Hab. Canada. Michaux, Banks of the Saskatchawan. Dr Richardson, Drummond, Newfoundland. Mr 

 Cormach — With the habit of Z. alpinum, the species has totally different leaves and a different insertion

Hab. Canada, Michaux. Saskatchawan. Drummond, — The few specimens, gathered by Mr Drummond, 

 are all I have seen of American origin. Dr Greville and myself were unquestionably wrong in referring
