Of this elegant and rare Northern species of Fern no figure has yet been published. The name 

 is given from the fragrant scent of the species yielding an odour, even in the dried state^ not unlike 

 that of the common Primrose. 



It is peculiarly an arctic plant; and our finest specimens, from which the accompanying figure is 

 taken, are from the island of Igloolik, where they were gathered by Captain Parry.
