1. B. Menziesii, Turn. Plants more or less densely cespitose;
steins 6 to 10 c.m. long or more, simple or sparingly
branched, brown within the tufts, bright or yellowish green
above : leaves closely imbricate, erect or half open, concave,
plicate and reflexed on the borders at the enlarged ovate base,
lanceolate, subulate-dentate above ; costa stout, percurrent,
rough on the back; perichætial leaves similar; perigonial
broadly ov.ate, deeply concave at base, abruptly long-subulate,
scabrous on the back : flowers dioeoious ; male plants simple,
shorter, the flowers terminal or lateral hy innovations, gemmaceous
; antheridia curved, yellowish brown with numerous long
filiform paraphyses ; fruiting flowers lateral by innovations :
capsule erect, broadly oval, symmetrical, pale brown ; pedicel
short, 1 to 2 m.m. long, pale red or dark yellow, twisted to the
left ; lid conical, obtuse : peristome simple, of 16 short lanceolate
irregularly articulate reddish teeth, sometimes rudimentary or
none. — Koeii. & Sims, Ann. Bot. i. 525, t. 11, f. 1; Hook.

Hah. California, not rare; Spokan Falls ( Watson). The normal form
on shaded i-ocks in the woods, varying on dry exposed rocks.
The species varies according to its habitat. Qn dry exposed rocks the
stems are shorter, the slightly shorter and narrower leaves, appressed
when dry, are open and erect when moistened ; the capsule is somewhat
longer and narrower ; the peristome either wanting or fragmentary and
reduced to a pellucid membrane more or less irregularly lacerated. This
is the variety n. 260 of the Muse. Exsicc. (n. 259 by mistake), and represents
Glyphocarpa Baueri. It is not possible to ascertain which of the
two forms represents the original species of Hooker, as no author appears
to have seen the peristome complete. The specimens in Taylor’s herbarium
have longer stems and short oval capsule, like the normal form, but
no peristome, and therefore combine characters of both forms.
2. B. su b u la ta , Bruch & Schimp. Plants in short compact
tufts ; stems slender ; upper leaves more densely crowded,
erect-open, strict, rigid, glaucous-green when young, linear-
subulate and sharply serrate above the ovate half-clasping base ;
costa subpercurrent : flowers androgynous ; antheridia mixed
with the archegonia or separated by a single leaf only : capsule
on a strict short reddish pedicel, globose-ovate, marked from
I
the middle upward with obscure striæ, furrowed-plicate when
dry and empty ; lid small, convex, conical ; teeth either present,
narrow, unequal and orange-colored, or absent and the orifice
surrounded by a short thin pellucid membrane. — Bryol. Eur.
t. 315.
Hab. Colorado [Brandegee); Sitka (Bothrock); Flower Bay, Alaska
{Ball).
3. B. str ic ta , Brid. Tufts compact, glaucous-green above :
leaves open, erect, strict, straight and fragile when dry, lanceolate
subulate, serrate above ; meshes of the areolation smaller
than in the preceding species ; costa excurrent into a spinescent
awn : flowers bisexual : capsule ovate-globose, erect, rarely
slightly cernuous, sulcate-ribbed when dry; pedicel strict,
obscurely tetragonal above and twisted to the right ; lid convex,
obtuse, short-mamillate and erose ; teeth either regular
and entire or irregular at the borders, perforated along the
dividing line, yellow : spores verrucose. — Muse. Recent, ii. 3.
132, t. 1, f. 5 ; Bryol. Eur. t. 316.
Hab. Eocks near San Francisco (Bolander, Gibbons); Colorado
(Parry).
* * Capsule curved ; lid oblique ; peristome double.
4. B. itb y p b y lla , Brid. 1. c. Stems longer than in the
last : leaves open-erect, strict, enlarged, white and clasping at
base, linear-subulate and coarsely serrate above; costa thick,
gradually occupying the whole lamina above : flowers bisexual :
capsule globose-oblong, more distinctly curved and deeply furrowed
when dry ; lid conical-obtuse ; teeth reddish brown, irregularly
perforated, sometimes bifid at the apex ; inner segments
yellow, cleft, much shorter than the teeth. — Bryol. Eur. t. 317.
Hae. Fissures of rocks on mountains; White Mountains, Adiron-
flaeks, Rocky Mountains, Sierra Nevada and Cascade Mountains, Sitka,
etc. Also rarely on the plains; Fayette County, Pennsylvania (Knight).
Varies with shorter fragile leaves, not as white at the base, and not as
abruptly narrowed above it.
5. B. OEderiâna, Swartz. Plants slender, loosely tufted,
dark green above : leaves open and recurved, soft, twisted when
dry, narrowly lanceolate, plicate, carinate and serrate toward the
apex ; borders more or less revolute ; costa narrow, percurrent,
serrate on the back above : flowers bisexual : capsule small,
globose or ovate-ohlong, incurved and ribbed when dry; pedicel
slender and slightly curved, of medium length; lid and
