Morphological and micromorphological study of some species of Apocynaceae family using in Iran

Apocynaceae AL De Jussieu family (Gentianales) consists of tree plants, shrubs or grasses that have leachates in the tissues. This family is one of the largest families of Angiosperms in the world that include 375 genera and over 5100 species worldwide. The family is highly regarded in the medical field for its widespread use in chemotherapy for cancer, skin diseases, diabetes, diarrhea, and malaria. In this research, the morphology of vegetative and reproductive organs of 7 species of this genus in order to evaluate their final value in the definition of species Variation between them was studied. Based on Flora Iranica, 44 quantitative and qualitative traits of morphology and 11 quantitative and qualitative characteristics of micromorphology were selected. In the end, for analyzing the data obtained from the study, quantitative traits and Qualitative and cross-species analysis of the taxonomic variation was performed using computer software NTSYS (version 2.02e) with Dice similarity coefficient and UPGMA clustering. The results of this study showed that the similarity thresholds were 58% and dendrograms of traits Micro-morphology shows the similarity threshold of 50% between species. The results of this study indicate that morphological and morphological traits are very useful for the detection of different species of lucerne family in Iran
