The northern hmit, as previously known, was 70° 7Г, while on 

 the east coast it extends further north. 



18. Calamogrostis neglecta (Ehrh.) Fl. D. Wett f. horealis 

 Lange. On the edge of pools and in damp moss along streams. 

 Schade's Islands, 71° 22': rare. Igdlorssuit: very rare. 



14. Tri se tu m spicatum (L.) Richter. Observed everywhere, 

 and is undoubtedly common on every somewhat luxuriant heath, 

 rock-formation or copse-margin. In favourable localities it becomes 

 fairly tall and the panicle is composed of several compressed and 

 juli form branches. 



Fig. 10. Aira cœspitosa var. piimila Ledeb. Portion of a tuft witli a new panicle 

 emerging and the remains of one from the previous year. 



15. Aira cæspitosa L. var. pumila Ledeb. Fl. Ross.; Osten- 

 feld in Ostenfeld & Lundageh, p. 12 (see Fig. 10). At the outermost 

 of the lakes which occur within the head of Amitsuarsuk Fjord a 

 small mountain stream had formed rather a large delta on the nor- 

 thern shore of the lake. The greater part of the delta was covered 

 with masses of ice from the stream even late in July, and the vege- 

 tation was that which usually occurs in such localities. Along the 

 margin of the delta and facing the lake, there was a broad border 

 of a fine, green grass. It was as yet almost sterile everywhere, only 

 in a few places the panicle was just on the point of emerging, but 

 the old, dead panicles showed that it flowered and set fruit in 

 favourable years. 



The plant corresponds closely with the description given by 

 Ostenfeld (I.e.) and by Simmons in Vase. PI. Ellesm., p. 175, and
