IIab . On wet rocks in mountains, or northward, from New England to
the Rocky Mountains and Canada.
Variable, in more or less compact densely tomentose tufts. The dark
green color of the tufts, the slender stems, aud the shorter leaves give to
this moss an appearance different from that of the following species.
6. B. pomiformis, Hedw. Tufts deep, flat and wide, or
smaller and pulvinate, yellowish green above, pale brown and
tomentose within: leaves open or erect-spreading, curved or
cirrhate when dry, lanceolate, carinate, sharply serrate above,
the borders revolute from the middle downward; costa percurrent
or excurrent into a short spinulose awn : flowers androgynous
(male and female flowers contiguous) : capsule
spherical, long-pedicellate; outer teeth regular, densely articulate
; segments shorter than the teeth, cleft open ; cilia simple,
short or rudimentary. — Spec. Muse. 164; Bryol. Eur. t. 319.

Var. c risp a , Schimp. Stems and leaves longer, narrower,
cirrhate-twisted when dry: capsule short-pedicellate. B.
crispa, Swartz.
Ha b . Shady banks and fissures of rocks; common on the eastern
slope, in valleys and mountains; Columbia River, Oregon (Uall, Nevius).
7. B. H a lle rian a , Hedw. Plants soft, in bright green
tnfts : leaves long, narrowly subulate from an enlarged whitish
half-clasping base, serrulate above, spreading all around the
stems or inclined on one side, flexuous when dry : flowers as in
the preceding species : capsule on a short curving pedicel, often
binate, becoming lateral or as if axillary by the continuous innovations
of the stems, pale brown ; lid very small, convex-conical
; teeth dark brown, incurved when dry. — Muse. Frond, ii.

Ha b . Rocky Mountains, Portage Eiyer (Drummond).
8. B. ra d ic a lis , Beauv. Plants soft, loosely tufted, glaucous
green, tomentose their whole length ; stems short, prostrate
at base, branching from below the floriferous apex : leaves
erect, open and subsecund, linear-lanceolate, cuspidate by the
excurrent costa, sharply serrate, papillose on the inner face
only; perichætial broadly ovate, abruptly and narrowly long-
acuminate from the enlarged base : flowers monoecious, the
male gemmaceous, close to the fertile ones ; perigonial leaves
broadly concave at base, long-suhulate above : capsule on a long
slender flexnous pedicel, globose, subhorizontal ; lid very small,
conical-apiculate; teeth lanceolate-suhulate at the apex, dark
orange, longer than the segments; cilia short or rudimentary.

Hab. On the ground in wet springy places and margins of swamps in
the Southern States; not uncommon.
Allied to B. rigida, a European species, which has less linear leaves
witli only the lower surface papillose, reflexed margins, a thicker shorter
pedicel, and an oblong-globose capsule with a thicker outer membrane.
B. Wilsoni, Muell., is reported in Rau & Hervey’s catalogue as found
in New Jersey by Austin. We have seen no other mention and no specimens
of it. It is a small plant, with soft subsecund leaves ; capsules aggregated
in the same perichætium, very soft, on arcuate pedicels, globose-
pyriform, without peristome.
76. CONOSTOMUM, Swartz. (PL 3.)
Plants erect, in small compact tufts, fastigiately branching,
tomentose-radiculose. Stem-leaves equal, the comal longer,
densely crowded, imbricate in five ranks, the stem appearing
pentagonal ; areolation of the leaves the same as in Bartramia.
Flowers dioecious, the male discoid. Calyptra cucullate, persistent.
Capsule long-pedicellate, cernuous, inflated, obovate
from a short collum; lid small, straight-beaked. Peristome
simple, of 16 solid linear-lanceolate teeth, joined into a cone
and agglutinate at the apex.
1. O. b o re a le , Swartz. Tufts glanoous-green above : lower
leaves lanceolate, costate to below the apex, the upper narrowly
lanceolate, longer cuspidate by the excnrrent costa, all carinate,
serrate above, opaque and brittle ; perichætial leaves numerous,
larger, thinner, with a slender costa ; outer jierigonial leaves
lanceolate from a broadly concave base, the inner gradually
shorter : capsule sulcate when dry, cernuous ; teeth latticed,
purple. — Schrad. Neu. Journ. Bot. i. 3. 26, t. 4. Bryum tetrag-
