The Flora of Disko Island and Adjacent Coast of West Greenland. 79 
Bjland and Manermiut 68°35’; in vain searched for in these places by Kruuse 
and us. 
A northern type, the above-mentioned places represent the 
southern limit. 
Abundantly flowering and fruiting. 
Hibernates covered by snow. 
154. Ranunculus hyperboreus Rorrs. 
In moist places, for instance, in moss at the springs, in small pools, 
often in manured soil. 
f. fluitans! (Syn. R. aguatilis var. arcticus Durand Pl. Kan. No. 1. 
Appendix to E. K. Kane: Aretic Explorations The Second Grinnell 
Exp. in search of Sir John Franklin 1853, 54°55’, Philadelphia 1856 
vol. II). 
In small sheltered and manured pools at the settlements a lux- 
uriant form oceurs 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. 
| do not doubt of the identity of the plant collected by Kane and 
determined by Durann, with the above mentioned variety, though the 
flowers are recorded white. The petals of various Ranunculus-species, 
especially those of A. hyperboreus and nivalis, often become white during 
the drying, especially when the specimens are laid in the press in wet 
condition. 
Disko; Very common, from the coast ascending to considerable altitudes. 
Hare © (P.). 
Mainland: Nigssuaq peninsula and the land east of Disko-Bay, common. 
Rather common in the archipelago of Egedesminde; scarce, alpine or absent in the 
fjords. Thus we found it common at Taseralik at the mouth of N. Stromfjord, but 
absent in the inner part, not even ascended, Also known from several places 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 
fruiting. 
Hibernates covered by snow and often by ice. 
A 155. Ranunculus lapponicus |. 
In moist moss-bogs in the lowland favourably exposed to the sun 
during the summer.
