Article
Full-text available
Current progress in botany requires new claims for floristic research. Now the latter is not a simple species inventory of a separate local or regional flora but it needs coordination with recent results of critical taxonomic, nomenclatural and molecular phylogenetic investigations. Based on the fact that detailed research on steppes as a zonal typ...
Article

During field expeditions in 2005–2018 in Poltava region author found 12 vascular plant species which are very rare on this territory and need conservation. He proposes to include them in the List of regionally rare plant species within Poltava region. These plant species are: Carex brevicollis DC. (relict nemoral Submediterranean species with isolat...

The protected area of Dzharylhatskyi National Park is only 3% of the total area. This is not enough to preserve dynamic ecosystems that are very vulnerable to natural factors and almost impossible to restore following damage by anthropogenic factors. In the investigated area there are territories with high potential for conservation, which are char...

Classification and nomenclature are important elements of vegetation sudies based on ecological-floristic (Braun-Blanquet’s) approach. Ukrainian geobotanical publication analysis showed that a lot of mistakes had been made by many Ukrainians authors in the publishing of new syntaxa so these names become invalid. Author distinguishes 10 incorrect pu...

It is demonstrated that the name Cynanchum rossicum was invalidly published by Kleopow (1929) as a provisional name. In the same article he validly published C. meoticum as “Cynanchum (Vincetoxicum) meoticum”, probably with an intention to create a corresponding alternative name in Vincetoxicum. However, our analysis of the protologue demonstrates...
