It is perennial and attached by a discoid holdfast, it grows in tufts, erect, firm and cartilaginous. All the axes and branches are compressed or flat with an inconspicuous central midrib. The lateral branches are short and are produced alternately from near the base, they are deeply toothed.[4]
Reproduction
[edit]The planta are perennial and the sexes are produced on separate plants, dioecious. Spermatangia are in small clusters at the apex of the frond. The female cystocarps are found in the axils of the axis. Tetrasporangia occur in pairs in branchlets.[5][4]
Habitat
[edit]Common on northern shores of Great Britain and Ireland in low littoral rock pools and in the sub-littoral to 20m. Also on the stipes of Laminaria.[4]
