Differs from European specimens of D. hiixjlrosfrr col-

 teeth split only to the middl(\ more united than figured in 

 the Bryologia Europea, Table NX. It may be distinguished 

 from Cniiipylopux Vini'micn^, also remarkal)le for its catlucous 

 leaves, by tlie longer, more slender subulate j)oint, which is 

 entire or minutely serrate and smooth on the back, by the 

 thick base, witli inflcxed blades, and by the shape o|' the 

 basal cells at the angles.
