Dr. Hornschuch has, very much to my surprise, in the work above
quoted made this a variety of the preceding moss W. Mielichoferi ; though
to me the whole habit of the plant, as well as the form of the capsule
and texture of the leaves, appear different. The greatest deference is
nevertheless, due to the opinions of so acute an observer ; and he has moreover
had the opportunity of studying the individuals on their native alps.
