Indeed, tfie arctic Glyceriae which, following the example of Gelert, 

 I have here referred to G. distans, are rather different from one an- 

 other, the typical form with the long, reflexed panicle-branches is hardly 

 found in any arctic station, and I have seen transitions from it to the 

 arctic forms only from Iceland, but nevertheless I think they must all 

 be united, as there are no clear distinguishing marks between them. 

 Among my specimens, there are two forms, var. arctica, (Hook.) Gel., 

 and var. vaginata, (Lange) Gel. The third Greenland form, which 

 Lange has identified with Sclerochloa Borreri, Bab., I have not found. 



G. distans is a rather common grass especially in clay plains, also 

 in rookeries, but generally not where the vegetation is very dense. 

 Flowered late, hardly before the end of July. 



Occurrence. Var. vaginata: South coast, Goose Fjord, rather 

 common in the clay fields; specimens from Ptarmigan Gorge (3387), 

 east of 3rd quarters (3436, 3478), Yellow Hill (3585), Castle Point (3819). 

 Var. arctica: Grinnell Land: Discovery Harbour (Hart!). Hayes Sound 

 region: Skrahng Island (1378), Fram Harbour (4240), Cocked Hat Island 

 (1890), Brevoort Island (1209), South coast : bottom valley of Fram 

 Fjord (1668), Barren ValHes in Harbour Fjord (2394), east side of 

 Muskox Fjord (2149). G. distans is further noted from several places 

 in the Goose Fjord and from the West coast; along the Hell Gate to 

 Lands End, between Eidsfjord and Baumann Fjord, Coal Bay; probably 

 these localities may be referred to var. vaginata. 



Distribution. The arctic varieties seem to be distributed only 

 in Greenland (both coasts), Arctic American Archipelago, Arctic coast 

 of America, Arctic coast of Asia, Arctic Russia. AlUed forms are found 

 in Iceland and the Faeroes. The main form is spread all over Europe,
