Gen . Char. Peristomium duplex, (dentibus rectis) int. membranaceo-laciniatum, laciniis inæqualibus. Seta
termmali. (Bryum, Mnium Linn. Hedw. Hypnum, seta terminali, Mohr. Mnium, P . de Beauv.)
Plantæ laxe cæspitosæ.
Caules repentes, ramosi ; ramis bi- tri-pollicaribus ; fer-
tilibus ereçtis ad apiçem proliferis; sterilibus
sæpissime decumbentibus attenuatis simplicibus,
vel, ut in fertilibus, innovationibus curvatis in-
structis; basi, uti in caulibus, radicibus tomen-
tosis castaneis dense obsiti. Color fuscus, juni-
oribus flavo-vireseens.
Folia undique paten tia, laxa, semiunciam fere lönga,
inferne distantia, superne circa setas in rosam ex- j
pansa; omnia ligulata, transversim undulata,
sæpe recurva, marginata, per totam fere longitu-
dinem serrata, apiculataque ; nervo excurrente.
Innovationum folia magis distantia, ovata, marginata
atque serrata. Color obscure viridis, juni-
oribus pallidioribus. Textura rigidiuscula, reti-
culationis areolis minutis.
Folia perichffitialia reliquis mul to minora, magis acuta,
, marginibus vix incrassatis.
Froctificatio feemiuea terminalis.

P lants loosely c®spitose!
Stems creeping, branched; with branches two or three
inches long ; the fertile ones, erect, proliferous at
the extremity; the sterile ones most frequently
decumbent, attenuate, simple, or as in the fertile
ones beset with curved innovations; a t the base,
as in the stems; thickly covered with downy cas-
taneous roots. Colour brown, yellow-green in
the younger stems,
Leaves on every side patent, lax, nearly half an inch
long, below distant; above, a t the base of the
fruit-stalks, expanded in the form o f a rose ; all
of them ligulate, transversely undulate, often recurved,
marginated, nearly throughout the whole
length serrate, apiculate, with an excurrent nerve.
The leaves on the innovations are more distant’
and more ovate, marginated and serrated. The
colour is an obscure green, paler in the younger
ones. The texture is somewhat rigid, and the
areol® of thé reticulation are small.
P erichjetial leaves much smaller than the rest and
more acute, having the margins scarcely incras-
sated.
Female fructification terminal.
Fru it-stalks generally many together, an inch long or
more, below croceous, above yellow, shining, erect
or slightly flex-uose, a t the extremity arcuate.
Capsule nodding, ovate or oblongo-ovate, in theyoun«*
ones pale-yellow brown, with the mouth red, in
a more advanced state croceous.
Operculum hemispherical approaching to convex,
fulvous; a t the apex somewhat mammillate, croceous.

Calyptra pale-brown, cleft on one side.
E lastic ring none.
Peristome double: the exterior of sixteen acute, up-
riglit, yellowish teeth, transversely striated : the
interior a reticulated orange-coloured membrane,
unequally laciniated ; having the greater laCini®,
sixteen in number, perforated, and the intermediate
ones two or three together, filiform, Unconnected.
