resemble each other so closely that it is difficult to separate them 
but that there seemed to be little doubt that of the 8 species 
listed for N. A. only 4 could be clearly distinguished. 
The Dicranaceae including 33 genera and 204 species have 
been arranged for the sake of convenience in the aa of 
Engler and Prantl Pflanzenfamilien, though a few changes and 
additions have been recorded; notably the addition . Pringleella 
rom Mexico. This family has required a great deal of critical 
and will be prepared to print drawings of many of these should 
it become desirable. 
When printed, this part will include 5 families, 38 genera and 
269 species as at present recorded.
