Abstract :
Apocynaceae have traditionally been divided into into two subfamilies, the Plumerioideae and the Apocynoideae. Recently, based on molecular data, classification of Apocynaceae has undergone considerable revisions. According to the Angiosperm Phylogeny Group III (APGIII, 2009), and the update of the Angiosperm Phylogeny Group APG (APGIV, 2016) the family Asclepiadaceae is now included in the Apocynaceae. The family, as currently recognized, includes some 1500 species divided in about 424 genera and five subfamilies: Apocynoideae, Rauvolfioideae, Asclepiadoideae, Periplocoideae, and Secamonoideae. In this research selected species from the previous families Asclepiadaceae and Apocynaceae were morphologically investigated in an attempt to distinguish morphological important characters supporting their new molecular classification. 40 morphological characters were treated as variables and analyzed for cluster of average linkage between groups using the statistical package SPSS 16.0. Resulting dendrograms confirm the relationships between species from the previous families on the basis of their flowers, fruits, and seeds morphology. Close relationships were reported between species from the same subfamilies.
