This fine Tortula has, like T. convoluta and T. revoluta, the 
perichetial leaves differing remarkably from the rest in figure, 
and sheathing the base of the fruitstalk. With the last-men- 
tioned species, too, it agrees in having leaves with revolute mar- 
gins ; but here, besides the much larger and branched stems of 
the plant, the leaves have a long hairlike point, which is a con- 
tinuation of the nerve.
