Heteroicous (monoicous and paroicous), cæspitose, medium
size, pale to dark-green in colour. Stems prostrate or suberect,
simple or furcate, attenuate often at the apex and gemmiparous ;
radiculose, rootlets plentiful, proceeding from the base of the
stipules. Leaves approximate or imbricate, horizontal or patent-
divergent, broadly ovate, apex entire, acute or rotundate or acutely
and shallowly bidentate, sinus and segments acute, margin entire ;
texture lax ; cells rather large, hexagonal or oblong-hexagonal,
walls thin, nucleate granules clinging to the walls making them
appear thicker, trigones very minute or absent. Stipules about a
fifth to a fourth smaller than the leaves, about twice as broad as
tlie stem, irregular in shape, suboblate to subreniform, bifid to
about a third, sinus wide, acute or obtuse, segments spreading
acute or obtusate, lobate, outer lobe smaller. Male and female
flowers proceeding from axil of stipules, sometimes the two proceeding
from the one axil. Perfect fruit and male flowers I have
not seen.

with leaves 2'5 mm. wide; leaves lA mm. x 1'2 mm., sinus

H a b .—Growing in patches on damp shady banks, in woods,
&o. Somewhat rare, probably often mistaken for Kantia Trichomanis.

O bs.—Distinguished from. K. Trichomanis (L.) by the laxer
texture of the leaves, the thinner cell-walls, stipules irregular in
shape, more deeply and acutely divided, segments spreading, often
acute and again lobate, outer lobe smaller.
I t may be considered by some authorities as only a variety of
K. Trichomanis, but as the distinguishing characters are always
permanent, I give it as a species.

Dioicous, laxly and thinly spreading, small, pale green in
colour. Stems simple or sparinglj' branched, delicate, sometimes
elongate, attenuate, depauperate,frequently gemmiparous; branches
proceeding from axil of stipules ; radiculose, rootlets few. Leaves
distant or approximate, largest near the middle of stem, smaller
below, and often near the apex minute and remote, horizontal to
patent-divergent, postical margin usually deourrent, oval or oblong-
oval, bidentate to about one-tenth, sinus broad, semilunate, segments
a little divergent, acute ; texture fragile, lax, cells rather
large, 4-, 5- and 6-sided, walls thick, no trigones. Stipules small,
scarcely twice as broad as the stem, irregular in shape, much
broader than long, bidentate to below the middle, segments divergent,
lobate to the middle or below, lobules acute, divergent.
I have seen no perfect 8 or Î ; the drawing of the perianth is
from a sketch sent me by Mr. Slater, who found a single one
on a plant collected by Mr. Curnow near Penzance. Andrcecia
on separate plants, bud-like, small, proceeding from axil of
stipules.
