Among the Bartramia hitherto discovered, it would bedifficult 
to say to which the present one approaches the nearest :—per- 
haps to B. patens of Schwaegrichen (B. squarrosa of Turner) ; 
but that species has the leaves remarkably straight, and neither 
that nor any other which I am acquainted with has a capsule at 
all like the one here figured.
