Abstract
Morphological and phylogenetic (nrITS barcode) analyses are conducted to clarify the taxonomic status of 10 Delphinium species (D. cuneatum, D. dictyocarpum, D. duhmbergii, D. elatum, D. litwinowii, D. pubiflorum, D. puniceum, D. sergii, D. subcuneatum, D. uralense) occurring in the South-East of European Russia. The morphometric analysis is carried out with 22 quantitative and 32 qualitative parameters. Based on all parameters, the nMDS supports the differentiation of D. puniceum, D. sergii, D. uralense and D. pubiflorum whereas other studied taxa remain undistinguished. Furthermore, the Random forest analysis and the MrBayes phylogenetic analysis of ITS sequences confirm the species status of D. puniceum belonging to D. sect. Diedropetala and D. elatum, D. uralense, D. dictyocarpum and D. pubiflorum belonging to D. sect. Delphinastrum. Finally, recursive partitioning is performed to develop the dichotomous key which can be used to identify the species of Delphinium in the study area. In conclusion, we stress that the recognition of species belonging to D. sect. Delphinastrum is hindered by the presence of numerous intermediate or hybrid forms, on the one hand, and the impact of climatic conditions on the morphological (and, specifically, taxonomically significant) traits, on the other hand.
