Perhaps only a variety of C. afinis, but the habit is somewhat different, and the articulations difficult to be 
seen in any part of the frond, owing to the thickness of the outer walls. The plant grows on tidal nooks, in shal- 
lower water than L. affinis, and is generally, from exposure to sunlight, of a dull livid-green, tipped with purple.
