Floristic diversity of steppe territories near Poltava town (Ukraine)

Keywords: vascular plants; taxonomy; floristic findings; steppes; Poltava region.


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 type of vegetation in the Forest-Steppe zone of Ukraine is very important for preservation of current steppe territories, the authors studied several territories with steppe vegetation near Poltava town (Poltava region, Ukraine). The key steppe territories found are situated near Abazivka, Rozhayivka, Kostochky, Buhayivka, Machukhy, Ivonchentsi and Zhuky villages. Data about steppe flora from only the first territory located between Abazivka and Rozhayivka villages including “Rozhayivskyi” local botanical reserve were early reported in literature sources while data about steppe vegetation of the other areas has never been published in detail. The full list of 401 vascular plant species found on these steppe territories with the frequency of distribution, major synonym names and references to current taxonomic papers for separate species are proposed. One of these species (Hemerocallis fulva (L.) L.) is a new alien for Poltava region. Taxonomy for all species was critically revised, nomenclature of several taxa (Dichoropetalum carvifolia (Vill.) Pimenov & Kljuykov, Erophila verna (L.) DC., Campanula canescens (Waldst. & Kit.) Roth) is discussed in detail. The name “Dichoropetalum carvifolium-chabraei (Crantz) Soldano et al.” is an invalid designation based on trinominal and must be rejected. The names Selinum chabraei Jacq. ex Murray, Peucedanum euphimiae Kotov and Hemerocallis lilio-asphodelus var. fulva L. were lectotypified. The studied steppe territories have the great significance in the sozological aspect, they include 32 rare steppe plant species (seven from the Red Data Book of Ukraine and 25 from the list of locally rare plants within Poltava region) so the primary task for further research is to organize their protection as the most valuable steppe areas and the monitoring of their condition in the future.
