pistil. During rain the flowers maybe filled with water. But judging 

 from MQller's figure, the anthers in the Greenland and the 

 Scandinavian specimens appear on the whole to stand closer 

 to the pistil than in the Alpine specimens; sometimes even 

 they are in direct contact with it (Fig. 9 A); the stamens are 

 more erect than those in the plants from Central Europe, or 

 they may even be curved inward; so that spontaneous self-pol- 

 lination is inevitable. Lindman also mentions movements of varia- 

 tion and self-pollination, but Ekstam did not observe any such 

 movements, he even refers it to "Alpenpflanzen bei denen 

 immer die Narben mit dem Blütenstäube der eigenen Staub- 

 beutel bestreuet auftraten." 



In Greenland, honey is secreted abundantly by the ring- 

 shaped, lobed nectary at the base of the ovary (Fig. 8^). 



In Greenland I have seen small flies in the flowers; "at 

 the top, near the region of snow" Wormskiold observed a 

 butterfly sucking at one of the flowers, so cross-pollination 

 appears sometimes to take place. 



The fruit ripens in East and West Greenland and in Fin- 

 mark. But the fruit formed does not always ripen the year 

 the plant flowers, in which case it appears to perish. After 

 the corolla has fallen off" the calyx closes round the ovary.

 prostrate and produce slender roots, generally few in number; 

 according to Haglcnd Ihey occur abundantly on damp soil.
