Growing in more or less crowded patches of
some inches diameter. Stems i to H inch long,
procumbent, flexuose, branched, the branches often
erect, towards the extremity simple, or with a
short lateral shoot. Leaves close but scarcely imbricated,
in two opposite rows, plane or slightly
waved, horizontal, broadly ovate at the base, half
surrounding the stem, the lower margin very decurrent,
divided at the apex for one-quarter or one-
eighth of their length with a more or less acute sinus,
into two equal sharp straight segments, the tips of
which resemble cilia. Colour light green. Perichaetial
leaves, the first pair are twice the length of
the stem leaves, quite erect and adpressed, deeply
divided into two equal lanceolate segments, which
are sometimes dentate at the margin. Stipules, one
to every pair of leaves, adpressed to the under side of
the stem, oblong, generally divided into two, sometimes
three, segments, here and there dentate.
Calyx sometimes slightly incurved in an early stage,
ovate-oblong, obtusely triangular, mouth slightly
contracted at first, afterwards somewhat expanded,
with a deep incision on one side, and bordered with
numerous laciniæ. Capsule ovate, deep brown,
longitudinally and transversely furrowed. Elaters
bispiral.
