ULTRASTRUCTURE OF SPONGIOCHLORIS TYPICA DURING SENESCENCE(1) (2).

abstract：:A previously unknown species of kelp was collected on Kagamil Island, Aleutian Islands. The species can be easily distinguished from any known laminarialean alga: the erect sporophytic thallus is composed of a thin lanceolate blade attaining ∼2 m in height and ∼0.50 m in width, without midrib, and the edge of the blad...
