Ejland and Maneriniiil ()8°35'; in vain scardied for in these piaces by Kruuse' 

 and us. 



A northern type, the above-nieniionerl piaces represent the 

 soiithern limit. 



Abundantly flowering and fruitinjj-. 

 Hibernates covered by snow. 



I 154. Ranunculus hyperboreus Rottb. 



In inoist piaces, for instance, in moss at the springs, in small pools^ 

 often in manured soil. 



f. fluitans ! (Syn. R. aquatUis var. arcticiis Durand PI. Kan. No. 1. 

 Appendix to E. K. Kane: Arctic Explorations The Second Grinnell 

 Exp. in search of Sir John Franklin 1853, 54°o5', Philadelphia 1856 

 vol. II). 



In small sheltered and manured pools at the settlements a lux- 

 uriant form occurs with lengthened petioles, and floating leaves of extra- 

 ordinary size. Most frequently the whole surface is covered by them. — 



Most frequently quite sterile, but sometimes flowering at the mar- 

 gins of the patches as the water gradually dries up. 



I do not doubt of the identity of the plant collected by Kane and 

 determined by Durand, with the above mentioned variety, though the 

 flowers are recorded white. The petals of various Ranunculus-species, 

 especially those of R. hyperboreus and nivalis, often become white during 

 the drying, especially when the specimens are laid in the press in wet 

 condition. 



Disko: Very comnion, h'om the coast ascending to considerable altitudes. 



Hare (P.). 



Mainland: Nugssuaq peninsula and the land east of Disko-Bay, common. 

 Rather common in the archipelago of Egedesminde; scarce, alpine or absent in the 

 fjords. Thus \ve l'ound it common at Taseralik at the mouth of N. Strømfjord, but 

 absent in the inner part, not even ascended. Also known from several piaces near 

 Holsteinsborg. 



Widely distributed in Greenland, without northern limit. 



Also known right down to southmost Greenland, but scarce and 

 seems here limited to the outer islets (Ros.). 



With the exception of the water-form commonly flowering and 

 f ruiting. 



Hibernates covered by snow and often by ice. 



A 155. Ranunculus lapponicus L. 



In nioist moss-bogs in the lowland favourably exposed lo the sun 

 during the summer.
