Plants loosely casspitose.
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; at 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, at the base of the
fruit-stalks, expanded in the form of a ro se ; 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
areolse of the reticulation are small.
Perich®tial leaves much smaller than the rest and
more acute, having the margins scarcely incras-
sated.
Female fructification terminal.
Fruit-stalks generally many together, an inch long or
more, below croceous, above yellow, shining, erect
or slightly flexuose, at the extremity arcuate.
Capsule nodding, ovate or oblongo-ovate, in the young
ones pale-yellow brown, with the mouth red, in
a more advanced state croceous.
Operculum hemispherical approaching to convex,
fulvous, at the apex somewhat mammillate, croceous.
Calyptra pale-brown, cleft on one side.
Elastic ring none.
Peristome double: the exterior of sixteen acute, up-
right, yellowish teeth, transversely striated : the
interior a reticulated orange-coloured membrane,
unequally laciniated ; having the greater lacinias,
sixteen in number, perforated, and the intermediate
ones two or three together, filiform, unconnected.
