24 H. G. SIMMONS. [sec. arct. exp. fram 



Found only June 6th, 1899 with stems of last year. The fruit 

 seemed hardly to have been developed. 



Grew in somewhat boggy, shallow soil on the surface on lop of a 

 rock, about 200 feet above sea-level. 



Occurrence. Eastern coast: Hayes Sound, on a promontory at the 

 mouth of Flagler Fjord (490). 



Distribution: East Greenland, West Greenland, Arctic American 

 Archipelago, Arctic America, Labrador, Rocky Mountains, Arctic Asia, 

 Altai a. o. mountains, Arctic Russia, Northern Scandinavia, the Alps, 

 Iceland.

As I did not find this species either on the south or east coast, I 

 have only seen some specimens collected by Hart at Discovery Har- 

 bour. These agree with E. eriocephalus, J. Vahl, which is, however, 

 only a variety of E. uniflorus, differing principally in the dense villo- 

 sity of the upper part of the stem and the bracts (cf. Berlin, Karlv. sv. 

 exp. Gronl., Rosenvinge, 2 Till., and Hartz, Fan. o. Karkr., p. 339 sub 

 E. eriocephalus). Still, it is possible that Greely's specimens are the 

 principal form. 



Occurrence. Grinnell Land, Discovery Harbour in Lady Franklin 

 Bay, Hart (!), Greely. 



Distribution: East Greenland, West Greenland, Arctic American 

 Archipelago, Arctic America, Labrador, Unalaschka, Arctic and Eastern 

 Siberia, Altai and other mountains, Arctic Russia, Novaja Semlja, Spits- 

 bergen, Northern Scandinavia, the Alps and other European mountains.

Of this species also, I have only seen Hart's specimens in the her- 

 barium of the Nat. Hist. Mus. and at Kew. It was missing in the 

 southern parts of the land, which is the more astonishing, as it seems
