the argument that Dr. integrijolia was only a variety of Dr. octopetata. 

 This argument must, however, be discarded, because the var. integrifolia 

 is merely an ecological form (The same view has been suggested by Sim- 

 MONsr Ellesmereland, p. 45). Piants with leaves larger than usual, 

 with not revolute margins and better developed leaf-teeth occur in 

 well watered and somewhat shaded localities. But the finest specimens 

 are to be met with on gravelly banks in river beds. Narrow-leaved high- 

 land forms are often washed down and anchored here. The new shoots 

 developed in this habitat are quite difYerent: they represent the typical 

 intermedia-iorm.. Also the flowers developed under such favourable cir- 

 cumstances will hardly differ in size from Dr. octopetala (see figure). 



On the poorest and dryest tertiary sandstones occur forms extreme 

 in the opposite direction : the leaves are strongly revolute, linear, nearly 

 ericoid. 



Very different and without any transitions to the main-species 

 is the var. canescens Simm., of which I have published a figure Medd. 

 om Grl. 50, p. 379, fig. 13. It is very rare. In our area we only observed 

 it in Valleys to the head of Nordfjord on Disko 69°55' and at Marraq 

 near the mouth of the big river of Nugssuaq peninsula 70°30'. The very 

 few records, previously known, are all north of our area, and this variety 

 may perhaps be considered a high-arctic type. 



A 205. Alchimilla alpina L, 



In herb-mats and on luxuriant slopes. 



Disko: Near Godhavn (?) (Tarr. & Martin); in Blæsedalen (Th. H.), during 

 many years searched for by us, but in vain. 



Mainland:N.Isortoq67°15'(Ros.);PræstefjældetnearHolsteinsborg(W.&H.); 

 P. &E.); Amerdloq about 66°66' (W. & H.). 



A decided northern type; the above mentioned localities represent 

 the northern limit in West Greenland. Common south of 64° (Ros.). 



Our specimens were not flowering Aug. 6. 1914 (an unfavourable 

 summer), but the specimens had fruits from the preceding year. 



Hibernates covered by snow. 



yV 206. Alchimilla glomerulans Buser. 



In vigorous herb-mats on, Disko preferably at the hot springs and 

 their outlets. 



Disko: The south-land from Mudderbugt to Blaafjæld in all suitable piaces. 

 In the Valleys as well. Diskofjord: common at the hot springs and in a few other 

 piaces. Mellemfjord: in a few piaces on the north side of the fjord, at Sarqardlit 

 silardlit and Ikorfarssuit ca. 69°45'. On the west coast in N. Laxebugt 69^35' and 69°42'. 



Mainland: Jakobshavn 69°13' (W. & H.); Kangerdluarssuk at Agto (E. P.) 

 67°55'; N. Strømfjord 67°40' (Korn.); S. Kangerdluarssuk, ca. 67° (W. & H.), in 

 the fjords east of Holsteinsborg from several piaces, but not as common as on South- 

 Disko (many coUectors).
