Vascular Plants of West Greenland. 375- 



Raiinnculaceae. 



81. Ranunculus lapponicus L. — In damp moss, in bogs 

 and between healh-planls; occurs in protected localities only, but 

 then usually in great abundance. Lakse Fjord as far north as 72° 30', 

 Amitsuarsuk, Proven (Нлит), Sarfarssuit and Igdlorssuit. The locali- 

 ties recorded must for the present be regarded as the northern limit 

 of the species in West Greenland. 



82. Ranunculus hyperboreus Rottb. — In bogs, especially 

 in manured spots; f. fliiitans occurs in pools. Common, but scarcely 

 as common as the following. 



83. Ranunculus pygmæus Wahl. — Very common every- 

 where in bogs and damp spots on heaths; J. Langeana Nath. is not 

 rare in manured soil or in the shade under Salices and Carices. 



84. Ranunculus nivalis L. — On rocky flats and heaths; 

 very common. 



85. Ranunculus sulphureus Soland. — In similar locahties 

 as the preceding, but scarcely as common, at any rate in the low- 

 lands. On the other hand, it is no doubt the one which occurs 

 most frequently in the mountains and on moraine material exposed 

 to the wind. 



86. Ranunculus pa ci ci stam in en s Tausch, var. era di cat us 

 (Laest.) Gelert. — In small lakes in the interior of Lakse Fjord and 

 at Amitsuarsuk as far north as 72° 30'. Even at the end of July the 

 plants were not flowering. 



Northern limit, as previously known, was 70° 25'. 



Papaveraceae. 



87. Pap a ver radicatum Rottb. — Very common among 

 scattered vegetation. 



var. albiflorum Lange. — In similar localities as the preceding. 

 Prøven, Lakse Fjord, Sarfarssuit and Igdlorssuit; rare. 



This conspicuous form which does not appear to be connected 

 with P. radicatnm by intermediate forms is no doubt hereditarily 

 constant. Here it occurred in small colonies, derived from an old 

 parent-individual, and it could easily be seen how all the younger 

 individuals had arisen where the melted snow had deposited the 

 seeds of the parent-individual. 



Cruciferae. 



88. Arabis arenicola (Richards) Gelert. — On open moraine- 

 gravel in river-deltas and on terraced slopes; not frequent. Ingnerit 

 Fjord; Svartenhuk; at Manitsogut, 71° 29', and Igdlarssuit.
