 They must be regarded as female flowers. 



The style is long and the stigma has 5 protuberances 

 (Figs. 5 C; e K). 



The flowers are homogamous or very slightly protogynous ; 

 they are evidently adapted for cross-pollination by insects, but 

 self-pollination may also take place. According to Skottsberg 

 they have in Lapland a very strong perfume suggestive of that 

 of the rose.

Pollen may occur in quantities in the open anthers at 

 the same time that the stigma is viscid, and pollen may be 

 found on the stigma of flowers which have not as yet fully 

 expanded. 



The plant is chiefly propagated by seed. The capsules 

 ripen both in West and in East Greenland (Angmagsalik).
