  ABSTRACT: The relationship between six Abutilon species was examined using different taxonomic investigation tools. The investigation was carried out using morphological and numerical studies. Fresh materials of Abutilon species were collected from different localities in Saudi Arabia during 2018 and 2019. Numerical analysis was based on the Principle Coordinates, the Principle Component and the Unweighted Pair Group Method with Arithmetic Algorithm Clustering. The results indicated that there were significant differences based on the morphological characters especially in the leaves, fruits and flowers features. Morphometric studies revealed that the six species of Abutilon clearly separated in all different analysis.
