Fl. fasc. 19, p. 38, t. 10 (1835).
Heteroicous (monoicous and paroicous), depresso-cæspitose,
medium to largish in size, pale to dark green in colour. Stems
prostrate or apices assurgent, moderately firm, simple or rarely
furcate, branches postical, elongate, attenuate, gemmiparous ;
radiculose, rootlets many, proceeding in tufts from base of the
stipules. Leaves usually small at the base and at apex, largest at
the middle of stem, imbricate, incubous, alternate, patent-divergent
or horizontal, slightly convex, ovate, entire, apex rotundate or
rarely acute, or very slightlj' bidentate, cells lax, oblong-hexagonal
or hexagonal, medium to rather large, walls thin, trigones very
small. Stipules nearly half the size of the leaves, about twice as
broad as the stem, subrotund, bifid to about a third, retuse or
subentire, lobes obtuse, sinus obtuse, margin entire. Bracts verj'
small, 2 or 3 pairs, oblong-quadrate, slightly bifid. Perianth
arising from axil of stipule, pendulous, subterraneum, cylindrical
or subolavate, carnose, composed of several layers of cells, near
base 6 layers, near the moutli surrounded by layers of small and
broadly subulate scales, which are often found on other parts of
the perianth ; radiculose, rootlets long delicate hyaline, interior
layer covered with long papillæ, composed of single, elongated
cells. Calyptra free, 2 - 4 cells thick near the base, pistillidia
long, narrow, about 10. Pedicel thick, about the same diameter
as the capsule. Capsule cylindrical, 3 to 4 times longer than
broad, composed of two layers, valves spiral, linear. Spores pale
brown. Elaters reddish-brown, 2 0 -3 0 turns of the spiral, bispiral.
Androecia bud-like, sometimes catkin-like, postical, situated in the
axil of the stipule, near the ?, perigonial bracts very small,
about 3 to 4 pairs, subrotund, trifid, segments acute, sinus obtuse,
antheridia about 10, oval.
Gemmæ often pedicellate, in spherical heads, yellow-green.

O b s .—This is a very distinct species, and cannot well be confounded
with any other, except the following, which see.
The attenuate, gemmiparous stems, the rotundate, acute or
slightly bidentate leaves, the lateral, pendant perianth and cylindrical
capsule distinguishing it from other species.
Kantia arguta (Mont.), the other British species of this genus
is a much smaller, more delicate plant, with deeply bidentate
leaves, and is dioicous.
H a b .—Growing in moderate-sized patches in hogs, on damp
or wet banks in woods, &o. Common.
