Hab. Newfoundland. Miss Brenton, Throughout Canada, from Lake Huron to the Saskatchawan, and 

 Hudson's Bay, abundant, N. W. America, about Fort Vancouver. Douglas, Tolmie, Dr Scolder-— 9>- 

 Canada. Cleghorn, — I fear that this, which is a very common and highly variable plant, especially as regards 

 its lax or dense growth, and size of the flowers and bracteas, and the breadth of the leaves, is only a luxuri- 

 ant state of P. hyperhorea, to which Dr Richardson has rightly referred his more northern plant. It seems 

 probable also that P, Konigii and P. Huronensis are too nearly allied to it.
