bees, but insect-visitors are rare in Greenland (M. Porsild, 

 in litt.), nor are they common in Northern Norway (Ekstam, 

 1897, p. 175); from Spitzbergen humble-bees are absent (Auri- 

 viLLius). In spite of this, the species regularly sets fruit 

 everywhere; it must also be said to be the one of the Arc- 

 tic Pedicularis spp., which is best fitted for self-polhnation. 



In flowers hke E and O (less, it is true, in /) self-polli- 

 nation is inevitable. 



The seeds are described and figured in Lange, 1871 

 (tab. III, fig. 21). 



Geographical Distribution: West Greenland from 

 64° and northwards, rare between 64° and 68°; East Green- 

 land from 65° and northwards (rare in the district of Ang- 

 magsalik); Arctic North America (the continent and the 

 islands), Arctic Siberia and Russia, Nova Zembla and Spitz- 

 bergen, the mountain summits of northern Scandinavia. 



In Greenland, according to the numerous records in 

 the literature, it appears that the species makes no great 

 demands as regards the nature of its habitat. Thus it can 

 be found on heaths, mossy flåts, herb-slopes, in coppices and 

 in fissures in fields where the surface is cracked into poly- 

 gonal cakes (rudemark) (Lange, Warming, Hartz, Kruuse 

 and M. Porsild), according to the last author also in gravelly 

 barrens (1920, p. 143). In Greenland this species can dis- 

 pense with a snow-covering during wdnter, and it is there 

 a decided sun-plant, (M. Porsild), and has not its proper 

 home in the snow-troughs. 



According to Norman, in Northern Norway it prefers gra- 

 velly, not grass-covered localities, and there it has not hitherto 

 been found where the aspect is sunny, but only on the north- 

 ern and indifferent (eastern and western) sides of the mountains ; 

 it belongs there to the flora of the snow-troughs (Th. Res- 

 voll). A. Cleve also remarks: "Bedarf sehr wenig Insolation
