17. B. pro v in cia le , Philib. Loosely cespitose ; stems short,
divided by few innovations, radiculose at base : branch-leaves
few, distant, smaller, ovate-lanceolate, the upjjer crowded in
tufts, spreading when moist, loosely appressed and undulate
when dry, ovate-oblong, concave, acuminate or cuspidate by tlie
excurrent stout reddish costa; borders narrowly recurved from
the middle to the base, plane, minutely serrate toward the apex ;
inner or perichætial leaves smaller, lanceolate, longer pointed ;
borders revolnte or broadly reflexed to near the apex : flowers
partly bisexual, the fertile always unisexual; vaginule thick,
covered with abortive archegonia and paraphyses : capsule
oblique or pendent, on a reddish pedicel, obconical-pyriform,
brown-orange ; lid highly convex, apiculate ; teeth yellow up to

18. B. Oreganum, Sulliv. Densely cespitose ; stems and
innovations very short, gemmiforrn: leaves crowded into a
subglobose tuft, oblong or obovate-oblong, pointed, serrate
above ; borders margined and reflexed ; costa extending to the
point ; areolation rather loose ; perichætial leaves elongated-
oblong, long-pointed with a subexcurrent costa ; capsule suh-
pendent, on a slender pedicel 3 to 5 c.m. long, clavate, oblong,
straight or slightly curved, constricted below the mouth when
dry; lid rather small, hemispherical, apiculate; teeth closely
articulate ; segments broad, cleft ; cilia 2, strongly and conspicuously
appendiculate; annulus large and compound.—Muse.

H a b . Oregon (Pickering).
Species closely related to B. microstegium, Schimp., but that has ovate-
lanceolate leaves, gradually acuminate and long-cuspidate by the excurrent
costa, with margins not reflexed, a convex-conical more pointed and
smaller lid, and more linear teeth with more distant articulations.
* * Flowers moncecious.
19. B. pa lle sc en s, Schleich. Subcespitose and pulvinate;
stems somewhat long, branching, radiculose, purple: lower
leaves distant, ovate, aouminate; costa vanishing helqw the
apex; comal leaves crowded into a spreading tuft, oblong-
acuminate, apiculate or cuspidate by the excurrent costa, reddish
at base, more or less revolnte on the entire border : male flowers
on separate lateral branches : capsule long-neoked, oblong-pyriform,
mclined or horizonal, constricted under the orifice when
dry ; lid bright reddish-brown, conical, apiculate ; teeth yellow ;
segments longer and more aouminate than in the preceding
species. — Schwaegr. Suppl. i. 2. 107 ; Bryol. Eur. t. 359.
I I a b . Fissures of sandstone rocks, Ohio to Canada; also in Colorado,
Utah, California and Washington Territory.
Tlie stems of this species vary in length and are more or less divided,
the leaves eitlier long-cuspidate or abruptly acuminate are always reddish
at base, and the capsule varies in the length of its collum; the lid is
smaller tlian that of B. cæspiticium, which this species resembles.
20. B. subrotundum, Brid. Plants short, gregarious,
much divided into short gemmiforrn innovations : lower leaves
small, broadly ovate-acuminate, mucronate by the excurrent
costa, the upper abruptly larger, densely crowded into tufts,
ovate and ohlong-lanceolate, the perichætial lanceolate, all
shortly aristate by the excurrent suhdentionlate costa, concave,
flat on the borders, soft : capsule inclined or pendent, spherical
or oblong-pyriform, with a narrow orifice, slightly constricted
under it when dry ; lid small, conical, mamillate ; peristome as
in the preceding. — Muso. Recent. Suppl. ill. 29; Muell. Syn.

Differs from B. pallescens in its concave broader leaves, with a shorter
point and the borders not reflexed, the capsule nearly pendent, shorter
and broader, the sporangium being nearly round, the orifice small.
