Erigeron compositus (E. tri/idus), a wcstciTi species, widcly dislri- 

 buted in Greenland, also on the north roast. Not found in Arctic Eiirope.

T. fihi/matocarpiun is known from the wholr ikiiIIhiii Greenland 

 from ca. 71'^ on the east coast to ca. 70° on Ihf wcst coast; f ml her from 

 Ellesmere Land. 



T. hijparcticum is found in several piaces of Arctic North America; 

 it reaches the most northern part of Greenland (ca. 78° — 82°30' N.), 

 but not the east coast. 



T. pumiliim is only known from a few piaces in Arctic America 

 and from the north coast of Greenland, 



Pirola grandi flora is widely distributed in Greenland as far north 

 as 79° N. on tho west coast, but not on the north coast itself; it is a s|)e- 

 cial form of J*. rutiindifolia and as such not known in northern Europa, 

 where the moin species is common. 



Pedicularis arctica, a western species, in Greenland niily loiiiid 

 on Ingledeld Land (ca. 78°20'— 79° N.) of the N. W. coast. Rather 

 widely distributed in Arctic America. 



Pedicularis capitala, as P. arctica. 



\\ . The rest of the flora, viz. 85 species, have a more or less com- 

 plete circumpolar distribution, Some of them are very common arctic 

 species, othcrs occur more scattered, e. g. Eutrema Edwardsii, and 

 Erigeron u ni floms eriocephalus (the latter perha])s better ranged as a 

 western j)lant). 



As to their more or less arctic character not much can be said. 

 Some of them only reach the most southern parts of North-GrtM'ii- 

 land, e. g, Calamagrostis arundinacea piirpiirascens, Cardamine pratensis, 

 Cobresia biparlita^ Junciis castaneiis, J. trigluniis, Ranunculus trichophifl- 

 lus, Knenigia islandico and Hippuris ritlgaris, and are noth high-arctic 

 in a stricter sense; but nearly every degree of more nr less pronounced 

 arctic character can be found. 



To get an idea of which sj)ecies are ablc to live under the harde.sl 

 conditions and farthest north the hst of species from the north coast 

 gives good hints, the more so because the flora of the north coast is 

 best known, this being the only area of North-Greenland which 

 has been invostigated by a trained botanist. Now, this list includes 

 71 species (counling 5 species of Taraxacum), as may be seen from 

 the main list (tablc I); in the smaller lists of species with eastern or
