The correct identification of these species was carried out by methods of analysis, description, photography, and optical microscopy. The results of anatomical analysis of roots, stems, and leaves showed that these two species differed in the arrangement of wood vessels in the roots
The difference is also reflected in the arrangement of petioles and accessory conduction tissues in the midrib, as well as leaf blade structures of the 2 species (Hibiscus mutabilis L.) and (Hibiscus schizopetalus Hook.f.). From the results obtained the morphological and anatomical characteristics of both species of hibiscus, it is found that the macroscopic and microscopic characteristics are the analyzed and descriptive characteristics that can be used to differentiate and identify the hibiscus species. from closely related plant species and as a database for plant diversity.
