Sea-shore, in deep water. 14.—Very variable in the outline of its
frond, which when young is, like the last species, quite entire, and of so
large a size that Mrs. Griffiths measured one which formed a circle of at
least twelve feet in diameter. Grev.
3. L. saccharina, Lamour. (sugary Laminaria); root fibrous
long and branching, stipes cylindrical expanding at its apex in-
to a cartilaginous flat linear- oblong attenuated entire frond.

Abundant on all the shores of Britain.— /3. Scotland. y. Among rejectamenta
at Yarmouth, Mr. Mason. Firth of Forth and Isle of Bute.
Dr. Greville. $ ?— This well known plant attains a length of many feet
and derives its specific name from its being, after having been steeped in
fresh water and exposed to the sun, covered with a white efflorescence resembling
sugar, but nauseous to the taste. It is not the "saccharine Fucus"
of the Icelanders, as has been generally supposed: nor do I think it is
eaten at all by the natives of that country. It is said, however, to be
eaten in England by the poor, boiled as a potherb; but I know not
whether this has been asserted by any person besides Pallas. Thunberg
tells us, that in Japan it is prepared in such a manner as to be quite
esculent, and that it is customary there, when presents are made, to lay
upon them a slice of this Fucus attached to a piece of paper folded in a
curious manner, and tied with threads of gold or silver. Cattle eat it
not unfrequently. The var. y., Dr. Greville has, following Agardh, made
a distinct species ; not however without expressing his doubts as to the
propriety of so doing.
4. L. Phyllitis, Lamour. (thin-leaved Laminaria} ; root
fibrous branched, stipes somewhat compressed expanding at its
apex into a thin membranaceous linear-lanceolate frond. Ag.

On the stems of the larger marine Algee, in several parts of England,
Ireland and Scotland. $ .— The smaller size, thin and membranaceous
frond tapering at the base, are the characters by which this species is distinguished
from L. saccharina.
5. L. debilis, Ag. (delicate Laminaria} ; root minute scarcely
fibrous, stipes extremely short slender expanding into a broadly
oblong membranaceous frond cuneate at the base. Ag. Sp.
