indeed are smaller than some which we have received from
the continent. Leaves few, the uppermost larger than the
rest, ovate-acuminate, concave, the points somewhat recurved
and the margins slightly reflexed, the reticulation formed of
rhomboidal pellucid areolas. Capsule reddish-brown, with a
thick blunt beak one third of its own length; it is attached to
a very short stout pedicel, and is entirely concealed by the
leaves; its walls thick, and when seen by transmitted light,
of a full yellow colour. Sporules numerous, small and very
pale. Calyptra somewhat conical, rarely cloven on one side.
From P. cuspidatum our moss is readily distinguished by
its much smaller size, and short ovate leaves. In general
aspect and size it more resembles P. muticum, from which it
is abundantly distinct.
According to Bruch and Schimper this species is dioicous;
but in our specimens naked antheridia are found in the axils
of one or two of the uppermost leaves of the fertile plant, unaccompanied
by jointed filaments.—W. W.
