My figure 2, pi. xxxviii. is from the lower portion of the stem.
In Hooker’s “ Brit. Jung.,” pi. 65, f. 3, is a drawing of the
upper portion of a stem and branches, witli a perianth of the
true B. ciliaris.
Blepharozia pulcherrima (Hoffm.) differs from tliis species in
its smaller size, more procumbent habit, stems irregularly
dichotomously branched, leaves more finely ciliate, never with
segments entire on the stem-leaves, perianth cylindrical.
Blepharozia ciliaris is a very beautiful species, and not to
be confounded with any other, the nearest approach to it of our
British ones being Mastiyophora Woodsii (Hook.), which difiers in
the margin of the leaves being laciniate, not ciliate, in its bifid
stipules, which also are only spinose-dentate, not ciliate, and in
the very different cell structure. Trichocolea tomcntella (Ehrh.)
was confounded by some of the older botanists with this species,
to which it has a superficial resemblance, but apart from the
differences at once revealed by the microscope, it is readily
distinguished by its pale green colour, whilst B. ciliaris has a,
greenish to purplish-brown, or rich yellow.

Dioicous, cæspitose, small, tawny or brownish-green in colour.
Stems procumbent or rarely suberect, irregularly repeatedly
dichotomously ramose, branches ascending, cortical cells about 20,
walls golden-brown, inner hyaline 8 x 10, slightly frontally
compressed. Leaves crowded, patent, inouhous, imbrioate, con-
duplicate, semirotund, trifid or quadrifid to about a third or
more, segments broadly lanceolate subulate, margin and segments
with long cilia, cells medium size, roundish, walls thick, angles
thickened. Stipules about half the size of the leaves, semirotund,
bifid to about a fourth, margin with long cilia. Bracts roundish-
oblong-quadrate, trifid to about a third, segments lanceolate
subulate, margin and segments with long cilia; bracteole ovate,
bifid to about a fifth, margin and segments with long cilia.
Perianth terminal on main stem or branches, projecting about
two-thirds beyond the bracts, cylindrical, composed of a single
layer of cells, about 100 round the middle, slightly obtusely
trigonous, moutli contracted, ciliate, cilia 3 cells long, few. Pistillidia
numerous, linear-lanceolate. Androecia terminal or situated
on the middle of the branches, perigonial bracts 4-6, small,
closely imbricate, saccate at the base, subrotund, bifid to below the
middle, margin and segments ciliate, antheridia oval, large.

O b s . Distinguished from Blepiharozia ciliaris (L.) by its smaller
size, more procumbent habit, brownish-green colour (never rose or
purple), its irregularly dichotomous spreading branches, not gracefully
plumose and regularly bipinnate, its crowded, much more
ciliated stem leaves, segments never entire, and cylindrical
perianth, not oblong obovate.
