the cells chlorophyllose; male plants generally in separate
tufts, the comal leaves shorter and broader, spreading star-like :
capsule single or two or three in the same periohætium, pendent
on a long solid dark purple pedicel, oblong-conical, slightly
incurved, rarely obovate-oblong, not constricted under the orifice

inner membrane orange-colored ; segments lacunose along the
keel ; annulus revoluble. — Spicil. FI. Lips. 84 ; Bryol. Eur.

Ha e . Shaded pine woods, base of trees, on shaded rocks covered with
humus; not rare on the Eastern slope. Found also in California by Bolander.
The most beautiful speeies of the genus, like a Mnium in appearance,
but closely allied to B. capillare in its characters.
42. B. c o n c in n a tum . Spruce. Dioecious : plants small,
cespitose, cohering by radicles below ; stem about 2 c.m. long,
erect, julaceous, slender, filiform from the base, reddish below,
green above : leaves erect-appressed, broadly ovate or oval-
lanceolate, carinate-concave, apiculate by the slender subexcnr-

8 6 . ZIERIA, Schimp.
Plants short, cespitulose, branching by innovations under the
flowers, then dichotomous. Stems radiculose up to the apex.
Leaves soft, more or less densely imbricate, ovate and oblong-
acuminate, apiculate or cuspidate by the excurrent costa; areolation
broadly hexagonal-rhomhoidal. Flowers gemmiforrn.
Capsnle horizontal or curved down, short-pedicelled, very long-
necked, narrowly elliptical, sporangium inflated. Lid small,
convex-apicnlate, oblique. Peristome double; the teeth narrowly
lanceolate, remotely articulate ; inner membrane divided
into narrow segments, often united at the apex by transverse
divisions, separ.ated by rudimentary cilia.

stems short, divided into numerous erect branchlets: lower
stem-leaves remote or destroyed hy maceration ; comal leaves
ohlong-lanceolate, those of the branchlets densely imbricate,
broadly ovate, concave, acuminate ; inner costa soft, excurrent ;
areolation vei-y broad and soft, chlorophyllose at the base only,
hyaline above : capsule horizontal or slightly inclined ; collum
twice as long as the sporangium ; lid convex-conical, acute,
orange-colored, the capsule being yellowish-brown ; teeth orange
at base, subulate and whitish at the apex. — Coroll. 68. Bryum

2. Z. d em issa , Schimp. Tufts dense, reddish brown,
densely matted by a felt of radicles : stem-leaves ovate-lanceolate,
costa vanishing below the apex ; comal leaves ohlong-
lanceolate, long-cuspidate hy the excurrent costa ; branch-leaves
loosely imbricate : capsule curved down on an arched pedicel,
clavate, its collnm and sporangium of equal length, yellow,
chestnut-colored when old ; lid small, mamillate, oblique ; teeth

8 7 . MNIUM, Linn. (PI. 3.)
Plants larger than in Bryum, gregarious, or more generally
loosely and -widely cespitose. Stems produced from hasilar
innovations or from subterranean stolons, woody, tomentose,
rarely divided and .sometimes bearing arcuate creeping flagelliform
branchlets. Leaves 3-5-ranked, the lower smaller, distant,
the upper much enlarged, crowded and rosulate, broadly ovate
or spatulate; costa stout; bordéis thick, simply or doubly
dentate ; cells of the areolation very large, round-hexagonal,
hexagonal-oblong near the base, rarely chlorophyllose. Flowers
bisexual or dioecious ; the male discoid ; antheridia and clavate
paraphyses axillary, very numerous. Calyptra cucullate, narrow,
