lidniuuulus ^lacialis whicli is a widely distiilmtrd s|it(i('s in nurtli- 

 ein and aljiine Enrojx' (also in l<eland and Jan Maven), has reached 

 only the east coast of Greeidand, where it is fonnd between ca. 77^* 

 and 66° N. Lat. 



Areruiria ciliata pseudojrigidu occurs in Greenhind only on the 

 eastern coast from Germania Land (76°4o') to 69°25' X. Lat. Outside 

 Greenland it is knnwn from Spitsber^en, Xowaja Semlja and the arctic 

 coast of Europe; thns it is in Greenland a distinctly eastern plant. 



Aretiaria ciUata norvegico (Ui the other hånd has a wide area of 

 occurrence in the northernmost j)arts of Europe inclndins: Iceland; 

 but in Gieenland it has only been foimd rather scattered on the more 

 northern part of the west coast, down to ca. 69°15' N. As to North- 

 Greenland is has hitherto only been recorded from Murchison Sound 

 (ca. 77^45' N.). In Arctic America Simmons (1906) found it in Elles- 

 mere Land (ca. 76 30' \.) and a few other records exist, viz. from La- 

 brador down to Gaspé County, Quebec. It seems to me that this sub- 

 species is more probably of western origin. I have namely in 1924 found 

 specimens of iL under other names in the Canadian National Herba- 

 rium (Ottawa), collected in several piaces of the Rocky Mountains 

 (from Kicking Horse Pass up to Yiikon). 



Carex saxatilis (C. pulla). As this species is sometimcs confused 

 with related ones, e. g. C. rolundata and C. compacta {(\ membrano- 

 ftacta), its area of distribution is not exactly known. It is common in 

 northern Eurojie in the mountainous and arctic parts, and is in Green- 

 lanrl found in a few |)laces on Imtli sides; the most ndiihein localify 

 is Wolstenholine Sound (ca. 76*^ N.). From Arctic America it is not 

 known with certainty. 



With regard to the case of Dnjas octopetaUi the matter is rather 

 com])licatedM. In Eiirope and Asia IJ. octopetala is thr imly species of 

 the genus; it is widely distributed and is e. g. also common In Iceland. 

 In IS'. America D. octopetala occnis in Rocky Mountains reachmg north- 

 wards to the arctic coast of western X. America; m eastetn \. America 

 it is also found, viz.: on the high mountains^). But nmtli- and east- 

 wards to it D. integrifolia occiu-s and is the only sjiecics found all over 

 the Arctic American Archipelago. Also in (iicejdand /). mhgrifolia is 

 a common and widely distributed sfiecies, bul towaids noitJi of Green- 

 land both species occur. On the northern east coast from ca. l(f N. 

 northwards the small-leaved form of D. octopetala (var. minor Hook.)
