flexuous, pale-brown. Shoots i to 3 inches
simple, appearing branched by the growth of inno-’

of rootlets, which latter are rare on the erect shoots
Leaves smaller at the base, rather distant, obovate'
or obcordate, bilobed, lobes equal, sinus narrow’
margin plane, or undulate, inflexed at the base.
Textuie thin and tender, pale pellucid olive when

kertile stem thickened at apex. Involucral leaves
aiger than the rest, spreading, cordate, deeply
lobed Invo ucre of two convolute leaves, connate
at the lower third, lobes acute, inflexed. Perianth
with the apex free, divided into four or five broad
segments shorter than the involucre. Calyptra
campanulate pistillidia attached to the walls.

In boggy places, Scotch Highlands.
Stems two to four lines high, by a line in
breadth, of a brownish colour, slender, rigid,
flexuose, of a dense texture, naked, or a few scanty
white rootlets. Barren shoots 2 to 4 inches high,
simple, or with occasional innovations from the
axils of amphigastria. Leaves nearly uniform,
subvertically imbricate, appressed, obliquely orbicular,
or reniform, entire, or obscurely truncate,
very concave, ventral border rounded, and inserted
at right angles to the stem, anterior narrow and
decurrent. Colour uniform straw, or pale olive
green. Amphigastria rare, except at apex of young
shoots, long and slender, subulate, erect. Inflorescence
dioicous. Andrsecium spicate, terminal.
Perigonial leaves more rounded and convex,
gibbous at the base, posterior lobe subquadrate, inflexed.
Antheridia two to three in each leaf, round,
or obovate.
A t first sight resembling TV. compressa, but quite
distinct, which is supported by the cell structure.—
