CRYPTOGAMIA. ALG.E. Fucus. 
106 
(F. wig'ghii. Sub-gelatinous, cylindrical, filiform, much and irregu¬ 
larly branched, every where beset with setaceous, mostly simple, 
scattered ramuli, swelling in their centre into lanceolate capsules, 
and composed of branched, jointed fibres. 
Turn. Hist. 102— Linn. Tr. v. 6. t. x— E. Bot. 1184. 
Frond, from three to eight inches long, as thick at its origin as a blackbird’s 
quill, thence attenuated to a long acuminated point. Fructification on 
the ramuli which swell in their centre, of a darker colour than the rest of 
the frond. Colour a pale transparent pink; darker when dry; but if 
kept long turning to dirty yellowish white. Substance slippery and tender. 
Under a powerful microscope the surface of the frond appears reticulated 
with regular square meshes. The setaceous ramuli readily distinguish it 
from its congeners. 
Setaceous Jointed Fucus. This very rare and novel species was dis¬ 
covered by Mr. Lilly Wigg. It has been found occasionally on the 
Yarmouth beach among the rejectamenta of the sea. Bantry Bay, Miss 
Hutchins. Brighton, Mr. Borrer. One specimen at Folkstone, Miss 
Everett. Turn. Hist. E. A. July—Sept.) 
F. FiLdciNtrs. Leaves gristly, compressed, blunt, mostly triply winged; 
segments horizontal, blunt. Huds. Ed. 2. 586. 
(Fern-like Fucus. F. filicinus. Lightf. 955, is F. pinnatifidus.') Rocks 
and stones near Walney, Lancashire. A. May - Oct. 
It is not certainly known what plant Mr. Hudson here intended. Mr. 
Lightfoot considered it a variation of F. pinnatifidus , the plant being 
larger and the segments wider; but Dr. Goodenough has lately in¬ 
formed me that it is a variety of F. corneus. 
F. pinna'tus. Gristly, thread-shaped, compressed, generally triply 
winged ; segments awl-shaped, nearly upright. Huds. 586. 
Leaf three inches long, red, sometimes doubly winged, pointed; segments 
opposite, very short. LIuds. This stands entirely on the authority of 
Mr. Hudson. Dr. Goodenough thinks it can be nothing but F. corneus. 
(Winged Red Fucus. E.) Rocks and stones in the sea; Cornwall, Devon¬ 
shire, Sussex, and Scarborough. A. May—Oct. 
F . al/bidus. Gristly, thread-shaped, somewhat forked; branches 
brittle-shaped, distant, mostly pointing one way: fructifications 
lateral, roundish, sessile. Huds. 588. 
Jaccj. Coll. iii. 14. 1 —Gmel. 14. 1—( Turn. Hist. 842. E.) 
From two to twelve inches high or more. Stem cylindrical, cartilaginous, 
but tender, very pellucid, set with numerous small dots with a perforated 
appearance. Branchesfaom near the root; resembling the stem, nearly as 
thick, but very short; divisions and sub-divisions of the branches finer 
and finer. Branches often on one side, sometimes on both; sometimes 
forked, generally solitary. Warts or capsules, lateral, sessile, frequent, 
pellucid, solitary, or in pairs, distant or crowded, varying in size, open 
at the top. Gmelin, 136. 
(Mr. D. Turner suspects this may prove to be the same plant as F.con - 
feryoides of With. 
Bristly Whitish Fucus. E.) Rocks and stones in the sea. (At Cromer. 
Mr. Turner. E.) P. June—Oct.
