My dear Mr. Sewmftn:- 
I have placed the specimen you sent 
with my Polytrichum perigoniale, not that it is exactly 
what I call typical material but because it seems nearer 
that than either commune, or its var. uliginosum. 
In the absence of fruit I cannot feel as certain as I 
might if itfe were present. It may be nearer P. commune 
than perigoniale, but I thik not judging from the cross 
section of the leaf. 5?he var. uliginosum is, in its 
typical form quite different looking from your specimen, 
as you will see from a hasty sketch (diagramattie) at 
the margin og this sheet, showing the position of the 
leaves in typical material. 
I expect Mr. Chamberlain will be here at my house a week 
from today, for a brief visit. 
fery truly yours,
