lands may be attributable to the incomplete state of our 

 information about the botany of those provinces. The 

 name is marked in the Rev. G. Gordon's List of Ross 

 plants, and also in a list of Orkney plants from the Rev. 

 C. Clouston ; so that it is possible there may really be a 

 provincial generality for tliis species. Probably ascends 

 in Scotland considerably higher than is indicated in the 

 formula ; but I have no note of observing it farther within 

 the Highlands than at the head of Loch Earn, not much 

 over 100 yards of altitude. If T. biflorum (infra) belong 

 to this species, and the alleged station of " rocks on Ben 

 Lawers " may be relied ui^on, T. caninum should be con- 

 sidered to ascend into the arctic region.
