cærulesoent. Stems creeping, horizontal, irregularly subpinnate
or sub-bipinnate, flexuose, on a oross-section 12 to 15 cells in diam.,
hyaline, cortical larger, about 30 ; branches all lateral, some
attenuate ; radiculose, rootlets numerous, near base of the plant,
fasciculate, hyaline. Leaves incubous, imbricate or subimbricate
on main stem, on branches, and attenuated branches small and
distant, patent or patent-divergent, convex, snbquadrate or semioval,
slightly longer than broad, quadri-dentate to about segments
acute, 4-7 cells broad at the base, sinus acute, apices
incurved, branch leaves tridentate, axillary leaves bidentate ; cells
medium size, subquadrate, often broader than long, subopaque,
walls thick, but somewhat delicate, no trigones or thickened angles.
Stipules about twice the width of the stem, very convex, subquadrate,
broader than long, quadrifid to about a third, on branches
trifid, segments acute. Bracts several pairs at the base of the
perianth, very delicate texture, subrotund or broadly oval, irregularly
dentate at the apex ; bracteole very delicate texture, oval or
broadly oval, irregularly dentate at the apex. Perianth produced
on very short postical branches, projecting f beyond the bracts,
almost hyaline, sub-membranaceous, lower half composed of two
layers of cells, upper half of a single layer, near the middle about
100 cells round, oblong-subulate, below cylindrical, above somewhat
plicate, mouth constricted, dentate, teeth about 8. Calyptra
large, oval, composed of one layer of cells. Pistillidia few, 4 or 5.
Capsule oblong-ovate, deep brown, splitting into 4 equal lanceolate
valves. Spores small, verruculose, reddish-brown. Elaters bispiral,
not quite as broad as the spores, reddish-brown. Androecia
postical, amentiform, catkins small, composed of 4-6 pairs of
perigonial bracts, which are minute, delicate, complicate, broadly
oval when explánate, bidentate to about a fourth ; perigonial bracteoles
oval, bidentate.

H a b .—Growing in dense tufts or straggling amongst mosses.
Common. 1 to 17. I. C.
Found on the Continent, and in North America.
O bs.—This is a common species; for its distinguishing
characters from L. ciipvessina and L. Pearsoni, see notes under
those species ; being monoicous it is easily recognised by this
character.

Lepidozia Wulfsbergii, Lindb. Soc. F. Fl. Fenn. 1882; Bot. not. (1882).
Dioicous, creeping, medium to largish in size, from pale to
tawny-green in colour. Stems suhterete, on a cross-section cells
15x18, cortical 40 to 50, a little larger; flaccid, very slender,
elongate, simple or furcate, afterwards laxly and distantly pinnate ;
branches short, unequal, simple, very rarely ramulose, some with
apices flagelliferous, microphyllous or radiculose; rootlets proceeding
more from the stem than from the flagella, or almost absent;
all branches more or less lateral, axillary, often with male flowers;
rarely a postical stolon is observed and sometimes postical amenti
