1 00 CARYOPHYLLEiE. [Aremria, 



from Greenland and from Kamtschatka, which differ in no respect from those in Capt. Beechey's collection. 

 The plant is still slenderer than A, propinqua. As is the case with that species, Chamisso and Schlechtendal 

 notice two vars., the one glabrous, the other pubescent.
