O b s .— Very similar to large bog forms of C. bicuspidata (L.),
but distinguished from them by its dioicous inflorescence, the
female flowers on long branohes, absence of flagella, whitish or
dull brown colour (never rose coloured), tbe large, unequal,
acuminate leaf segments, presence of stipules on the male plants,
the deeply divided bracts with entire margins.

6. Cephalozia hibernica, Spruce MS.
Cephalozia hihemica. Spruce MS. Pears, in “ Irish N a tu ra list,” Dec. (1894).
Dioicous, creeping amongst mosses, with few rooting flagella,
small, of a whitisli, crystalline or pale green colour. Stems stout,
flexuose, ramose, procumbent or somewhat erect, qflano-convex,
antical aspect 3-4 cells wide, postical with a band of 4 x 5 much
smaller cells; branohes postical, irregular, sometimes attenuate
and gemmiparous, gemmae capitate ; rootlets hyaline, on the lower
part of the stem, or at the apices of the arcuate stolons. Leaves
approximate or contiguous, alternate, almost horizontally inserted,
deourrent at the base, subalate, plane, so that the stem appears
bialate, bifid from a third to the middle of the length, sinus
rounded, segments subconnivent or erect, sharply acuminate, apical
cells 2-4 in single series, texture delicate, cells large, hyaline,
4-, 5- and 6-sided, surface pitted when dry as in Ceph. connivens,
walls thick, trigones wanting. Stipules absent. Flowers ? terminal
on very short postical branches, bracts oblong, divided to
about two-thirds into two unequal lanceolate-acuminate segments,
sub-bract smaller, divided to about the middle, sometimes with a
third small segment on one side, segments acute; bracteole oblong,
bifid to about the middle or entire, unidentate near the middle,
segments lanceolate-acuminate; sub-bracteole oval, divided to
about segments obtuse, third sub-bracteole small, slightly bifid.
Immature perianths only met with, mouth fringed with long cilia,
12 to 15, each composed of 3 or 4 long single cells. Andrcecia
on short postical branches, perigonial bracts 4-5 pairs, closely
imbrioate, complicate-concave, oval, bilobed to about one-third ;
antheridia single, oval.
