Apoglossum Ruscifolium
''Apoglossum ruscifolium'' is a small red marine seaweed. Description ''Apoglossum ruscifolium'' has branched monostromic blades growing to 10 cm long.Maggs,C.A. and Hommersand, M.H.1993 ''Seaweeds of the British Isles Volume 1 Rhodophyta Part 3A Ceramiales.'' The Natural History Museum, London The axis branches with primary blades reaching 10 cm long and up to 0.8 cm wide, each with a clear midrib and pointed apices. Lateral veins are microscopic. The species is similar to '' Membranoptera alata'' and '' Hypoglossum hypoglossoides'' but can be clearly distinguished. The branches of ''H. hypoglossoides'' are clearly pointed and the young blades of ''M.alata'' are not pointed and are asymmetric with pincer-like tips. Reproduction Microscopic sori are formed are microscopic and are formed on either side of the midrib. Female cystocarps occur singly on the frond.Bunker, F.StP.D., Maggs, C.A., Brodie, J., Bunker, A.R. 2017 ''Seaweeds of Britain and Ireland.'' Second Edition. Wild ...

Membranoptera Alata
''Membranoptera alata'' is a small red alga in the Rhodophyta. Description ''Membranoptera alata'' is a small red marine alga growing to a length of no more than 20 cm. Its fronds are up to 2.4 mm wide and monostromatic, that is formed of a thin layer of cells,Maggs, C.A. and Hommersand, M.H. 1993. ''Seaweeds of the British Isles, Volume 1 Rhodopyta Part 3A Ceramiales.'' The Natural History Museum, London narrow and branching in one plane. A midrib runs along the center of the branches with fine microscopic veins from the midrib to the margins. The tips of the young branches are asymmetric, incurved and blunt, not pointed.Bunker, F.StP.D., Brodie, J.A., Maggs, C.A. and Bunker, A.R.2017 ''Seaweeds of Britain and Ireland. Second Edition''.

Hypoglossum Hypoglossoides
''Hypoglossum hypoglossoides'', known as under tongue weed, is a small red marine alga in the family Delesseriaceae. Description ''Hypoglossum hypoglossoides'' is a small red alga growing as monostromatic blades in tufts to a length of 30 cm and 0.8 cm wide. The lateral branches grow as blades which, like the primary blade, has a midrib. All the blades have a lanceolate or acute apices. All the blades lack lateral veins.

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now const ...
