SEM and light microscopic studies in seeds of Hibiscus surattensis L. and phylogenetic attributes in Puducherry region, India

The micro-morphological and scanning electron microscopic (SEM) studies in seeds of Hibiscus surattensis L. has brought out five interesting as well as taxonomically and phylogenetic important traits for the first time. Hibiscus surattensis L. belongs to the family Malvaceae, located at Puducherry r...
