wither at the time of the collection (July 26, 1899). Probably both 

 kinds of stems appear about the same time, the fertile ones perhaps a 

 little earlier. It grew among moss in svamps or inundated places. 



Occurrence. Grinnell Land: Bellot Island, Discovery Harbour 

 (Hart, Greely). Hayes Sound region: (recorded by Hart), Rutherford 

 Vallies (1160). South coast: Harbour Fjord in the Big Valley (2340), 

 interior of the Muskox Fjord (2118, 2138). 



Distribution (all forms together): East and West Greenland, 

 Arctic American Archipelago, Arctic America, Rocky Mountains, and 

 down to Virginia and California, Alaska, Unalaschka, Pribilof Islands, 

 Northern and Central Asia, all over Europe, Novaja Semlja, Spitsbergen, 

 Jan Mayen, Faeroes, Iceland, North Africa, Cape Colony.

I am a little doubtful about this plant, as I have seen no Elles- 

 mereland specimens of it. However I may have forgotten, during my 

 stay in London, to look for Hart's specimens, and as a confusion with 

 the preceding one is hardly to be thought of, I enter it here on the 

 authority of Hart and Greely. Its occurrence in Greenland (for in- 

 stance in the north-eastern coast) and in the Parry Islands, also tells 

 in favour of the possibility of its existence in Grinnell Land. 



As to the name, there is a difficulty about that also; a name exists 

 from 1798, E. Memale A, tenellum, Liljeblad, Svensk Fl., p. 384, 

 which Krok in Hartman, Skand. FL, Ed. 12, has adopted for the species. 

 But this name may equally well apply to E. scirpoides, Michaux, 1803. 

 Indeed, when E. variegatum, and the last-mentioned are considered as 

 belonging to one species, there might be the question of adopting the 

 name of Liljeblad for it, but I think that it is better to use the other 

 names, the meaning of which is not subjected to any doubt. 



Greely, 1. c, mentions clay and loamy soil as the habitat, and 

 adds "infertile". 



Occurrence. Grinnell Land: Discovery Harbour, Mount Cartmel 



(Hart, Greely).
