Dioicous, loosely cæspitose, small to medium in size, of a
green or brown colour. Stems simple or furcate, or innovantly
branched, suberect, fle-xuose, brandies subpostioal-lateral, qjroceed-
ing from apex of stem, filiform, attenuate, with small closely
appressed leaves ; radiculose, rootlets plentiful, long, whitish.
Leaves imbricate or approximate, obliquely inserted, patent or erect-
patent, oval-quadrate, quadrate, concave, bifid, trifid,or rarely quad-
rilid, irom about g to deep; leaves on the attenuate branches small,
closely appressed, erect, imbricate, erose by the development of
gemmæ; cells small, 4-, 5-, and 6-sided, lumen filled with chlorophyllose
granules, walls moderately thin, trigones small, distinct.
Stipules wanting or minute, linear, subulate, near the bracts distinct
(sub-bracteoles), ovate-lanoeolate, bifid to about the middle, margin
entire. Bracts larger than the leaves, spreading, quadrate or
broadly roundish-quadrate, trifid or quadrifid to about segments
acute, unequal. Bracteole ovate-lanceolate, bifid to about the
middle, connate with an adjoining bract, rarely free. Perianth
terminal, projecting about I beyond the bracts, cylindrical, oval-
oblong, oval or ovate, upper half acutely 5-plioate, lower half
slightly folded, 2 layer of cells thick at the base, higher one cell
thick, mouth contracted, ciliolate. Calyptra 2 cells thick at the
base, one higher where it is thin and delicate. Capsule oval,
reddisli-brown. Spores round, brown. Elaters bispiral.
Male stems spicate ; perigonial bracts usually terminal, transversely
inserted, closely imbricate, 5-6 pairs, ventricose, conduplicate,
bifid with, a large tooth on the antical side (trifid), apices
incurved ; antheridia one or two in each bract, oval. Gemmæ
terminal at the ends of the leaves, yellowish-red or green, irregular,
oval or angular.
Fruits April, May.

O b s .— This is a very poljunorphous species, and varies much
in size; it is not likely to be confused with any other species on

var. atlenuata {Jung, aifenuata (Mart.) Lindenb.), but Schleicher’s
name has the priority, and is quoted by Nees, “ Eur. Leber.,”
