CLADOPHORA UNCIALIS, Harv.
G e n . Ch a r . Filaments green, jomted, uniform, branched. F m it
gated granules or zoospores, contained in the joints, having at some
period, a proper ciliary motion. Cladophora [Kiitz.]— b om kXuSos,

Cladophoea uneialis : tufts very short, spongy, simple below, above divided
into numerous fastigiate, woolly segments; filaments flexuous, sparingly
branched, densely interwoven ; ramuli distant, secund, long, patent,
or incurved; articulations about twice as long as broad.

De sc r . Filaments vei-y slender, an inch or two in length, densely aggregated
into spongy or rope-Kke tufts, forming a more or less definite compound
frond, which is simple below and divided into several branches of about
equal length, whose tops, therefore, standing on a level, produce a globular
tuft. As the plant advances in age, the branches become less regular, and
the tufts assume a woolly or shaggy aspect. Filaments irregularly and distantly
branched, interwoven, and connected together by root-like fibres,
which issue from the sides of the branches, take a downward direction, and
coil round neighbouring filaments; branches curved, secund, simple, or
with a few erect or subpatent, simple ramuli. Articulations pretty uniform,
generally about twice as long as broad, filled with a fluid endochrome.
Colour, a vivid green, discharged in fresh water, and very much faded in
diying. Suhstance membranaceous, adhering to paper.

This plant was added to the British Flora by Mrs. Griffiths in
the year 1833, and has been found abundantly in several places.
It more nearly resembles C. lanosa than any other of our native
species, and sometimes cannot be readily distinguished without
a close examination; but it forms much more dense and spongy
tufts, which finally become more intricately interwoven together;
