G e n u s 1 4 . BLEPHAROSTOMA, Dumort.
Involucre many- leaved, e v e r ywh e r e imbricate,
perichæt ial leaves articulate-ciliate. P e r i anth
sessile, erect, terete, ovoid, naked, mouth
clad with long art iculate cilia. Capsule four-
valved, coriaceous, naked. Elaters double,
naked, deciduous.— Dumort. Rev. Ju ng. p. 18.
(1835-)
Plants delicate, without stipules, leaves transvers-
ally or vertically plane, or parted nearly to the
base, segments setaceous.
Blepjiarostoma, although at first sight so different
from Cephalozia in the quadripartite leaves,
with filiform crura, has the involucre and perianth
formed on the same plan, the bracts being tristichous
and mostly trijugous, and the perianth,
when young, distinctly trigonous (with the third
angle postical), although at maturity it becomes
nearly terete, and is trigonous only at the many-
ciliated apex. The dichotomous ramification,
without a single postical branch, and the constantly
terminal female flowers separate it from
Cephalozia and assimilate it to Pleuroclada.”—

Growing in loose matted tufts, some inches
broad. Stems creeping ^ to i | inch long, simple
or forked, shoots with short
spreading branches. Leaves in
alternate clusters of two or three
to five, forming tufts, simple or
forked, setaceous, straight, yellowish
green, paler when dry,
transversely septate (fig. 69)
Perichætial leaves, external similar
to stem leaves, internal nearly

ovate, entire ¡at the base, but
divided above into branched capillary segments.
Perianth elliptical, plicate, contracted at the mouth,
and fringed with short hairs. Calyptra ovate,
white. Capsule ovate, then splitting into four
