results and shows that the species which have the concentric 

 structure of the bundles of the leaf-stalk are found in the 

 "region montagneuse" of the Alps, while the subnival Alpine 

 species have the common collateral structure of the bundles.

As is well-known S. Murbeck^ has demonstrated par- 

 thenogeny in a whole series of Alchimilla-^^QCie^ including 

 A. alpina in which development of the embryo frequently 

 takes place even while the flower is in the bud-condition. 

 MuRBECK did not find a single pollen-grain capable of germin- 

 ation in A. alpina. Nor does A. færeensis appear to develop 

 pollen-grains capable of germination. 



In the insignificant yellowish-green, apetalous flowers 

 there is around the gynaeceum a broad fleshy disk which 

 secretes honey. H. Müller (1. с.) has described the structure 

 of the flower of A. alpina.

In Arctic Norway this collective species grows in widely 

 different localities, having been found both in dry and in 

 damp places, in open spots and in birch-woods (Norman). 

 In Greenland it grows in damp grassy fields and in willow- 

 copses. 



In my material the foflowing elementary species occurred: 

 A. aciitidens Bus., glomenilans Bus., and minor Huds. All 

 these species extend to the north of the Polar circle in Green- 

 land and Europe; they are also found in Iceland, and A. aciit- 

 idens and A. minor occur in the Færoes; they are found, in
