D io ico u s ; in wide-spreading pa tches, olivaceous-green, often with
a rufous or fuscous tin t. Stems dichotomous, J— 3 in. long, fa s tig
ia te , radiculose below. L e a v e s e recto-patent, la xly imbricated,
incurved and somewhat tw isting when dry, oblongo-lanc., subcomplicate-
con cav e , margin revolute, becoming plane a t apex, entire or slightly
denticulate at point ; nerve lost a t ape.x or forming a cuspidate point ;
ce lls a t base pellucid, elongate, 4— 5 angled, above rounded-quadrate,
nearly smooth, obscure and chlorophyllose. Perich. b ra cts longer, the
innermost longly convolute-vaginant, sinuate above, and often suddenly
a cuminate and crenulate at apex. Cap s, on a long purple shining seta,
inclined, oblong, tu rg e scent, stra ight or a little curved, purple or rufofuscous,
sulcate when dry and empty, strumulose, horizontal, incurved,
4— 5 angled ; annulus large, compound, rolling back, lid conic, slightly
oblique, polished ; teeth o f per. purple in lower half, the legs equal, con joined
at base by the united a rticu lation s, bordered from base to middle
by the pale pro jec ting inner lamina.
Male plants more slender, infl. gemmaceous, outer b racts broadly
ovate, a cuminate, with a th ick nerve, inner broadly convolute, obtuse,
entire, obsolete-nerved.
H ab.— Gravelly soil on heaths, banks, walls and rocks ; everywhere. Fr. 4— 5.
The polymorphous character of this plant may be assumed from its
lengthy synonymy, and so endless are the forms that we cannot even define
stable varieties ; one of the most marked is a robust livid-green one, i— 2 in.
high, with broad leaves, found on several of the Scotch mountains, and also
by Mr. Holt on banks near the sea in the Isle of Man. W e would advise all
commencing bryologists to study every part of this moss well, as its structure
once familiarized to the eye will save much after trouble, and the beautiful
peristome must attract every microscopist.
2. CERATODON CONICUS {Hampe) Linib.
D io icou s ; lea ves ovato-lanc. narrower a t base, margin entire, revolute
throughout, nerve longly excurrent. Capsule on a paler seta, erect,
symmetric, faintly sulcate when empty. (T . X X V I , E.)

Ceratodon conieus L i n d b . M u s c . scand. 37 (187g).
D io ico u s ; cæspitose, dull yellow-green above, fuscous b e low ;
stems short, rather slender dicho tomously branched. Le a v e s erecto-
appressed, deep green, smooth, crowded at top into a small closed
coma, stra ight w e t or dry, rather broadly ovato-lanceolate, margin quite
entire, revolute to apex, nerve th ick, excurrent in a long point ; cells all
small, regula rly quadrate, th e basal larger and pellucid. Perich. bracts
convolute-vaginant, obtusate, with an excurrent nerve, la xly areolate.
Caps, on a pale red seta, erect, ovate-elliptic, rather wide, fuscous, when
dry and empty but little altered, sulca te in upper part, not strumulose ;
lid purple, conic short, obtuse straight ; te e th pale, red at base, yellowish
above, erect, with fewer articulations, s ca rc e ly bordered externally.
H ab.— Wails and waste ground, rare. Fr. 5.
On the coast near Newhaven (Spruce 1S45) • • Ireland {Mr. D. Orr). Both sterile.
It is probable that this moss is not unfrequent on our south coasts, but
has been overlooked for the common species in the absence of fruit ; this was
lirst iound by Schlotheuber in IMa)', 1847, on walls near Hochmiihlen, in
Hanover, and our figures are taken from original specimens.
