The peristome is best seen through the hd of the young caps., but can
seldom be found at maturity, or can only be observed in small fragments
under the pressure of a covering glass. It also differs from the last by the
long seta, cylindric capsule and oblique beaked lid.
B. Aloidese. Leaves obtuse, concave with involute margins, nerve very
broad, covered on upper side with granulose filaments.

The little group of aloid Tortulæ are very closely allied, and transverse
sections of their leaves will be found useful in their discrimination. There is
considerable difficulty in fixing on the species intended by some of the early
authors, and the name rigida has been applied to all four, but, thanks to
Lindberg’s research, we are able to get rid of it altogether, and adopt prior
names.
T. brevirostris may be immediately recognized by its short lid and
synoicous inflorescence, and to Mr. Holmes’s acuteness we owe the verification
of the original specimens with the species intended by the founders.
