This species also is rather difficult to define; many species have 

 been established within the range of its form-series, as is to be seen 

 in the synonymic and further in the paper of Gelert quoted above. I 

 can fully accept his views except in one instance, viz., when he puts 

 D. altaica, Bunge, under it as a variety. I shall have to speak more 

 about that plant later. 



In the flowering slate, even dried specimens are generally rather 

 easily distinguished, at least if they are in not too bad a state of pre- 

 servation. But in its fruiting state, its resemblance to D. alpina can 

 be so great as to make it very difficult to decide upon the place of a 

 dried specimen, sometimes also of a living one. The variety D. alpina 8 

 of Hooker, 1. c. I, p. 50, which is said to have white flowers, probably 

 belongs to D. fladnisensis ; perhaps also he has taken specimens of D, 

 alpina with old, withered, and whitish petals for a white-flowered variety, 

 but I have never seen any D. alpina with white flowers. The forms 

 of D. alpina that are most easily confounded with D. fladnisensis, are 

 especially the more slender ones, such as the var, gracilescens. The 

 shape of the leaves as also the hair-covering vary, just in the same 

 manner as in D. alpina, only the colour of the petals gives a distinct 

 character, all others are relative. Indeed, the different sorts of hairs, 

 especially the forked and stellate ones, are as .'a rule somewhat different 

 in J), alpina and J), fladnisensis, but their forms are not constant,
