H a b .—Growing on somewhat damp rooks, stones, earth or
rotting wood, exposed or shaded ; on heaths, or creeping upon
other hepatics or on mosses. Very common.

Europe, Asia and North America.
O b s .— A common and variable species, which has stipules
always near the bracts, but on other parts of the stems sometimes
without and sometimes with. The type with stipules has
been considered a distinct species (Cephalozia Starkii, Funck), but
agreeing with Dr. Spruce, I find no other characters of sufficient
value to make it worthy of specific rank.
C. divaricata is a small species with wiry stems distinguished
from its nearest allies Ceph. Jaclcii, Limpr. and Ceph. stelldifera
(Tayl.) hy its dioicous infloresoenoe.
Ceph. leiicantha. Spruce, wliich is also dioicous, is of a much
paler colour, stems more fragile, leaves more oblong, with segments
parallel or connivent, not divergent, stipules always absent.

Monoicous, acrocarpous or cladocarpous, densely cæspitose
eflagelliferous, small, pale green or subolive to reddish-brown
Stems creeping or suberect, simple or slightly branched, flexuose,
farm, sometimes thick and fleshy, cortical cells 15-25, similar to
the inner, sometimes brown, sometimes hyaline 8-10 in diameter •
radiculose, rootlets few, pellnoid. Leaves distant or approximate!
near the apex of fertile branches crowded, broader than the stem!
patent-divergent, below conoave-oomplioate or spreading, above
widely spreading or almo.st squarrose. oval-quadrate.‘bifid to
nearly the middle, sinus acute or obtusate, segments 5, 6 cells
wide at the base, acute or obtusate, divergent or erect ; cells small
4-, 5- and 6-angled, snbquadrate, walls firm, no trigones. Stipules
distinct on some stems, lanceolate-acute, sometimes above (sub-
bracteoles ?), bifid, sometimes minute or wanting. Flowers ? on
apex of main stem or on long or short branches. Bracts much
larger than the stem leaves, ovate-quadrate, bifid to about i siims
broad, acute or obtusate, segments narrowly triangular, acute,
dentate ; bracteole smaller than the bracts, oval or ovate, bifid tc!
about -j-. or ovate-lanoeolate and entire, margin dentate or denticu
late ; sub-bracts somewhat similar to the leaves but larger denticulate
or quite entire; sub-bracteole bidentate or entire, martin
dentionlate or quite entire. Perianth projecting much beyond the
bracts, large in proportion to the size of the plant, oblono- or
elongate-fusiform, iinistratose. trigonous, angles acute, mouth
liyaline, soariose and indistinctly crenulate. Pistillidia about 10.
