CRYPTOGAMIA. ALGiE. Fucus. 
numerous, alternate, divided and subdivided in various directions, and 
ultimately ending in a fork. Amongst the smaller branches and on the 
stem, are numerous teeth, simple or forked, various in their size, so as 
to give a fringed appearance to the plant. The swelling of these teeth 
would seem to indicate that they perform the office of fructification.

v. 3— F. baccatus . Gmel. E. Bot. E.) Rocks and stones in the sea, but 
rather scarce. P. Jan.—Dec. 
(F. ericoi'des. Stem ligneous, cylindrical, short, naked, its apex beset 
with long cartilaginous variously divided branches : bearing to¬ 
ward their extremities vesicles and fruit, clothed all over with 
subulate, mostly simple, erecto-patent, imbricated ramuli: vesi¬ 
cles roundish, innate, generally solitary : receptacles cylindrical, 
imbedded in the turgid apices of the branches. Turner.

The imbedded air-bladders contain filaments stretched across, analagous 
to the bladders in other Fuel. Fructification very visible in a slice cut 
out from the end of the branches. Whole plant horny to the touch, and 
almost prickly. Mr Stackhouse. 
This Fucus is found on sub-marine rocks at very low water, and is readily 
discovered by the bright glaucous tints which are reflected from it. It 
dries black, but if well preserved will retain on its upper branches a 
mixture of muddy green colour, from whence those beautiful tints origi¬ 
nate in its natural state. Major Velley. From two to four inches high ; 
bushy or rather tree-like in its growth. (. Leaves alternate, in pairs, awl- 
shaped.

F. fibro'sus. Thread-shaped, very much branched: bladders oval, 
in the substance of the plant: leafits thread-shaped and strap¬ 
shaped. Huds. 575.

From six to eighteen inches high. Stem knotty, rather strong; much 
branched. Bladders oval, rather pointed at each end; from the upper 
end of each proceeds numerous capillary cylindrical branches, which ex¬ 
tend several inches beyond the bladders and terminate the plant. Mr. 
Stackhouse. 
(Fibrous Knotty Fucus. E.) Sea shore. Yorkshire, Lancashire, and 
Hampshire. Cornish coast, common; (and Yarmouth. Dawson Turner, 
Esq. E.) Jan.—Dec. 
(F. barba'tus. E.) Thread-shaped; very much branched: bladders 
egg-shaped; terminated with leafits divided into many blunt 
segments, granulated at the ends. 
(Stem covered with elliptical knobs; branches filiform, repeatedly pinnated; 
spines few, scattered; tubercles collected into a solitary, lanceolate, ter¬ 
minal receptacle. Turn.
