A plant of wide distribution, and as usual with such, subject to considerable
variation ; it may however be generally recognized by the obtuse apiculate
leaves with recurved margins, and thin-walled oblong capsule without
any annulus. In its very slender fragile peristome it resembles B . fallax.

This was misplaced under Tortula at p. 218, its most natural position is
here next to B. unguiculata, and indeed it clearly forms a connecting link
between that species and Cinclidotus.

The Rev. J. Fergusson informs me that this species certainly occurs in
Scotland, but as he has not favoured me with specimens, I have made the
drawing from a Norwegian one.
It deviates from our other species of this section by the shortness of the
tubular base of peristome, but stands next to another Norwegian species,
T. Laureri ( S c h u l t z ) , and also comes near to T. (Desmatodon) latifolia ( H e d w .)
and T. systylia ( B r , S c h .).

I have preferred this name to the older one, Sekra of Adanson, as apart
from its barbarous sound, the character assigned to it would not be sufficient
to identify it ; the Linnean specific name also is in relation to Fontinalis
antipyrctica, with which the present has no affinity.
