Obs —This species is distinguished from Jung, saxicola by its
smaller cells, in addition to the other characters mentioned under
that species. In its sterile state it may be confounded with some
forms of Marsupella emarginata or Marsupella Funckii, but if bracts
be found it is at once identified.

Dioicous, growing in thick patches or amongst mosses, medium
to largish size, of a brown, yellowish, red-brown, or rarely of an
olive-green colour. Stems simple or furcate, somewhat robust,
firm, branches proceeding from below the leaves, suh-postioal,
between lateral and postical, but more postical; about 15 cells in
diam. ; cortical cells dark and firm, about 40 to 50 cells round,
inner white, somewhat firm and distinct, walls firm ; radiculose,
rootlets long, close, hyaline, some stems destitute. Leaves horizontally
inserted, equitant, imbricate or contiguous, regular, almost
of equal size, somewhat oblique, amjilexicaul, not deourrent, sub-
conduplicate, broadly ovate, bifid to the middle, rarely trifid, lobes
unequal, antioal a little smaller than the postical, segments subacute,
obtuse or roundish, margin quite entire ; cells smallish,
roundish, roundish-oblong or subquadrate, cell walls thick, angles
thickened. No stipules. Bracts larger than the leaves, 2 to 4-
lohed to near the middle, segments acute, dentate. Bracteole
bifid to below the middle, segments acute, dentate ; sub-bracts
broadly ovate or subquadrate, bifid to about the middle, segments
roundish, irregularly dentate ; sub-braoteole very small, obovate,
entire, or retuse. Perianth projecting about half beyond the
