350— R. Syn.2. 5. atp. 60. 
About five inches high, purple red. Stem depressed, very much branched, 
branches irregular, tiled; leafits doubly winged, with soft, undivided, 
crooked threads, thickest at the end, and with something of a jointed 
appearance. Gmelin, Fuc. p. 152. 
Resembles F. ahrotanifolius , but is winged like a Flypnum , and small. Linn. 
In its beautiful colour, its delicate texture, and its transparency, it 
agrees with F. coccineus , but differs from it in the ultimate leafits 
being placed regularly on each side the branches, whilst in the former 
they are only on one side, and generally three together. 
(Feathery Fucus. Ptilota plumosa. Turn. Hook. E.) Rocks and stones 
in the sea very common. P. Aug. —Oct. 
F. peduncula'tus. Gristly, thread-shaped, branched: branches bristle¬ 
shaped, bearing fruit, scattered: fructifications scattered, on fruit- 
stalks, oblong. Huds. 587- 
{Turn. Hist. 188.— E. Bot. 545. E.) 
Leaf nine inches long, semi-transparent, yellowish. Branches very simple,

(F. fruticulo'sus. Frond capillary, brown, bushy, obscurely jointed,

Surface reticulated with anastomosing veins ; ramuli bearing ovate, sessile 
capsules on their sides, and at their apices laceolate siliquie. Whole 
plant resembling a beautiful shrub, bright chocolate brown, black when 
dry. Turn. Hist. From one callous root arise many bushy fronds, about 
three inches high. E. Bot. There appears no sufficient reason for refer¬ 
ring this plant to Hudson’s Conferva nigra, though possibly it may ulti¬ 
mately be arranged with that genus. 
Little Shrubby Fucus. Dorsetshire, Devonshire, and Cornwall, usually 
found growing on the stems of the larger Fuci. A.—E.)
