Abstract

ABSTRACTThe paper presents new records of 24 vascular plant species from 11 Eurasian countries. One taxon (Orobanche laxissima) is reported from Armenia; one (Epipactis condensata) from Azerbaijan; two (Phragmites americanus, Polygala multicaulis) from Belarus; one (Stipa caucasica) from Egypt; one (Puccinellia hauptiana) from Kyrgyzstan; three (Aquilegia xinjiangensis, Geranium saxatile, Ranunculus songaricus) from Mongolia; one (Stipa roborowskyi) from Pakistan; three (Echinochloa muricata, Erigeron acris subsp. podolicus, Hypericum majus) from Poland; six from Russia, whereof one (Zanthoxylum armatum) from the European part of Russia and five (Chaerophyllum aureum, Elsholtzia densa, Poa compressa, Ranunculus subrigidus, Viola sororia) from the Asian part of Russia; two (Ludwigia repens, Sagittaria latifolia) from Slovakia; and three (Rubus ambrosius, Rubus camptostachys, Rubus perrobustus) from Ukraine. For each species, synonyms, general distribution, habitat preferences, taxonomy with remarks on recognition and differentiation of the species from the most similar taxa occurring in a given country, as well as a list of recorded localities (often far from the previously known areas), are presented.

Highlights

  • During the field exploration across the vast area of European and Asian countries, as well as during taxonomic revisions of herbarium material of different groups of vascular plants, we found some species which are new to the floras of particular countries or its significant regions

  • The purpose of this paper is to report new records for 39 vascular plant species from eight Eurasian countries

  • Taxonomic notes The concept of Aniselytron Merrill proposed by Korthof and Veldkamp (1984), comprising two species (Aniselytron agrostoides (Kuntze) Soják and Aniselytron treutleri Merrill), is usually used in some floristic treatments and checklists in southeast Asia [Hsu et al, 2000; Kress et al, 2003; Lu and Phillips, 2006]

Summary

Introduction

It might seem that good knowledge on the general distribution of vascular plants has been attained. The present paper is dedicated to new national and regional vascular plant records, to broad our knowledge on their distribution and taxonomy. During the field exploration across the vast area of European and Asian countries, as well as during taxonomic revisions of herbarium material of different groups of vascular plants, we found some species which are new to the floras of particular countries or its significant regions (provinces or republics). The purpose of this paper is to report new records for 39 vascular plant species from eight Eurasian countries. This work aims to contribute to a better understanding of spreading directions of particular vascular plants as well as species composition of selected countries and/or geographical regions of Eurasia
