Everywhere in arctic regions this species has an inclination 

 to get concave leaves, which are smaller and with shorter lobes. 

 The colour is commonly more or less red-brown and dark, the 

 leaf-cells and the cuticular-cells of the stem are shorter. There 

 exists howewer a gradual transition between these forms and the 

 main-species.

This species varies in the same manner as Cephalozia bicuspi- 

 data, but apparently in still higher degree. Probably one or other 

 undescribed species is hidden amongst all these more or less 

 disagreeing forms.
