AB The vegetative and reproductive morphology and the distributionin the Canary Islands of four Polysiphonia species from the section Polysiphonia(species with more of four pericentral cells) are examined. These species havea small number of pericentral cells (5-13): P. ceramiaeformis (11-13), P. denudata(5-7), P. furcellata (7-8) and P. tepida (7-8). P. ceramiaeformis is wellcharacterized by the number of pericentrales cells, P. denudata by its completelyerect habit and its radial ramification, P. furcellata by its erect habit and itsforcipate branches, and P. tepida by its entangled axes and abundant prostrateaxes. The specimens from the Canary Islands are in agreement with previousdescriptions of these species, but they exhibit reduced dimensions. Canarianpopulations of P. denudata have fertile specimens, both gametophytes andtetrasporophytes. Whereas populations of P. tepida have only tetrasporophytesand female gametophytes, in P. ceramiaeformis populations tetrasporophyteswere only present, and in P. furcellata populations only sterile specimensoccurred.
