There can be little doubt that the specimens licrc alluded
to, belong to the species wc have denominated hrevirostru ;.
and we should perhaps be justified, upon such authority, were
we to bring the Tortula rigida of S w a r t z into the list of
our synonyms, although his specific character is not of itself
decisive.
The true Tortula rigida is that of Mr T u r n e r ,— the
Bryum rigidum of D i l l e n i u s and H u d s o n , the leaves of
which are furnished with a nerve. The Toriida rigida of
S m i t h {Barhida rigida, H e d w l ) , is again another plant,
nearer the subject of our present description, in having nerveless
leaves ; but differing from it in having those leaves of a
longer and narrower form, and in having an operculum only a
little shorter than the capsule.
