Has. Attached to various substances in the sea, between tide-marks ; also 
in brackish and fresh-water ditches near the coast. Often floating. 
. Annual. Summer. Very common. 
Geoer. Distr. In similar situations, in most parts of the world. 
Descr. Root a minute, scutate disc. Frond froma few inches to one or more 
feet in length, and from a line to three or four inches, or more in diameter, 
tubular, obtuse, tapering at base to little more than the diameter of hog’s 
bristle, gradually becoming inflated upwards, and in old age often swelling 
out into a large membranous bag, which is variously crisped and curled. 
Sometimes the whole frond is compressed, and very much crisped. Sud- 
stance thin and membranous, but not gelatinous, not closely adhering to 
paper in drying. Colour varying from a transparent yellowish green, to a 
full grass-green ; in old age and decay fading to a dirty white. Under the 
microscope, a portion of the frond exhibits the appearance of a transparent 
membrane, covered with green, unequal, angular cells. 
A very common shore plant in all parts of the world, extending 
from the limits of vegetation in the Northern Hemisphere through 
all intervening latitudes to a similar pot in the south; and 
inhabiting not merely the sea, but brackish, or even fresh-water,
