a
mens of three of Drummond’s sets has failed to show a single dioecious
plant; hence Schimper’s reference is still uncertain.
11. M. o r th o r rh y n c h um , Bruch & Schimp. Dioecious.
Differs from the preceding iu the inflorescence, the plants
somewhat more solid and more densely foliate, with a slightly
smaller areolation, the teeth more acute, the costa spinulose on
the hack, the male flowers discoid and polyphyllous, the capsule
subventricose, slightly curved upwards, as also the beak of tho
lid, which is sometvhat longer and thicker, and the spores twice
as largo. — Bryol. Eur., t. 391.
I I a b . Niagara Falls (Clinton); Easton, Penn. (James); Ontario (Macoun);
Colorado (Rothrock & Wolf); British America (Drummond).
12. M. ly c o p o d io id e s , Schwaegr. Dioecious : plants loosely
cespitose, slender, dirty gi'een : lower leaves distant, ohlong, the
upper gradually larger and long-lingulate, the perichætial sublinear,
all cuspidate hy the excurrent reddish brown costa ;
teeth of the brown margin close and sharply acute ; areolation
dense : capsule horizontal, longer than in the last two species,
subcylindrical and more or less inoiirvod, brown ; teeth longer.
— Suppl. ii. 2. 24, t. 160 ; Bryol. Eur. t. 392.
H a b . Borders of rocky brooks in pine woods; Adirondack Mountains
(Lesquereux); White Mountains (James); Canada (Mrs. Eoi/).
13. M. um b r a tile , Mitt. Dioecious : plants loosely cespitose
or gregarious, dark green : leaves loosely spreading, the
lower smaller, ohlong, acute or very entire, the upper elliptical-
oblong, short-apiculate, long-decurrent, with narrow donbly
serrate borders ; costa percurrent ; cells of the areolation
rounded, thick-walled ; inner perichætial loaves short, lanceolate,
the oiiter long-linear, narrower than those of the stem : capsule
solitary, cylindrical-oblong, narrowed at base, curved, subinclined
or horizontal on a long reddish flexuous pedicel ; lid pale, conical,
beaked. — Journ. Linn. Soo. viii. 30 ; Sulliv. loon. Muse.
Suppl. 51, t. 85.
H a b . Mountain Eocks, Portage Eiver ( Drummond) ; Galton Mountains,
British Columbia (Lijall).
Resembles in its foliage M. serratum, Brid., but is allied by its inflorescence
to M. orthorrhynchum, differing from it in its softer leaves, with
cells four times as large, and also from the last species, whose cells are
only half as large and the comal leaves long and narrow.
14. M. s p in o s um , Schwaegr. Dioecious : plants widely
and loosely cespitose, stout, dark purple, often 2-3-parted;
branchlets densely foliate, flagelliform : lower leaves small and
distant, squamiform, oblong, obtuse, entire, scariose, the upper
and comal abruptly larger, spreading open, crispate when dry,
ovate or ohlong-acutninate, spatulate ; perichætial leaves narrower,
shortly cuspidate by the excurrent brown costa, margin
purplish brown ; teeth spiniforra : male plants mixed with tho
fertile or in separate tufts : capsules clustered (1 to 5), ovate-
ohlong, solid, horizontal or inclined on a reddish pedicel ; lid
conical, obtusely beaked. — Suppl. i. 2. 130, t. 78 ; Bryol. Eur.
t. 393. Bryum spinosum. Voit in Sturm, Deutschl. FL ii. t.
Hae. Under low pendent branches of pines, in middle districts of the
Rocky Mountains (Downie); very rare.
A beautiful species, easily distinguishable by its dark green foliage, the
leaves abruptly longer at the top of the stem, and the male flowers
rosulate.
15. M. s p in u lo s um , Bruch & Schimp. Synoecious: resembling
the last; plants less robust, bright or yellowish green:
leaves hroadei-, longer-deourrent at base, more abruptly enlarged,
obovate-oblong, less crispate when dry, apiculate by the excurrent
costa; margin reddish ; outer perichætial leaves narrowly aoumi-
nate-lyrate, the inner very small, lanceolate : capsules generally
clustered (2 to 6), smaller and shorter, mostly pendent or more
inclined, thin, greenish yellow when ripe, yellowish brown when
empty ; lid narrower, conical, short-beaked, orange-colored.
Bryol. Eur. t. 394.
Hab. Pin e woods in the mountains: not rare.
Tiiis species is very rare in Europe, while the preceding is quite common
in the Jurassic or subalpine region. It is the reverse for the distribution
of tliese two species in North America.
* * * Leaves without margins, serrate or entire.
-I- L id highly convex, obtuse or apiculate.
16. M. s te lla r e , Reichard. Dioecious : suh-cespitose, pale
green; leaves soft, gradually larger up to the apex of the stems,
open, erect, slightly decnrrent, oblong and long elliptical-acuminate,
the lower nearly entire, the upper simply and irregularly
dentate ; perichætial leaves longer and narrower; costa slender,
vanishing abruptly below the apex : capsule solitary, horizontally
inclined, ovate-ohlong, nearly regular, soft; lid orange, convex,
obtuse. —Hedw. Spec. Muse. 191, t. 45; Bryol. Eur. t. 401.
