Carex gynocrates. 



— pratensis. 

 Calaniagrostis confinis. 

 Deschampsia arctica. 



Deschampsia pumila. 

 Tofieldia coccinea. 

 Orchis rotundifolia. 



Similarly, we may consider the species in Groups E 

 and F as originating from the east (from Europe). 



Group E (species found in Europe but not in America), 

 contains 32 species: 



N. Leontodon autuinnalis. 

 Taraxacum brachyceras. 

 Thymus serpyllum var. 

 Veronica fruticans. 

 Utricularia ochroleuca. 

 Carex atrata. 

 — holostoma. 



N. Betula pubescens. 



Arenaria ciliata pseudofri- 



gida. 

 N. Stellaria media. 



Sedum acre. 

 — annuum. 

 N. Capsella bursa pastoris. 

 N. Geranium silvaticum. 

 N. Rumex acetosa. 

 N. — domesticus. 



Ranunculus acer. 



— glacialis. 



Alchimilla aeutidens. 

 N. Rubus saxatilis. 



Archangelica officinalis. 

 X. Viola canina s. 1. 



Hieracium alpinum. 



Of these 32, at least 15 were introduced by the Norse- 

 men (N.) and should thus also for this reason be reckoned 

 as immigrants from the east. Most of the others are also 

 subarctic and boreal species, only a few, such as Arenaria 

 pseudofrigida and Ranunculus glacialis, being arctic, 



The little F group consists of 4 species, nol found 

 on the continent of Europe, but occurring on the arctic 

 istands north of Europe ; they must presumably have made 

 their way into Greenland from the north-east:
