Morphological and anatomical studies on glycosmis perakensis V.Naray (Rutaceae)

There are a number of underexplored plant species from the family of Rutaceae despite their economic importance, including Glycosmis perakensis V.Naray. Therefore, the main purpose of this study is to enhance its taxonomic characterization and identification of this plant species by examining the mo...
