Cephalozia denudata., Spruce, On Cephalozia (1882).
Dioicous, intricately cæspitose, flagelliferous, small, greenish-
to reddish-brown in colour. Stems almost leafless at the base,
rhizomatous, creeping, subramose, cortical cells about 40, similar
to the inner, 10 x 8 cells in diameter; branches subfascioulate,
erect, gemmiparous ; radiculose, rootlets numerous on the creeping
stems ; flagella postical, few. Leaves imbricate, patent-divergent,
never secund, concave, broadly ovate or oval, entire, sometimes
retuse or emarginate, slightly decurrent antioally, largest near the
middle of the stem, becoming gradually smaller above and
gemmiparous ; texture firm ; epidermis verruculose ; cells small,
roundish-quadrate, walls thick, angles thickened, no trigones.
Stipules everywhere present, increasing in size on the gemmiparous
branohes and becoming equal in size to the terminal leaves,
oblong-roundish-quadrate, broadly oval or lanceolate, entire, acute
or subdentioulate. Inflorescence j postieal ; sub-braots oval or
ovate, bidentate to about a sixth ; sub-braoteole oblong, entire ;
bracts twice bifid, margin denticulate or rarely entire ; bracteole
lanceolate, acute, minutely bidentate. Perianth narrowly fusiform,
oylindrioal below, above obtusely trigonous, mouth small,
denticulate or shortly fimbriate, at the base 3 cells thick, near
the middle 2, upper half composed of a single layer of cells.
Calyptra very delicate, composed of a single layer of cells.
Pistillidia long, narrow, about 12. Andrcecia postical, araenti-
Ibrm, arcuate-decurved, perigonial bracts 3-8 pairs, deeply
saccate, margin entire, emarginate or incised, segments obtuse or
obtusate.

matter, or on crumbling sandstone.
Somewhat rare ; very rare in fruit.

Obs.—Differs from Cephalozia (0.) Sphagni (Dicks.) in its
intricately branched leafless eaudex, branches usually erect, attenuate,
gemmiparous ; leaves never secund, destitute of any distinct
margin, epidermis verruculose, abundant presence of stipules
everywhere.
Ceph. (0.) Sphagni (Dicks.) has stems often repeatedly arcu-
ately branched, which are equally leaved throughout, often
secund, with a distinct margin, stipules absent or few and extremely
minute.
“ Ceph. (0.) denudalais usually found growing on rotting wood
or crumbling sandstone; Ceph. (0.) Sphagni on \\Cmg Sphagna
and other bog mosses.” II. S.
