MOSS NOTES.— II. TWO POGONATUMS 
A. J. Grout 
In preparing the manuscript for a new handbook on mosses I had occasion 
to study carefully our two Pogonatums with persistent protonema. The 
distinguishing characters are far more clearly cut than any published description 
would indicate. 
P. brevicaule (Brid.) Beauv. is the common species in the North with 
which all bryologists are familiar. P. brachyphyllum (Mx.) Beauv., though 
common in the South and extending as far north as Long Island, New York, is 
much less well known and doubtless often overlooked. 
In P. brevicaule the leaves are narrow, serrate, and pointed. The capsules are 
cylindric and erect, or drooping by the bending of the seta, two to six times as 
long as broad, usually straight^ The calyptra is light gray, sometimes with a 
tinge of brown. In P. brachyphyllum the leaves are tongue-shaped and entire. 
The capsules are shorter and broader, not more than twice as long as broad, and 
plainly curved. The calyptra is a tawny red-brown. 
Occasionally there are plants of P. brevicaule with capsules as short and 
broad as the larger forms of brachyphyllum but the other characters are prac- 
tically always distinct.
