My dear Miss Carr:- 
I have not yet had chance to go over yon mosses 
that You sent me in Mgry 1910 critically, so I cannot say with certainty 
as to just what I should call the several forms that you sent me of 
the Polytriehum commune group as®. I am quite sure, however, that 
none of them is typical P. commune . I am also quite sure that nearly oJUL 
of the c omm une forma that you sent are the var. perigoniale . As I 
recall the specimens there are two tall ones (perhaps three) that 
look, off hand, as if they might he something a little different. 
I had hoped to have time to study them "before this. Will report later.
