CRYPTOGAMIA. ALGM. Fucus. 
Mr. Stackhouse observes, that a plant of this size and singularity must have 
attracted notice if common. He therefore conjectures that it must be an 
inhabitant of deep waters, fortuitously thrown ashore in a state of perfec¬ 
tion. Sept. 1792. 
This plant bears real tubercles, exactly resembling the fructification of 
F. laceratus. Turn. Hist. We learn from Mr. Turner that it has since 
been found on the coast of Cornwall; by Mrs. Griffiths at Swansea; by 
Mr. Dillwyn at Larne; near Belfast by Mr. Drummond; and in Bantry 
Bay by Miss Hutchins. E.) 
F. ligula'tus. Flat, membranaceous,, ribless,, strap-shaped, doubly 
winged: wings sword-shaped, fringed. 
{Turn. Hist. 98— E. Bat. 1636. E.)— Lightf. 29. at p. 946. 
Leaf one and a half to two feet long, about two lines broad, egg-shaped, 
herbaceous; serratures sometimes bristle-shaped. Huds. n. 32. There 
is a bulbous excrescence at the root, above which it generally breaks off. 
Fructifications on the stem, near the setting on of the leaves, resembling 
the saucers of a Lichen. Mr. Stackhouse. Plant green, thin and transpa¬ 
rent. The main stem about the breadth of a straw. The younger plants 
much like the feathered part of a large quill. 
(Green Strap-leaved Fucus. E.) F. herhaceus. Huds. 582. Frith of Forth, 
about New Haven and other places. Lightf. Rocks and stones in the 
sea. Thrown on the shore near Hastings, Sussex, and in Northumber¬ 
land. Huds. Yarmouth shore. Mr. Woodward. Cornish coast, com¬ 
mon. Stackhouse. (Bantry Bay, plentifully. Miss Hutchins. Turn. 
Hist. E.) 
F. denta'tus. Membranaceous, ribless: leaves wing-cleft; segments 
alternate, bluntly toothed.

Red; diaphanous; hollows of the clefts rounded. (The proper fructifi¬ 
cation consists of axillary clusters of pointed pods, each containing two 
rows of numerous seed-bearing tubercles. On some specimens are tuber¬ 
cles of a different kind not yet understood. Plant reddish-brown.

Not F. corymbiferus of Gmelin, as many botanists have suspected. That is 
a large plant, growing a foot high or more; this rarely exceeds five or 
six inches. Ends of the branches divided into acute segments. A faint 
nerve sometimes distinguishable in the branches. Linn. Tr. iii. 159.

stones in the sea. Devonshire and Yorkshire. (In Ireland and Scotland.

F. laciniMtus. Nearly stemless: leaves flat, membranaceous, without 
a mid-rib; branched: branches widening, hand-shaped. 
{Turn. Hist. 69— E. Bot. 1068. E.) 
Membranaceous, firm, pellucid, of a fine red colour. Leaf without a mid¬ 
rib, branched, branches mostly forked. Three to four inches long, four 
or five broad, but a single division about one inch broad. Sides and ends 
of the branches fringed and toothed. Secondary leaves only about a line 
in breadth. Gmelin. 
Var. 1. Edges fringed.
