New national and regional plant records: Contribution to the flora of the Old World countries

This paper presents new data on the occurrence of 16 vascular plant species from five Eurasian countries obtained during field explorations, as well taxonomic revisions herbarium materials. Five taxa (<i>Draba fladnizensis</i>, <i>Gentiana orbicularis</i>, <i>Helianthus giganteus</i>, <i>Symphyotrichum cordifolium</i>, <i>Thalictrum alpinum</i>) are recorded for first time Poland, (<i>Achnatherum jacquemontii</i>, <i>Arrhenatherum elatius</i>, <i>Dittrichia graveolens</i>, <i>Geranium pyrenaicum</i>, <i>Stipa</i> × <i>balkanabatica</i>) Tajikistan, three sibiricum</i>, <i>Asyneuma thomsonii</i>, Kyrgyzstan, one (<i>Orobanche bartlingii</i>) Turkey, (C<i>alamagrostis obtusata</i>) China and (<i>Calamagrostis emodensis</i>) Gansu Province in China. In addition, <i>Hieracium piliferum</i>, considered extinct was rediscovered. For each species, synonyms, taxonomy with remarks recognition differentiation most similar occurring a given area, general distribution, habitat preferences, list localities (often far previously known areas) presented. As result morphological comparison specimens representing <i>balkanabatica</i> collected Tajikistan Kyrgyzstan type specimen Turkmenistan, we decided to describe variety named <i>S</i>. var. <i>alaiensis</i> M. Nobis & Klichowska, <i>var. nov</i>. Additionally, based analysis phytosociological relevés prepared studies western Pamir Alai Mts (in Tajikistan), association chasmophytic plants <i>Asperulo oppositifoliae</i>–<i>Achnatheretum jacquemontii</i> Nobis, Klichowska A. Nowak, is also described.
