Other deviations were also met with. In South Greenland 

 Mrs. Lundholm found double flowers. 



Fruit ripens abundantly in Greenland, Jan Mayen, Iceland, 

 the Færoes, Spitzbergen, Beeren Eiland, Siberia and in Arctic 

 Scandinavia. It ripens so regularly that fertilization must be 

 absolutely certain, probably by means of self-pollination.

A herb of the Pnmw/a-type ; agrees altogether fairly closely 

 with S. nivalis. The rhizome is erect or somewhat oblique ; 

 fairly thick and robust, and furnished with long, vigorous 

 adventitious roots ; it gradually dies away at the hinder end. 

 It may either be branched, or set with buds. 



Branching. The shoots may remain for several years in 

 the rosette-stage before they flower. On a flowering shoot 

 the principal lateral bud, which is situated in the axil of 

 one of the uppermost leaves of the rosette, may be so fully 

 developed while the parent shoot is flowering, that its foliage- 

 leaves principally serve to form the rosette at the base of the 

 inflorescence, the foliage-leaves of the parent shoot being for 

 the most part dead. 



The leaves are all foliage-leaves, which are often more 

 or less red. 



The flowers are small and rarely open in a stellate man- 

 ner, but remain more or less closed with small, erect or slightly 

 inwardly-bent, petals (Fig. 17). The diameter is 5 — 10 mm. 



pentandra" , the petals of which were also metamorphosed into stamens 

 (Botan. Zeitg., 1856).
