A LONG known plant, the difference of whose structure
and consequent texture from that of every other seaweed,
has caused it to be shifted from one genus to another,
until Dr. Greville has at length, in his scientific
and beautifully illustrated work on British Algas, settled it
as the type of a new genus, of which at present another
species is not known. It appears to be limited to rather

found it on the shores of Cornwall; but it has generally
been collected farther north. Our specimen, which unfortunately
has neither root nor seeds, was collected many
years ago on the coast of Anglesea, by our lamented friend
