We should recollect that the Calluna advances to the extreme western 
limits (or out-liers) of Europe, in Iceland, Ireland, and the Azores. The

Without doubt these are the very specimens referred to by Mr. Don, 
then curator of the ——- Societ a And now that the stations where 
they were collected are made known, we may expect that the plant will

In view of this, and of its common occurrence in Ireland, Iceland, and 
the Azores, Dr. Seemann opines that “its extension to Newfoundiand an 
the American continent is therefore not so much a paradox as a fact at 
which we might almost have arrived by induction.” It seems to us that
