Phenetic study on Iranian Delphinium and Aconitum species (Ranunculaceae) based on morphological characters

In order to Identification of Ranunculaceae, morphological information of Delphinieae (Delphinium, Aconitum and 2 species of Consolida) was investigated to clarify taxonomic grouping this tribe. Delphinieae contains annual and perennial herb that similar in many anatomical and morphological traits. It was performed Morphological studies on 49 quality and quantity characteristics. Statistical analysis was conducted by SPSS software and cluster analysis was performed by Average linkage method. PCA analysis was performed and the most variable character were identified. The first group includes Aconitum species and the second main group includes Delphinium and Consolida taxa (two species of Consolida were studied). Principle Component Analysis Showed that most variable character include: root form, tepal form, stem striate, stem color, bract form and anther color. Based on the phonogram obtained, the results of numerical taxonomy studies confirm the classical classification available in most flora. The findings of this study confirm that D. elbursense var. gymnobotrys could be have higher taxonomic level.
