Tetrasporophytic Plant Polysiphonia is a heterotrichous alga having an erect series of branches and a filamentous prostrate section attached to the substratum by means of unicellular rhizoids. The ends of the rhizoids are flattened into lobed discs called haptera, which assist the penetration of the host tissue ( Polysiphonia parasitic form) or confirm attachment to substrata. Polysiphonia is a genus of filamentous red algae with about 19 species on the coasts of the British Isles and about 200 species worldwide, including Crete in Greece, Antarctica and Greenland.
