The author remarks " that this fine species differs from M. 

 affine, Bland, in its longer and narrower leaves, which are 

 widely decurrent at their base, the leaves in M. affine being nar- 

 rowed to a base not wider than the stem, and not at all decur- 

 rent." The first assertion concerning the size of the leaves, 

 which are proportionally longer and narrower, is quite correct ; 

 but in Mnium affine the leaves are always more or less decurrent. 

 It is therefore difficult to consider this form as a distinct species, 

 and to separate it from tlie very variable Mnium affine.
