section one half up showing one row of large cells on upper side 
with a narrow band of small, thick-walled cells beneath ; leaf-cells 
above, elongated, more or less rectangular, in margin below nar- 
rowly linear, forming a somewhat distinct border, becoming wider 
toward the costa, and across leaf-base wide and hyaline, forming a 
more or less distinct group ; perichaetial leaves, about the length 
of upper stem-leaves, with ovate-oblong, sheathing base rather 
abruptly narrowed to a rough subula about the length of sheath- 
ing part; seta erect, twisted above, up to 2 cm. long ; capsule, 
without stomata and annulus, erect, oblong, smooth, without lid
