Besides Ihe principal form the curious sterile glabrous, small- 

 leaved, densely cæspitose form which Simmons (Sec. Arc. Exp. Fram 

 1898—1902, No. 2, 1906, p. 122) has named f. piilvinata Simm., and 

 which has erroneously been taken for С Edmondstonii, var. caespito- 

 sum Malmgr. (cf. Kruuse. 1. с, p. 159) was found around Danmarks Havn.

Note. In low-lying, humid soil it occurs as large tufts with decumbent 

 flowering stems, pressed close to the ground. When the flowering plant in 

 the autumn is suddenly covered with snow which remains during the winter, 

 all the parts of it are so well preserved, that in the spring when the snow^ 

 has melted, they appear again and apparently are as fresh as if they had 

 quite recently unfolded themselves. 



Ranunculaceae.

Note. Around small ponds where the snow has melted early, it is one 

 of the spring flowers. On the other hand, where the snow-drifts are peren- 

 nial and irrigate the lower-lying, evenl}^ sloping ground, it follows the drifts 

 as they melt and flowers here till the frost begins towards the end of August 

 or in the beginning of September.

The Expedition has brought home very rich material of this 

 species, while R. nivalis L., which has been recorded as far north 

 as Little Pendulum Isl., is completely absent from the collection.
