Updates to the Flora of Voronezh Region

Abstract

The main goal of a research is to confirm and justify findings of some rare plant species in Voronezh region. This is due to the fact that some regional scientists cast some doubt on their status and consider these species as “doubtful”. The doubts concern the following species: 1 – erroneous find in 1988 Lepidium meyeri in the tract “Golick”, Kamenski district of Voronezh region; 2 – downsizing of Tulipa biebersteiniana; 3 – systematic position of Tulipa scythica; 4 – presence of Genista tanaitica in the flora of Krasnyanskaya steppe; 5 – population size of Bulbocodium versicolor etc [1, 2]. Presence of “doubtful” rare plants in the flora of Voronezh region confirmed and justified with herbarium samples from MW, LE, VORG, field studies. Materials and methods. Materials about rare plant species of Voronezh region obtained by following methods: reconnaissance of tracts, collection, processing and identification of herbarium material, compiling an electronic database, photographic work, continuous 34-year old long monitoring. Results. Authentic materials confirm the presence of rare plants. They show evidence for the academic community that mentioned above species can't consider as “doubtful”.
