Trunks of trees, England, and south of Ireland, plentiful, (Wils.):
rare in Scotland. Fr. April. Stems slightly branched, diffuse. Leaves
imbricated on every side, concave, the nerve disappearing below the
point, the margins recurved and quite entire. Perichcetial leaves as long
as the sessile oblong-ovate capsule, broadly ovate and suddenly acuminated,
almost cuspidate, having a nerve reaching to the point. 1 id conicoacuminate.
Cah/ptra mitriform, brown ; somewhat fringed at the margin.
At the suggestion of Mr. Wilson, who finds the inner peristome of D.
splachnoides to arise from a membrane as in Iloolceria, I have referred
that species to the latter Genus.
B. Inner peristome composed of cilia united beloio into a
membrane or connected by transverse bars.
37. Fontinalis. Linn. Water-Moss.
Seta lateral. Peristome double: the ou'er of 16 teeth; the
inner of 16 cilia, connected by transverse bars and forming a
reticulated cone. Calyptra mitriform. (Muse. Brit. cd. 2. t. 3.)
Named thus from its being an aquatic Genus.

Rivers and stagnant waters. Fr. June.— Stems a foot or more long,
fluitant. Leaves broadly ovate, trifarious, decidedly complicato-carinate,
rarely plane, as in a var. found by Mr. Harvey, easily splitting at the
keel. Fruit principally on the lower part of the stems. Perivhcctium
large; its leaves resembling closely imbricated scales which cover the
Capsule, and are of a roundish form, concave, nervele— , generally erose
at their apices. Capsule elliptical. Ltd conical, acute.
The specific name was given to this plant by Lhuuciis, in allusion to
the use made of it by the Swedish peasantry, who fill npwith it the
spaces between the chimney and the walla in their houses, and thus
