MORPHO-ANATOMY OF STYPOPODIUM ZONALE (PHAEOPHYCOTA) FROM THE COAST OF KARACHI, PAKISTAN

Abstract

A brown alga Stypopodium zonale (Lamouroux) Papenfuss (Dictyotales) was collected from Manora and Buleji, the coastal areas near Karachi (Pakistan) during March 2006-April 2009 and investigated for its morphology, anatomy and reproductive structures. This is the first detailed study on the Pakistani specimens of this species from these points of view, where presence or absence of intercellular spaces, cell-wall thickness of different cells and structure of surface cells were examined. In this connection the apical, middle and basal parts of the thallus were investigated anatomically.
