well marked in some of the characters, especially in tlie long pedicel and
tlie leaves reflexed on the borders. It differs from Braunia in the form
of the capsule, and the leaves not plicate, but papillose on the back. The
Jlediolglem, like the Cinclidotem, are cladocarpous mosses, the flowers
being terminal on short lateral branches. Mueller places them in the
JlypnacecB as species of Pilotrichum or Neckera, while Mitten refers
them to the Leucodontece.
T ribe V. ORTHOTRICIIEÆ.
Plants tufted. Stems dichotomously fastigiate by innovations,
short and erect, or long, creeping and decumbent with
short erect flowering branchlets. Leaves equal except at the
base of the innovations, reflexed or squarrose when moist, sub-
imbricate or cirrate-crispate when dry, terete-costate, opaque,
minutely papillose; areolation minute, punctiform, chlorophyllose
in the upper part, hyaline, longer and narrow or
rectangular-hexagonal in the lower. Calyptra mitriform, subcylindrical,
furrowed or plicate, generally hairy (inflated and
cucullate in Amphoridium and Drummondia). Capsule on an
erect pedicel, immersed or emergent, symmetrical, erect, often
striate. Lid straight-beaked. Peristome simple or double,
rarely none, the outer of 8 higeminate broadly lanceolate teeth,
or of 16 geminate flat teeth distantly articulate (bifid to the
base in Ptychomitrium) ; the inner of 8 or 16 free cilia.
5 0 . COSCINODON, Sprengel. (PI. 4.)
Leaves piliferous, loosely reticulate at base, not crispate.
Calyptra covering the capsule to the base or to the middle.
Lid very large. Teeth of the peristome broadly lanceolate, distantly
articulate, generally very cribrose, rarely entire, granulose,
dark purple.

obovate, concave, spoon-shaped, erose-denticulate from below
the apex, rapidly narrowed to a serrate hair-point twice as long
as the leaf and formed by the stout excurrent costa; basilar
areolation loose, pellucid, oblong, that of « « upper part
smaller and oblong-oval, chlorophyllose m the middle, pellucid
toward the apex : flowers monoecious, the male on terminal
branchlets: calyptra descending to below the middle tlie

curved pedicel, erect, oval-oblong, truncate at base, thin, smooth
when dry; lid conical, rostellate; teeth purple, lanceolate,

8. 0 . R au i. Plants cespitóse, dirty green: leaves obovate,
loosely imbricate or spatulate, rapidly acuminate into a somewhat
long denticulate pellucid hair-point, plane and entire on
the borders; costa stout, vanishing below the slightly erose-
dentate apex: flowers monoecious, the male in separate axillary
buds near the base of the perichætial leaves : calyptra large,
plicate, covering the capsule to the middle : capsule oblong-
oval, rounded or subtruncate at base, thin ; lid with a broad
conical beak ; teeth lanceolate, acuminate at the apex, entme,
split merely or perforated here and there on the line of division,
erect when moist, open when dry; annulus broad, persistent.—
