Plants growing crowded together, thickly casspitose.
Root small, between tomentose and fibrillose, brown.
Stem scarcely any.
L eaves collected together in a rose-like head, few, small,
subpatent or often recurved, the inferior ones li-
gulate, the superior linear-oblong, in both obtuse,
undulate, a little carinate, with the margin altogether
entire, furnished with a strong distinct
nerve of the same colour as the leaf, and disappearing
a little below the apex; when dry crisped.
The substance is rather thick, opaque; the colour
obscure yellow-green.
Perich2ETIal Leaves, as Dillenius has well observed,
resembling the glumes of grasses, large for so
small a plant, numerous, erect, exceeding the
length of the capsule, and almost .covering it, ob-
longo-lanceolate, acuminate, a little convex, towards
the apex having the margin remarkably la-
ciniate or father lacerate; it has a strong, rigid, •
brown nerve, much exceeding the length of the
leaf, and is there serrulate. The substance of
these leaves is rigid, yet membranaceous; the
colour yellow-brown.
Fructification dioicous. (Hedw.)
Male discoid, terminal. (Hedw.)
Anthers minute, cylindrical, intermixed with short
articulated filaments.
Fem. terminal.
Fruit-Stalk very short, cylindrical, smooth, pale, immersed
in the leafy pericheetium, and producing
at the base a few pistils!
Capsule covered on all sides with perichastial leaves,
of the size of a grain of Hemp, ovate, oblique,
above a little depressed, but towards the base
gibbose, beneath ventricose. Substance, even in
a ripe state, soft; the colour yellowish, on one
side reddish.
Calyptra entire, mitneform, pale brown, conical, at
the apex lengthened out into a rather long, deep
brown point.
Operculum conical, acuminate, straight, reddish brown.'
Peristome simple, delicate, membranaceous, white,
forming a plicate CQne, striated: when dry somewhat
twisted.
Seeds minute, yellow-brown.
