rather than C. radicans Forst, the character- 

 istic root-leaves of which were sought in vain. 

 I thought that it might be the C. palustris, 

 var. radicans of Fries, which has been said 

 not to be the true plant of Forster ; and Dr 

 Lange to whom I sent it, together with 

 root-leaves of C. radicans, Forst. (from Mr 

 A. Bennett's garden) for comparison, replies 

 that Fries's plant from Finmark appears to be 

 the same as mine, which may possibly be a 

 distinct species." 



Beeby in Scot. Nat. 1887 adds further: 

 " This plant seems to pass gradually from 

 forms in which the leaves are roundish and 

 almost entire, into forms which can scarcely 

 be separated from C. radicans. On the other 

 hand I found this year by the upper end of 

 Loch of Cliff large erect forms of C. palustris 

 which did not root at the nodes of the flower- 

 stems, but in which the leaves were exactly 

 similar to those of C. radicans ; thus 

 palustris and radicans both seem variable in 

 their leaf-forms and in the size of the flowers, 

 and I am disposed to think that the 

 rooting stems afford the only reliable char- 

 acter for the separation of the two plants ; 

 hence I believe that zetlandica should be
