This remarkable plant resembles, to the naked eye, Dictgosiphon foenicdacem-, but its stem and branches arc
solid thi-oughont, and the seeds are immersed endwise, in the substance of the branch.

Wc have seen no specimens of this, but what were dredged np from a considerable depth ; and. if fuRy grown,
the outline of the frond alone is sufflcient to distinguish it from its congeners.

pinporting that this species was also found in the Ealkland Islands.

This plant varies considerably at several periods of the year, becommg bare of ramuli in tho winter. I t is
abimdant in the German Ooean and on the Atlantic shores of Emope, and extra tropical North America, in the
Mediterranean Sea and Canaiy Islands, but has not been hitherto found within the Tropics. We regard these
specimens as specifically identical with others of British growth.

Apparently a mnch more widely distributed species than the former, ranging from the Baltic Sea and German
Ocean to the MeditciTancan and Canary Islands, also along the shores of the United States. In the Southern
hemisphere it has been found at the Cape of Good Hope and New Zealand.
