have been previously overlooked or confounded with other species. For 

 my own part, I found very little of it. 



Occurrence. S. Gape York (STEIN); Ivsugigsok (NATHORST); North- 

 umberland Island in Inglefield Gulf (STEIN); Foulke Fjord (4199).

 INGLEFIELD, Summer Search ; MEEHAN. Gontr. Greenl. ; I), rupestris, Dim-

 iica, NATHORST, N. W. Gronl.]. 



This species also is so confounded with others by the authors, that 

 it is very difficult to give any detailed statements about its occurrence 

 within the area. It may, however, be taken to be fairly common. My 

 specimens and those of NATHORST belong to the variety arctica, (J. 

 VAHL) WATS. 



Occurrence. S. Ivsugigsok (NATHORST); Inglefield Gulf: Burdin 

 Bay (INGLEFIELD), Nunatak in Verhoeff Glacier (MEEHAN), Netlik (HAYES); 

 Foulke Fjord, Etah (MEEHAN, 220, 1496); Rensselaer Harbour (KANE). 

 N. Polaris Bay (HART).

Fig. Fl. Dan. T. 130. 



Although this plant is not spread north of 70 in Danish Greenland, 

 there is still not sufficient cause for any doubt of the statement of WETH- 

 ERILL, and therefore I enter it on his authority. 1 



Occurrence. S. Netiulumi in Inglefield Gulf (WETHERILL). 



Distribution: East Greenland up to 61, West Greenland up to 

 70, Labrador, Canada, Western Arctic and Temperate America, Rocky 

 Mountains. Unalaschka, Kamshatka, East Siberia. Altai, Himalayas, Cau- 

 casus, Ural, Northern Russia, Scandinavia, mountains of Central Europe, 

 Great Britain, Faeroes, Iceland. 



1 When I wrote my Fl. Ellesm., I was not aware that WETHERILL had recorded 

 I), incana from N. W. Greenland. Taken together with this statement, the re- 

 cord of D. borealis from Grinnell Land becomes a little more probable as the 

 latter name signifies one of the forms of D. incana. It may. however, be that 

 both records ought to be in fact transferred to D. hirta.
