Comparison of morphological and anatomical characteristics of Hibiscus mutabilis L. and Hibiscus schizopetalus Hook.f., which belong to the genus Hibiscus- Cotton family (Malvaceae)

Abstract

    Two species (Hibiscus mutabilis L.) and (Hibiscus schizopetalus Hook.f.) collected in Ho Chi Minh City, have been described and compared in terms of morphological characteristics, anatomical structure analysis and medicinal powder examination for the purpose of supplementing additional data for species of the genus Hibiscus in Viet Nam. 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.
