Widely spread in EUesmereland but appears sporadically and is 

 very variable in different localities. The rarest is the common european 

 form, with low arched culms such, as it is found in our shores and also 

 in alpine stations. This, however, may be found in sandy as well as in 

 clayey localities. Some of my specimens agree rather well with the 

 var. ereda, Lang, Car. germ, et scand., but in most cases they represent 

 intermediate forms between these. 



A characteristic form I collected in a pool at an old Eskimo tent- 

 place near Cape Viele; I think it differs sufficiently from other forms 

 to have a right to a name. 



Var. inflata, n. var.: rhizoma longum inter muscos in aqua libere 

 natans, cuimus erectus, valde inflatus, spica subglobosa. 



My specimens, collected July 4, 1899, had fruits from the preceding 

 yea)-. Besides the strongly-inflated culm and the dark brown, also very 

 much inflated utricles, it differed from other forms principally in the 

 unusual mode of its growth. 



G. incurva flowers rather late but sometimes fruits richly. In 

 some places only found sterile. 



Occurrence. Main form: Grinnell Land, Discovery Harbour 

 (Hart!). Hayes Sound region at the south side of Fram Harbour 

 (641, 1126), Cocked Hat Island (4250). South coast, more common: 

 Fram Fjord in several places, on the sandy shore and along rivers 

 (1611, 1670); Harbour Fjord, Seagull Rock (near var. ereda, 2578); 

 Goose Fjord, at the Yellow Hill. West coast: Coal Bay in Baumann 

 Fjord. 



Var. ereda: South coast. Harbour Fjord in wet, grassy ledges at 

 the "green patch" (2237, 4005).
