The Flora of Disko Island and Adjacent Coast of West Greenland. 97 



2) var. grandis Lehm. North-east Asia, North America, especially 

 the western part, but also New Foundland and (? Greenland. 



3) var. groenlandica Ser. Arctic- and subarctic Europe, Asia 

 especially the North-East, America, Greenland. 



4) var. Egedii Wormskj. With the same distribution as the pre- 

 ceding, but in Greenland farther northwards. 



Having no access, however, to Wolf's work here, but only to 

 extracts from it, and as Lange and later authors give another classifi- 

 cation, I am only able to sketch incompletely the distribution of the 

 forms in our area. 



1) Var. Tulgaris has neverbeen seen by us nor reported from our area. 



2) Var. grandis has been reported twice : from Sånerut in N. Strøm- 



fjord 67°40' (Korn.) and from an islet in Sydost Bugt, 68°35' 

 (Htz.) By Robinson & Fernald (Gray's Manual 7th edition 

 this form is merely considered a luxuriant state (of var. vul- 

 garis?) in rich meadows. We have several times found large, 

 luxuriant forms in rich manured soil, for instance, on an 

 islet near Akiinåq, 68°35', Isuamiut, 68°42' and Ugssuit at the 

 head of N. Strømfjord, 67°50', but we do not doubt that they 

 were only overmanured specimens of vrt. Egedii growing close by. 



A 3) Of var. groenlandica Ser. I have seen vigorous specimens, col- 

 lected by Ostenfeld at Eqaluit, Ameralik-fjord, 64°10'. They 

 were determined by Kolderup Rosenvinge to the main- 

 species, but the felt is dull and not covered by silky hairs. 

 Similar specimens I possess from the island Ssolowetsk in the 

 White Sea, collected by Pohle^); and in our area we collec- 

 ted them at Itivneq near Holsteinsborg, 66°58'. 



A 4) Var. Egedii Wormskj. is declared by Robinson & Fernald, 

 (1. c.) to be a dwarf state, common on exposed rocks, whereas P. A. 

 Rydberg, the American monographer of the genus, keeps it 

 as a distinct species {Argentina Egedii (Wormskj.) Rydb. It is 

 the form best known to us. 

 y ar. Egedii (Wormskj.) occurs only near the shore, as w^ell on sandy 



or clayey as on rocky ground with scanty covering of earth, but, as a 



rule, only as high up the cliffs as they are periodically wetted by the 



surf. 



Disko: Numerous localities are known, especially on the southern, western 

 and northern coasts and in the fjords (P.). 



Hare (P.). 



Mainland: from Marraq at the outflow of the big river on Niigssuaq peninsula, 

 70°30' southwards, occurring in numerous localities, but nowhere common. 



^) from the same place and by the same coilector I have specimens of var. 

 vulgaris with silky hairs over the felt.
