Common as this beautiful moss is with us, it is utterly unknown on the 

 continent, with the exception of a few stations m Norway, and has thus led 

 to great confusion in the synonymy of the older authors. In the Linnean 

 herbarium it is represented by A. petrophila, and in Sweden by A. obovata, a 

 species having leaves gradually lanceolate in the upper half, the basal 

 margin quite entire, and the apical cells much larger and more angular.

This marked variety has a strong superficial resemblance to A . Haytmani, 

 but is readily distinguished by its more acute leaves, and much more minute 

 areolation.
