ANATOMICAL STUDIES OF LAURENCIA OBTUSA (HUDSON) LAMOUROUX (CERAMIALES) OF RHODOPHYCEAE

Thallus of Laurencia  obtusa  of Rhodophyceae was studied and detailed micromorphological  evaluation was done. Morphology of  the thallus  has been studied to aid pharmacognostic and phytochemical evidences to aid in taxonomic species identification. Parameters presented in this paper may be proposed to establish the authenticity of this red alga and can possibly help to differentiate this  alga from its other species. Since the collections were made in the month of March, Laurencia was with few gametophytic thalli . The study revealed several interesting anatomical characters and its cellular details
