CLADOPHORA UNCIALIS, Zarv. 
Gen. Cuar. Filaments green, jointed, uniform, branched. Fruit aggre- 
gated granules or zoospores, contained in the joints, having at some 
period, a proper ciliary motion. CiapopHora (Av/z.)—from «dados, 
a branch, and popew, to bear. 
CrapopHora wacialis : 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.

Descr. Filaments very slender, an inch or two in length, densely aggregated 
into spongy or rope-like 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. Fi/aments irregularly and dis- 
tantly branched, interwoven, and connected together by root-lke fibres, 
which issue from the sides of the branches, take a downward direction, and 
coil round neighbouring filaments; éranches 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 
drying. Substance 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. /anosa 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 ;
