Comparison of morphological and anatomical characteristics of Syzygium nervosum A.Cunn. ex DC. and Syzygium samarangense (Blume) Merr. & L.M.Perry belonging to the genus Syzygium- family Myrtaceae

Abstract

     Two species "Voi" ( Syzygium nervosum) and "Man" ( Syzygium samarangense ) belonging to the Sim family (Myrtaceae), collected in Ho Chi Minh City, were described and compared in detail in terms of morphological characteristics, microscopic structure and analysis of medicinal properties. Research methods include analysis, description, photography, and use of optical microscopy techniques. The results of anatomical analysis of roots, stems and leaves show clear differences in the structure of the conducting tissue system in root microanatomy. The difference between the two species is also shown in the structural shape of the conducting tissue in the leaves and petioles between the two species Voi and Man. From the results obtained on morphological and anatomical characteristics, both species show distinct macroscopic and microscopic characteristics. Noticing these differences can be used to distinguish and identify close relationships between plant species, and provides an important database for the study of plant species.
