CRYPTOGAMIA. ALGAE. Fucus. 
F. gigarti'nus. Cartilaginous; thread-shaped but compressed: forked: 
fructifications globular, on fruit stalks; those at the end with a 
thorn-shaped segment beyond them. 
{Turn. Hist. 28*— E. Bot. 908. E.)— Linn. Tr. iii. 17. 3. 4. E.) 
A hand’s breadth in height. Stiff, upright, pellucid, thread-shaped but 
compressed, coloured ; branches but few from the sides in proportion to 
the fructifications. Fructifications globular, about the size of rape seed, 
sessile on a short branch resembling a fruit-stalk, which sends out a little 
branch under the globule, and longer than it. Linn. Globules of fructi¬ 
fication dimpled at the point, which is probably the part destined for the 
escape of the seeds. Seeds egg-shaped; imbedded in a thick mucus, the 
colour of the pulp of a pomegranate. 
(Grape-seed Fucus. On the coast of Cornwall, originally found there by 
the Hon. Dr. Wenman of All Soul’s College, Oxford; and since by Dr. 
Macullock, in Mount’s Bay, near Newlyn. E.) 
F. granula/tus. Somewhat compressed, much branched: bulbs im¬ 
mersed but projecting from the lower part of the stem. (Stem 
covered with elliptical knobs; branches filiform, repeatedly pin¬ 
nated ; spines numerous, scattered; vesicles elliptical, innate, 
moniliform: tubercles either scattered over the branches, or 
collected into a lineari-subulate, terminal receptacle. Turn. E.) 
Stackh. ii. 11— {Turn. Hist. 251.— E. Bot. 2169. E.) 
About six inches high. Root discoid, shooting out immediately into nume¬ 
rous principal branches which have sometimes the fleshy bulb imbedded, 
at other times there are smaller conical roots at each side which send out 
branches. Upper parts of the plant much branched. Olive coloured 
when young, reddish when fully grown. The bulbs are evidently intended 
for one mode of propagation. When torn off by the waves, a branch 
from the principal stem often resembles an onion sprouting up. It is of 
a spongy soft texture, which added to the convenience of its imbricated 
bark for receiving seeds, causes it to be so infested with other Fuci, Con- 
fervse, &c. as to be quite overwhelmed, and it is also the favourite resi¬ 
dence of many zoophites. Stackhouse. (Varying so greatly in its cha¬ 
racteristics as to be denominated by Mr. Turner a Marine Proteus. It 
sometimes reflects glaucous prismatic tints, like F. ericoides , though in 
a less degree. E.) 
(Proteal Fucus. F. granulatus. Linn. E. Bot. F. foeniculaceus. Linn. 
Tr. (excl. syn. Linn.) F. nodicaulis. With, to Ed. 7. E.) On the coasts 
of Cornwall: at Penzance and at Acton Castle. (Bantry Bay. Miss 
Hutchins. E.) 
(F. acicula'ris. Frond pale red, somewhat cartilaginous, thread¬ 
shaped, repeatedly forked; its segments spreading, sharp- 
pointed, beset with scattered thorn-like processes; tubercles 
scattered, sessile, globular. 
Turn. Hist. 126— E. Bot. 2190. 
Several fronds two or three inches long, arise from one small callous base, 
occasionally somewhat flattened. Colour purplish red, white within.
