Plants large, rarely small, pale or yellowish-green, rarely very
green, densely cæspitose, tufts depressed, rarely erect or pendulous.
Stems in many species firm, beautifully feather-hke, pinnate or
bipinnate; branches lateral, sometimes attenuate and radiculose
at the apices, rarely, and principally in small species with postical
branches, which are frequently flagelliferous and radiculose. Leaves
incubous, small, in some species very minute, sometimes broader
than long, very oblique, witli antica! margin much longer and
rotundate, decurvo-oonoave, palmate or quadrifid almost to the
base, rarely 5-6- or only 2-3-fid, segments subulate, entire or
furnished at the antical base with a few teetli, in a few species all
the margin dentate; cells usually smallish, quadrato-hexagonal,
inferior subelongate, angles slightly thickened, cuticle often rough ;
in Micro-Lejndozia very small oblong-quadrate. Stipules similar
to the leaves but symmetrical, in Eu-Lepidozia slightly smaller, in
Micro-Lepidozia about half the size of the leaves. Inflorescence
dioicous, in a few species (chiefly Alicro-Lepidozia) monoicous;
Î on the stem, rarely on the branches, hypogenous. Bracts 3-5
pairs, appressed, concave, innermost frequently about three times
(in small-leaved species up to eight times) larger than the leaves,
at the apex 2-4-fld, margin denticulate or spinose. Pistflhdia
20 or less, the sterile surrounding the base, or a little higher.
of the calyptra. Perianth almost always elongate, ovate-subulate
or narrowly fusiform, upper portion obtusely trigonous, in Eu-
Lepidozia carnose, mouth entire or denticulate, Micro-Lepidozia
leptodermous, mouth oiliato-laoiniate. Calyptra, 2-4 times shorter,
pyriform or oblong, below somewhat carnose, or in Micro-Lepidozia
whole length delicate, afterwards rupturing into two lips. Capsule
on a more or less firm shortly exserted pedicel, oblong-cylindrical,
dividing to the base into 4 valves, 2-4-strata. Elaters slender,
bispiral. Spores minute, smooth or asperuloiis. Androecia very
often constantly on slender postical branches, rarely (and in
Micro-Lepidozia principally) terminal on lateral branches; perigonial
bracts 5-10 pairs, suborbioulate concave, apex bidentate ;
antheridia solitary large pedicellate.

Dioicous, densely cæspitose, flagelliferous, medium size,
greenish to olive or reddish-brown in colour. Stems creeping or
suberect, curled, on a cross-section i6 x 20 cells in diameter,
cortical about 50, these and the next inner layer large with thick,
dark vi alls, inner cells smaller with thinner walls, of a light golden
brown colour; closely pinnate or bipinnate, branches alternate,
unequal, often attenuate, apices flagelliferous. Leaves incubons,
closely imbrioate, patent or patent-divergent, incurved, very concave,
cordate-orbiculate or broadly subquadrate-cordate, quadrifid
to nearly the J, segments acute, 8 to 12 cells broad at the base,
sometimes even more, postical segments much inflexed; cells
smallish, opaque, subquadrate-hexagonal, walls thick, angles
