Analysıs of the genera Inula L. and Pentanema Cass. (Asteraceae) ın the flora of Azerbaıjan

Abstract

The article discusses the changes in the taxonomic structure and the current situation of the genus Inula, which belongs to the tribe Inuleae of the family Asteraceae. Classical comparative-morphological and systematic methods were used during the research. Taxonomic and nomenclature changes in the Inula genus were investigated according to morphological analysis, literature data and databases (“Taxon” and “Ukrainian Botanical Journal”; World Plants: Synonymic Checklists of the Vascular Plants of the World) and it was determined that some species of the genus Inula were transferred to the genus Pentanema which is new to the flora of Azerbaijan. The genus Inula is traditionally a strong polyphyletic in large numbers. It has been suggested to relate them only type species I. helenium L. and species close to it. Other species belonging to the genus Inula are represented in the composition of the genus Pentanema. The genus Inula is supplemented by the species I. aucheriana and is currently represented in the flora of Azerbaijan by 5 species (I. helenium, I. grandiflora, I. montbretiana, I. acaulis, I aucheriana), the genus Pentanema by 9 species (P. orientale, P. germanicum, P. asperum, P. mariae, P. caspicum, P. oculus-christi, P. britannica, P. auriculatum, P. squarrosum). A new key of the species and genera was compiled and a brief overview was given.
