CRYFT0GAM1A. ALGAL Fucus. 
(F. norve'gicus. (Frond cartilaginous, nerveless, dichotomous; branches 
linear, entire, rounded at their apices; tubercles hemispherical, 
sessile on the disk of the leaf. 
Turn. Hist. 41— E. Bot. 1080— Gun. Now. t. 34. 
Tubercles the size of a poppy-seed, of the same colour as the frond. Colour 
deep blood-red, somewhat tinged with brown, a beautiful transparent 
pink in the younger shoots, and sometimes at the apices; turning to a 
dirty yellowish colour. Substance cartilaginous, pliant, tough, ap¬ 
proaching to coriaceous in the older, and to membranaceous in the 
younger plants. Turn. Hist. 
Red Norway Fucus. This species was first made known by Bishop 
Gunner as a native of the coast of Norway. It has since been found at 
Hover by Mr. Dillwyn, at Exmouth plentifully by Sir T. Franldand, and 
still farther west by Mrs. Griffiths. Sept.—March. E.) 
F. fimbria'tus. ' Stem compressed, nearly simple: leaves pointing 
from two opposite lines, strap-shaped, fringed: fructifications 
along the edge, oblong. Huds. 574. 
Gmel. Fuc. 20. 2. 
A foot high or more; membranaceous, diaphanous, fine red, paler in places. 
Leaf winged. Leafits on very short leaf-stalks, lower ones the shortest, 
upper ones as much as four inches long; oblong-spear-shaped, sometimes 
proliferous, alternate or opposite, edges fringed with wedge-shaped sub¬ 
stances. Gmelin. Fuc. 173, who observes that it is a native of the Indian 
ocean. 
The figure of Gmelin quoted as above by Mr. Hudson for this plant, if it 
had a mid-rib would be a much better representation of F. rubens of 
English botanists than 24. 1. of the same author; I have never seen 
a specimen of Mr. Hudson’s F. fimbriatus, but suspect that he may have 
only had before him a large and perfect plant of F. rubens. 
(Fringed Red Fucus. E.) On the sea shore in Portland Island, but rare. 
P. Jan.—Dec. 
F. cris'pus. Membranaceous, forked; segments broader at the ends. 
Linn. 
( Turn. Hist. 216. 217— E. Bot. 2285. E.)— H. Ox. xv. 8. row 2. 6. 
Between cartilaginous and membranaceous; purple or whitish, broader 
upwards; at the ends bluntly toothed. Linn. From two to six inches 
high, the smaller specimens the broadest and the most membranaceous, 
the taller ones narrower and more cartilaginous. (Varying greatly in 
appearance, as Mrs. Griffiths observes in Turn. Hist. ofF 1 . crispus, every 
pool upon the Devonshire coast produces a dissimilar sort, and where 
there is any mixture of fresh water the varieties are monstrous as well as 
endless.” 
Crisped Fucus. Common on the British coasts. Sphcerococcus crispus. 
Agard. Hook. Not F. crispus of Hudson, which is F. rubens of Linn. 
Turn. E. Bot. &c. vid. F.membranifolius. E.) 
F. membranifo'eius. Cartilaginous, fiat, forked, narrow at the base, 
wider upwards: fructifications oval, horny imbedded tubercles, 
containing numerous seeds.
