On the sea-shore and in ditches and pools, both of salt and fresh
water, frequent. . Spring, Summer.—" Fronds closely aggregated,
swelling from a slender, filiform base to several lines in diameter rounded,
inflated, and puckered in various ways, a foot or more in length, of
a membranous structure, and pale-green colour. The var. crispa generally
grows solitary, attaining the length of 5— 6 feet, and upwards of 2
inches in diameter. It decays gradually from the extremity downward,
and on the edge of the decayed part, the granules are easily discernible,
very minute, and with little or no interval between them." Carm.

On various substances in the sea, abundant. 0. Spring—Autumn.
« Fronds gregarious or tufted, from 6 inches to 3 feet or more in
length, and from half a line to two inches in diameter, compressed or
collapsed and wrinkled, almost naked, or sending off innumerable long
slender simple branches chiefly from the margin. I am much inclined
to the opinion expressed in the Flora Scotica of Dr. Hooker, that S.
intestinalis is merely one of the numerous forms which this very variable
species assumes, and which run so insensibly into each other, that any
attempt to arrange them into varieties would prove equally difficult and
useless." Carm. MSS.
4. E. Linkidna, Grev. (Link's Enteromorphd) ; frond cylin-
drical tubular filiform reticulated pellucid of a very pale
green colour membranaceous (rigid when dry) much branched,
branches attenuated. Grev. Alg. Brit. p. 182.
In the sea ; on the coast of Appin, Captain Carmichael. © . Summer.
—The specimens of this in Captain CarmichaePs Herbarium do not
appear to me to differ from a not unfrequent state of E. compressa, except
in being a little more rigid than is usual with that species.
5. E. erecta, (erect Enteromorpha); fronds latticed filiform
tender, the branches and branchlets attenuated erect free. Carm.
