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. —

charinus, Linn. — Turn. Syn. Fuc. p. 198, Hist. Fuc. t. 163 j(3. 



bidlata; frond bullate in the centre, the margins waved. Turn. 

 — F. sacchar., E. Bot. t. 1376. — y. latifolia; stipes short cylin- 

 drical expanding into an ovato-elliptical submembranaceous 

 undivided frond. F. sacchar. var. latissima, Turn. — Laminaria 

 latifolia, Ag. Syst. Alg. v. I. p. 119. Grev. Alg. Brit. p. 31. —

Abundant on all the shores of Britain. — /3. Scotland. — y. Among re- 

 jectamenta 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 re- 

 sembling 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. 

 Sp. Alg. v. 1. p. 121. Grev. Alg. Brit. p. 34. — L. saccharina 

 var. attenuata, Grev. Fl. Edin. p. 282. — Fucus Phyllitis, 

 Stackh. Ner. Brit. — Turn. Syn. Fuc. p. 193, Hist. Fuc. t. 164. 

 E. Bot. t. 1331. 



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 dis- 

 tinguished 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. 

 Alg. 1. p. 120. Grev. Alg. Brit. p. 35. t. 5. — L. papyrina, 

 Bory.
