1898-1902. No. 2.] VASCULAR PLANTS OF ELLESMERELAND. 95 



Distribution: All over the Arctic Regions and further in the 

 Rocky Mountains, Alaska, Islands of the Bering Sea, Kamshatka, Baical 

 Mountains, Altai, Ural, Scandinavian mountains, Scotland, Ireland, 

 Faeroes, Iceland. 



Drab a borealis, DC. 



This species is recorded by Greely, Rep. The plant of Decandolle, 

 Systema II, p. 342, Gelert, rightly as far as I can judge, reduces to 

 D. incana, L. But as that plant again is not found north of the 

 Disco region in Greenland, and nowhere north of the continental coast 

 of America, I think that the plant cannot be any form of D. incana, 

 but perhaps a D. hirta. 



Lesqiierella arctica, (Wormskj.) Watson.

Fig. Fl. Dan., T. 1520. 



This species is rare in those parts of Ellesmereland that I visited, 

 except perhaps in the interior of Hayes Sound, where I had no occasion 

 to make collections during the best season. It was found in open clay 

 fields with sparse vegetation. Greely also speaks of it as doing best 

 on stiff clay. It was found in bloom by him already on June 13, 

 1883. In September 1898, I saw it with ripe pods, but also with a few 

 flowers left. 



Occurrence. Grinnell Land: Discovery Harbour (Hart! Greely), 

 Bellot Island (Hart). Hayes Sound: (leg. Feilden!), abundant in the 

 innermost part of Beitstad Fjord (489), and also at „Fort Juliane" 

 (672), a few specimens at the front of the Twin Glacier (877), and at 

 the mouth of Flagler Fjord (891). South coast: Fram Fjord (1672, a 

 single plant found); Barren Vallies in the Harbour Fjord (2401); Muskox 

 Fjord, interior part (2150). 



Distribution: Northern parts of Greenland, Arctic American 

 Archipelago, Arctic America, Rocky Mountains. According to Hooker, 

 1. c. I, p. 48, also at Cordova in South America; and besides a variety 

 occurs on Anticosti Island (Britton & Brown, 1. c. II, p. 138).
