surface of the frond. How far the plant called Fucus ruscifolius in Turn. 
Hist. 15. and E. Bot. 1395. is really to be specifically distinguished by 
its chain-like veins from F. hypoglossum we still doubt. 
Sharp Tongue-bearing Fucus. On marine rocks near Scarborough, 
but very rare. Mr. Travis. Near Sunderland. Mr. J. Hobson. E.) 
Found by Mr. Wigg on the beach at Yarmouth, by Mr. Crowe at Cromer, 
and by Dr. Goodenough on the southern coast. 
F. alaHus. Membranaceous; somewhat forked; mid-ribbed; seg¬ 
ments alternate, decurrent, cloven. Linn. Leaves very entire, 
coloured. Huds. Ed. 1. 473. Ed. 2. 578.

younger state ; 3, a variety with broader leaves. 
Leaves branched, purple, diaphanous, strap-shaped, ends some what'toothed, 
mid-rib rather thick. Linn. Three inches long Or more, membranaceous, 
thin. Stem flatted, one line broad, very much branched. Branches alter¬ 
nate, edged with a thin leafy substance. Gmelin Fuc. 187. Rose 
colour or pink ; forked; consisting of a mid-rib garnished on each side 
with a transparent and very narroiv membrane. Mr. Stackhouse. When 
the leafy membranaceous substance which edges the rib of the branches 
decays or rubs off, the plant assumes a very different appearance, seeming 
then to be composed of thread-shaped branches. 
(Winged Crimson Fucus. Delessaria alata. Agard. Hook. E.) Sea 
rocks or stones. On the large stalks of F. polysehides and digitatus. Mr. 
Stackhouse. (At Lossie-mouth, on the north-east coast of Scotland. 
Mr. Brodie. On the southern and western shores of England and 
Ireland, not uncommon. Turn. Flist. E.) P. May.—Oct.

Tali, forked, strap-shaped, compressed: set with raised, blunt tubercles. 
Linn. This plant at its first appearance so much resembles a Fungus, 
that some authors have mistaken it for one. Ray seems to have described 
it as a distinct species under the name of “ Fucus Fungis affinis.” Syn. 
p. 43. n. 15. From the centre of the little Fungus-like substance three 
or four shoots arise, and extending by degrees, into branches, constitute 
the perfect plant. The little Fungus still continues and forms a kind of 
cup at the base of the stem. 
Grows to a great length, and is more regularly forked than any other plant I 
know. It grows fixed to the rocks by a most tenacious gluten. Major 
Velley. A short stem supports a kind of cup full half an inch diameter. 
Out of this arise one or two strap-shaped leaves, several feet in length, 
nearly as-.broad as a straw, dividing into forks at distant intervals. The 
whole plant is opake, ribless, dark-coloured, and in every part beset with 
tubercles filled with a slimy fluid, and open at the top. A pencil of hairs 
issues from some of them, but the fluid they pour out contains nothing 
like seeds ; the others without hairs pour out a mucilage filled with seeds 
of an oblong shape, but so small as to elude the naked eye. This appa¬ 
ratus of fructification seems nearly the same as that in F. serraius, except 
that in this plant the male and female organs are indiscriminately dis¬ 
persed over the whole plant, whilst in that the male flowers are on the
