Abstract :

The genus Delphinium belongs to the Delphinieae tribe and Ranunculaceae family; in Iran according to flora Iranica has 29 species with zygomorphic flower. In this study, the morphological information of flower and spur in Delphinium species was studied to determine the importance of these characters in identifying species of this genus. Inflorescence condition, flower color, sepal flower, the color of sepals and petals comparative to each other, spur shape, spur curvature and spur tip were investigated. Statical analysis was conducted by SPSS software and cluster analysis was performed by Average linkage method. The results showed that flower color is one of the important traits in identifying Iranian Delphinium species, so that these genera are divided into two groups of yellow and non-yellow flower. Also, shape and spur curvature can differ from cylindrical, attenuate and inflatum. However, these character don’t correlate with distribution and the area where plant is grown. D. saniculifolium has a inflatum spur among specimens. Herbarium image of flower in different species are presented.
