Cladophora fa lc a ta ; densely tufted, dark-green ; filaments 'intricate at
tbe base, ultra-capillary, rigid, much curved, irregularly branched;
branches zig-zag, repeatedly divided, the lesser divisions arched, or
strongly incurved and falcate, furnished along their inner faces with
short, secund, blunt ramuli ; articulations three or four times longer
than broad, with a dense endochrome, and pellucid dissepiments.

D esc r. Pilaments densely tufted, somewhat interwoven and entangled at the
base, three or four inches high, thicker than human hair, nearly of equal
diameter throughout, much branched and repeatedly divided. Branches
curved and twisted, or curled in various directions, irregularly divided ; the
lesser branches sometimes alternate, sometimes secund, and sometimes two
or three springing from the same point, ail veiy erect, arching or strongly
hooked inwards, furnished on their concave side with numerous secund
ramuli of miequal length, long and short occurring alternately, the shorter
ramuli simple, formed of one or two cells ; the longer bearing a second
series on their faces, and hooked Uke the branches. The aspect of the whole
tuft is peculiarly crisp and squarrose. Articulations tolerably uniform,
three or four times as long as broad, with hyaline borders and dissepiments,
and containing a dense endochrome, which partially recovers its form after
having been dried. Colour, a rich, glossy, fuU gi-een. Substance rigid and
crisp, adhering to paper in drying.
I gathered a few specimens of the Cladophora here figured in
the summer of 1845, in some deep rock-pools, near low-water
mark, under a steep mural cliff, in a situation where the fronds
were constantly in shade. More recently I have received from
Miss White specimens collected at Jersey, which agree in most
