capsules immersed iu the substance of tlie extremity of the ramuli,
containing a mass of minute ovate or oblong seeds, apparently mixed
with some filaments ; 2. ternate granules imbedded in the ramuli, in
distinct individuals. The common, or, if we may make use of the
expression, the proper form of the plant, is that indicated in the specific
character : the height of the frond is two or three inches, its width
about half a line in the main stem : it is between compressed and
plane, rising with a simple or divided stem, the branches sometimes
naked below, but often pinnated along their whole length at intervals
of about a line : pinnæ either horizontal or spreading, narrower than
the branches, varying in length on the same specimen from a few lines
to two inches, attenuated at their base, obtuse at the apex, bearing
one or two series of pinnulæ, similar to the pinnæ, except in being
sliorter and finer, and, like them, decreasing in length as they approach
the summit.
The varieties of this species are almost endless, and some of them
so singular, that, without practical knowledge to guide us in our investigation,
they might be taken for very distinct species.
Var. g sesqiiipedalis ; frond long between compressed and flat
linear tripinnate pinnæ attenuated at their base, ramuli linear oblong
short obtuse.

Frond four to eight inches high, pinnated from near the base; the
ultimate ramuli much attenuated at their insertion, one or two lines
long, rounded at the apex, often contracted so as to appear proliferous.

nearly linear bluntish. Turn.

H a b . Coasts of Cornwall, Devonshire, and Sussex, everywhere, and
at Scarborough, Hudson. Exmouth, Goodenough. Isle of Bute.
Frond two to six inches high, narrow, cartilaginous ra th e r than
homy, th e branches naiTow, the pinnæ nearly linear or slightly dilated
upwards with an elliptical apex.
Var. â uniforme ; all the pinnæ patent, attenuated at the base, obtuse
at the points and scattered.

This variety has not come under my own observation.
Var. £ capillaceum ; frond narrow, pinnæ clustered towards its
summits, nearly setaceous and somewhat erect. Turn.

H ab . King’s Cove, Cornwall, Turner. Rocks at the base of Peakhead,
near Sidmouth.
In my specimens the frond is six inches high, the greater part of
the stem naked, and the pinnæ given oflF at the top, almost in the form
of an umbel.
Var. Ç latifolium ; frond broad nearly flat, pinnæ linear-lanceolate
mostly simple set with numerous short setaceous pinnulæ.
H a b . Trevone Bay, Cornwall, and Waldon rocks, Torbay, Mrs
Griffiths. Sidmouth and Torquay.
A very beautiful variety, that I do not find clearly indicated by
Turner or Agardh. Frond two to three inches long, simple or slightly
branched, one to near two lines broad ; pinnæ linear lanceolate, a line
broad in the widest part, attenuated at the extremity, and either obtuse
or lengthened out into a setaceous point ; pinnulæ very numerous,
setaceous, two or three lines long, nearly horizontal, simple or bearing
a few minute ramuli. Fructification is very common on this variety,
the capsules swelling the ends of the pinnulæ, or often rising at once
from the pinnæ, intermixed with the pinnulæ, and supported upon a
minute peduncle. This plant comes nearest to Fig. b. in Mr Turner’s
Plate.
Var. n corfertum ; frond compressed repeatedly pinnated, pinnæ
and pinnulæ long very thin acute and irregularly divided.
Fucus corneus, v a r . confertus. T u r n . H i s t . F u c . v . 4. p . 146.
H a b . Paignton, Devonshire, Mrs Griffiths. Black Rocks, near
Bamborough. Isle of Bute.
Frond entangled, two or three inches high, of a yellowish red or
amber colour, so slender as to be sometimes almost capillary.
Var. A aculeatum ; frond compressed very thin pinnated very irregularly,
pinnæ divaricated irregularly divided and set with minute
