Contribution to the flora of Asian and European countries: new national and regional vascular plant records, 2

Abstract The paper presents new records for 20 vascular plant species from eight Asian and two European countries. Five taxa (Artemisia campestris, Artemisia tanacetifolia, Delphinium sajanense, Diarthron vasiculosum var. undulatum, Epilobium adenocaulon) are reported from Kazakhstan, four (Deyeuxia yanyuanensis, Poa arnoldii, Stipa gracilis, Stipa macroglossa subsp. kazachstanica) from China, three (Nepeta pamirensis, Silene bucharica, Scrophularia pamiro-alaica) from Uzbekistan, two (Epilobium nervosum, Stellaria zolotukhinii) from Mongolia, two (Oenothera deflexa, Scirpus georgianus) from Poland, one (Coronopus didymus) from Tajikistan, one (Orobanche rumseiana) from Italy, one (Stipa macroglossa subsp. kazachstanica) from Kyrgyzstan, one (Poa polozhiae) from Russia, and one (Agrostis rupestris) from Azerbaijan. All of these taxa are new to the floras of listed Asian and European countries or its regions (as it is in the case of China or Russia). Four of the presented taxa (Coronopus didymus, Epilobium adenocaulon, Oenothera deflexa and Scirpus georgianus) are regarded as alien to the studied areas, whereas the other 16 are new native elements to the flora of the countries. For each species synonyms, general distribution, habitat preferences, taxonomy with remarks on recognition and differentiation of the species from the most similar occurring in a given country, as well as a list of localities recorded (often far from the previously known areas) are presented. In the case of Orobanche rumseiana, a new variety O. rumseiana var. sarda R. Piwowarczyk and A. Pujadas is described and illustrated.
