* I am satisfied that varieties of two different plants pass under this 

 name, the one being Potentilla reptans, the other Tormentilla offici- 

 nalis. Whether there does exist a third species, distinct from both, I 

 am unable to say. Eriophorum polystachion, in like manner, is re- 

 presented, one while by E. angustifolium, at another by E. pubescens. 

 Nor are these the only examples of British plants thus crossed.
