the extremities. : : 
The fructifications appear in every part of the plant, ex- 
cept the terminating segments. ‘They assume the shape of ob- 
long spots, placed at pretty regular intervals, of a darker co- 
lour than the rest of the plant. These spots under the micro. 
scope, are found to consist of dark red granules, or globules; 
smooth and without any fruit-stalk. i is 
First discovered by Mr. Srackxuousz, on the sands at 
Weymouth, very near the pier, at low water mark. 
Mr. Stackhouse observes, that a plant of this size and 
singularity must have attracted notice if common. Fe there- 
fore conjectures that it must be an inhabitant of deep waters, . 
fortuitously thrown ashore in a state of perfection. Sept. 1792.
