CRYPTOGAMIA. ALGiE. Ulva.

Inner surface of this membrane interspersed on every part with innume¬ 
rable minute specks, which at first give the whole plant the beautiful hue 
of the almond blossom ; but as the gelatinous substance diminishes, these 
granulated substances attain a kind of orange colour, and from the outer 
fine membrane collapsing upon them they become more distinct, appear¬ 
ing almost as if fixed on the outer surface. 
(Broken Laver. E.) Found not unfrequently at low water on the beach at 
Weymouth ; but I never could discover any root upon the various spe¬ 
cimens I have examined. As they adhere closely together, and are very 
tender, they are probably broken by the flux of the sea, and torn off from 
their base. Specimen and description from Major Velley. (Eastern 
coast of Scotland. James Brodie, Esq. in E. Bot. E.) 
U, elminthoi'des. Thread-shaped, entire, or but little branched, 
opake, slippery, and bluntish. 
Plate XVII. f. 2. 
Resembles a worm in its writhing form, size, and slimy nature. It rises 
from a thick, blunted base, like glue, fixed in the interstices of the 
rocks. It is generally simple, sometimes a little branched towards the 
middle of the plant, sometimes five or six grow together, in which case 
they are proportionably reduced in size, which in the largest seldom 
exceeds that of a goose quill; from four to seven inches long, blunt at 
the end. Colour resembling, but sometimes lighter than, that of glue. 
It is soft, and consists of a fine membrane, which on its internal surface 
seems crowded with extremely minute, opake, granulated bodies. If 
cut horizontally into very thin lamina, these grains appear fixed in a 
clear gelatinous substance, which constitutes the interior body of the 
plant, and they seem to occupy about one third part of its surface in a 
circular direction, leaving the middle part perfectly clear, through the 
centre of which a dark parenchymous line passes, from one extremity to 
the other. 
(Vermicular Laver. E.) Fucus ehninthoides. With. Ed. 2. Grows in 
abundance upon the rocks off the Beal, at the extremity of Portland, at 
very low water. June, July. I could not find it in October, so that I 
suppose, from its mucilaginous texture, it soon perishes. Major Velley. 
U. intestina'lis. Tubular, simple, equal, membranaceous, green. 
Dill. 9. 7— Buxb. v. 23. 1. 
Varying greatly in size ; simple or branched, from the thickness of a quill 
to that of a walking-stick, and an ell or two in length; hollow, very 
unequal on the surface, yellowish when young, changing to a fine green. 
Dill. 47. 
(Intestinal Laver. E.) Mostly in ditches near the sea, but sometimes 
in fresh water ditches. Very common in Cornwall, and of all sizes. The 
inside often filled with sand so as to represent a pig's pudding. Mr. 
Stackhouse. (In Jarrow Slake, and Coble Dean, oo the Tyne: and 
Pallion, on the Wear. Mr. Winch. E.) A. March—-Oct. 
U. fistulo'sa. Tubular, uniform, simple. Huds. 56’9* 
(F. Bot. 642. E.) 
Boot creeping. Leaves numerous, pipe-like, closed at the end, brownish, 
three inches long, of the thickness of shop pack-thread. Seeds numerous, 
small, round, brown. Huds. n. 13.
