N o t very rare on fubmarine rocks and ftones; nor is it
unfrequently call up on the fea beach in various parts of
England and Scotland. Lightfoot mentions never having
feen the fruit; but vie have found it on the Leith fhore, and
Mr. Dillwyn has favoured us with fine fpecimens, laden with
fruftification, from Dover.
The brilliant rofe-colour of this Fucus, and its delicately
waved and veined leaves, render it a beautiful and generally
attractive objeCt. The fhort branched Hem is fixed by a fwell-
ing to the rocks; the leaves vary in length from 3 to i t
inches; their form is elliptical, obtufe; their fubftance membranous,
elegantly waved and plaited; their margin entire.
A ftrong rib continued from the Item runs through the leaf,
producing at right angles many ftraight, parallel, lateral ribs
or veins. The capfules grow on fhort ftalks from the midrib
of an old leaf, and are globular, pointed, containing a round
mafs of dark-coloured feeds.—Ray’s comparifon of the leaves
to thofe of Rumex fanguineus is not unapt, however different
the colour may be.
