Insula Unalaschka. Hb. L. (Syn. Hep. p. 76). 



Obs. This has been usually considered as a variety of the previous 

 species, but Prof. Lindberg regards it as quite distinct, with which 

 opinion I agree ; its neater habit, the direction of the postical lobe 

 being more horizontal than in Diplophyllum albicans, and the absence 

 of the false nerve, although traces of elongated cells near to the base 

 are sometimes observable, sustain this view.
