I have within this species classed only specimens undoubtedly 

 corresponding with Malmgren's C. alp. v. caespit., as it appears to 

 me that the limits drawn by Murbeck round G. Edmonstonii are so 

 wide that it enters into the domain of G. alpinum. Malmgren's 

 var. (G. arcticum) is on the other hand a form very characteristic 

 and easily recognizable in East Greenland, and it cannot be con- 

 founded with G. alp., at any rate not when it is seen in nature. 

 Its appearance in flats of sand and clay distinguishes this plant 

 from the above-named species that lives on rocks.

During the flowering the numerous flower-stalks are ascending, 

 hut tlien they straighten themselves fitting tightly to the held until 

 the fruit is ripe. Then they again bend upwards rising the siliques 

 4 — 6 ctm. above the ground.
