
be very curious, as it is entirely wauting all over the Continental area of the old world. 
In the eastern parts of the Continent it seems to be wanting; the record from 
Labrador which 1 have taken up in my Flora Ellesm. from Ostenfeld, Flora Aret., 
p. 124, is based on a niistake of Macoun, 1. c, where the Port Bowen indication 
bas happened to be inserted under Labrador. 
26. Poa evagans, Si mm. 
Distribution. Ellesmereland: Fram Fjord on the south coast, Simmons, 
«Grant Land», Wolf (ex Rydberg, List Peary).
