The Flora of Disko Island and Adjaccnt (loast of West Greenland. 9i> 



A Southern type; north of our area only once found at the south 

 coast of Svartenhuk at ca. 71°42' (P.), the northern limit in West 

 Greenland. 



Abundantly flowering and fruiting. 



Hibernates covered by snow. 



J. 194. Potentilla (Gomarum) palustris (L.) Scop. 



In smal, shallow pools. 



A decided southern type, only ol)served a few times in the southmost part 

 of the area: Præstefjæld at Holsteinsborg 66°56' (W. & H.; P. & E.); Sarfarssuaq 

 67°50' (P. & E.). 



At the beginning of August our specimens from Holsteinsborg 

 had even just become free from ice and would hardly be able to flower 

 that year. But the specimens from N. Strømfjord were flowering abun- 

 dantly, but we cannot say whether they were able to fructificate or 

 not, and we did not find old fruits ^. The piants were forming extensive 

 patches totally filling the pool; in another pool just in the neighboiu'- 

 hood Menyanthes^ equally rare in Greenland, predominated. 



The specimens collected by us belonged to /. ti/pica Gunnarsson,. 

 subf. subglahra Gunnarsson: Bot. Nat. 1914 p. 218—219. 



The above mentioned piaces represent the northern limit of the 

 species in Greenland; south of the area from various piaces right down 

 to the southmost of Greenland, but everywhere rare. 



Hibernates under and in ice. 



A 195. Potentilla (Sibbaldiopsis) tridentata Sol. 



In sandy and poor heath and on rocks. 



Disko: Recorded from Godhavn (Lyngmarken) by R. Brown and Hart,. 

 but, according to Simmons, the specimens belong to Sihbaldia. Also by Meehan. 

 In vain searched for by us during many years. — Behind Skansen 69°26' (P.) on 

 tertiary sandstones. 



Mainland: Atå about 69°45' (Th. P.!); from several piaces near .lakobshavn 

 Icefjord (P.). Påkitsoq fjord 69°28' in several piaces (Bg. ; P.) From Jakobshavn 

 icefjord southwards more frequent, but always far from the coast. In N. Stromfjord 

 and south hereof common. 



A southern type. The above mentioned piaces represent the 

 northern limit of the species. In South Greenland sometimes ascend- 

 ing to 6—700 m. 



Flovers abundantly, but develops hardly any fruits in the northern 

 parts of its range. 



Undoubtedly sometimes snowless during winter. 



^ In H. H. I have only seen unripe fruits on one specimen from the south- 

 most Greenland.
