As Nathorst (Nya bidr.) and Gelert (1. c.) have pointed out, D. 

 psilosantha cannot be separated from D. Fisheri. My specimens agree 

 most with the descriptions of the former. I first found this plant im- 

 mediately before our departure from the Goose Fjord, and was only 

 able to snatch a few straws of it on my way to the boat. It seems 

 probable that it flowers rarely, and has not therefore been observed, 

 either in other localities, or where it was then found, in wet mossy 

 places below the Falcon Cliff, a locality which I had visited previously 

 several times. I am very much inclined to think that I saw it also in 

 the rich vegetation of the large valley on the West side of the Walrus 

 Fjord, which, however, was passed in a forced march only, a fact which 

 is the more regrettable, as there would probably have been much 

 of interest to find. In other arctic tracts, especially in Greenland, the 

 plant is rare and sporadically appearing. 



Occurrence. South coast: Goose Fjord, below Falcon Cliff (4236). 



Distribution: Northern Danish West Greenland, Arctic Ame- 

 rican Archipelago (specimens seen from Baffin Land and the original 

 ones from Melville Island), Arctic America, Labrador, Hudson Bay 

 region, Alaska, Pribilof Islands, St. Lawrence Island, Land of the 

 Chukches, Arctic Siberia, Arctic Russia, Novaja Semlja, Spitsbergen, 

 Franz Joseph Land.

Lange, 1. c, p. 173, has explained why the name of Vahl is to be 

 used for this plant instead of that of Smith, notwithstanding the fact 

 that the former has reference originally to one form only of the many
