1898-1902. No. 2.] VASCULAR PLANT S OF ELLESMERELAND. 43 



guished by Decandolle (1. c.) as well as by Engler in Engler & Prantl, 

 Pflanzenfam. Ill, 5. This also is originally separated from E. nigrum 

 and described as E. purpureum by Rafinesque, in his "New Flora of 

 N. America", etc., which, however, I have had no opportunity of seeing, 

 but as it seems according to be above-quoted works to differ from the 

 type only in its red drupes and in a somewhat smaller stature and 

 thicker-set leaves, there can be no doubt that this is our plant, which 

 consequently is to be called E. nigrum, L. var. purpureum, (Rafin.) DC. 



However, I cannot assert that all Ellesmereland specimens have 

 red drupes; it is possible, that black-fruited forms also grow there, 

 moreover, as I have seen specimens with black drupes, not bigger than 

 those of my specimens, from other high arctic localities. It is curious 

 that red-fruited forms appear to be lacking in Danish Greenland, where 

 the species is very common, the more so as the appearance of red 

 drupes seems to stand in some connection with the climate, as may be 

 inferred from their re-appearance in the far south. 



Occurrence. East coast: along Buchanan Strait, at Twin Glacier 

 Valley (850), Cape Viele (883), and Lastraea Valley; Cape Sabine (Bed- 

 ford Pim Island) according to Hart. 



Distribution: The variety, according to Decandolle, 1. c, seems 

 to have been found only in Labrador, New Foundland and in N. W. 

 Greenland. The common form is distributed all over the arctic and 

 temperate regions, as well as in Europe and Asia as in North America.

I have not tried to insert in the above list of synonyms, all state- 

 ments in the literature about D. octopetala, such as should rightly be 

 transferred to D. integrifolia, as I have not always seen the specimens 

 on which the statement is based, but it may be asserted that all ac- 

 counts about D. octopetala from western Greenland and the Arctic
