1898-1902. No. 16.J FLOW. PLANTS AND FERNS OF N.-W. GREENLAND. 105 



It must be taken for granted, I think, that the plant from Ingle- 

 field Gulf in WETHERILL'S list is really the same as that found in the 

 northern, western and southern parts of Ellesmereland as well as in 

 other parts of the Arctic American Archipelago. It is indeed curious, 

 that it should be absent from just that part of Ellesmereland which lies 

 nearest to the Smith Sound region of N. W. Greenland. However, even 

 if it does not grow in the Hayes Sound district it may perhaps exist in 

 the little-known region down to Clarence Head; and at all events, there 

 are other species lacking, or rare, in the Hayes Sound region, which are 

 common to the south coast of Ellesmereland and the southern part of 

 N. W. Greenland. Moreover, the plant here in question is also found 

 in North-Eastern Greenland. I therefore think it best to give it a place 

 in the list on the authority of WETHERILL, although I wish very much 

 that I could first have made an examination of it, the more so as it is 

 not only in itself critical but there is also the following still somewhat 

 doubtful species, to which it might be referred. 



Occurrence. S. Inglefield Gulf: Gape Acland (WETHERILL). 



Aira flexuosa,, L. 



A. flexuosa, SIMMONS, Fl. Ellesm. 



The Aira. which NATHORST collected at Ivsugigsok in 1883 and in 

 N. W. Gronl., p. 27, refers to the same plant that ROB. BROWN had 

 described in Ghlor Melv. as Deschampsia brevifolia, has given me a 

 good deal of trouble, as has also my own plant from Fram Harbour in 

 Eastern Ellesmereland. They are very like each other, the principal 

 difference being that my plant has all the leaves flat, NATHORST'S has 

 them generally convolute. Both differ from the common A. flexuosa 

 in possessing a short awn, which is not, or at least very little, excerted 

 beyond the glume. But in other respects they agree with that species 

 far more than with A. caespitosa, and they call to mind especially the 

 form which BERLIN, Karlv. sv. exp. Gronl., p. 77, has called A. flexuosa 

 var. montana f. pallida, which has the same short, straight, included 

 awn. For the present, until a better material can be procured by some 

 future collector, I must, even if I cannot do so without some hesitation, 

 let it stand where I placed it in my Ellesmereland flora. 



NATHORST, however, in the same paper, speaks also about another 

 Aira, which he found on Hare Island in Danish Greenland and referred 

 to the same variety, although he speaks of differences between them. 

 As I have previously mentioned (Dan. Greenl. PI., p. 473), this is in fact
