X H E fpecimen here delineated was gathered by Mr. D.
Turner on the rocks at Sheringham, Norfolk: fee his Synopjis,
Pa§e 3*8. On the fea-fhore this Fucus is frequently caft up,
and confifts of thick, matted, wiry tufts, varying from deep
brownith purple to pale pink, yellow, or a waxy white; to the
latter perhaps it is reduced by the action of the air and light.
The root, with which we have been hitherto unacquainted,
is a fmall expanded difk. Fronds numerous, much branched,
in a Angularly irregular and cluftered manner; all the branches
of each clufter moftly leaning one way : the whole frond
and branches are thread-thaped, and nearly of an equal thick-
nefs throughout. Fruftification of numerous, fmall, dark,
prominent tubercles, fcattered over the branches, and often
terminating them.
