The paper presents a discussion of the information about xerothermical species obtained by modern molecular techniques, compared to the knowledge based on classic research. Molecular data can be an important new element in the study of the origin and the time of migration of xerothermic species to southern Poland and more broadly, to Central Europe. The results of the molecular study indicate that among the species of plants there are those that have been occurring and differentiating in Central and Eastern Europe for a time longer than that since the last glacial period, as reported previously in the literature. The analysis indicated also that the main migration route of the xerothermic species ran westward along the northern side of the Carpathian Mts but did not support the existence of a direct route from the south via the Moravian Gate. The divergence of genetic lineages identified in the study in southern Poland suggests that the populations from the Wyżyna Małopolska upland had an independent history and are older than those from the Wyżyna Lubelska upland.

In this paper phytosociological characteristics of some vascular plant invasive species are given. Probability of common invasive species co-occurrence was described as well. Research was carried out during 2010-2014 in the valleys of the Carpathian tributaries of the Vistula River, and along the Vistula River in Sandomierz Basin.

Genetic diversity and population genetic structure of Carlina onopordifolia Szafer ex Besser, one of the rarest species of the Polish flora, were studied using AFLPs. All natural and introduced populations (altogether 13) occurring in Poland were analyzed. The obtained results show that all populations are characterized by a very even (and generally low) level of genetic diversity. There was no evidence of any genetic difference between natural and introduced populations. On the other hand, significant genetic differentiation between populations group from the Wyżyna Małopolska upland and populations group from (together) the Wyżyna Lubelska upland, the Polesie Wołyńskie lowland and the Wyżyna Zachodniowołyń ska upland was revealed.

Invasive species are, since many years, of great interest of ecologists due to the threat they cause to biodiversity, particularly when national parks and nature reserves are taken into account. In the paper several new localities for 11 invasive species are provided. Six of them (Bromus carinatus, Conyza canadensis, Erigeron annuus, Heracleum sosnowskyi, Impatiens glandulifera, Solidago gigantea) are new for the Tatra National Park.

sium eriophorum (L.) scop, is a rare and endangered species both in the Tatra Mts and in other Polish part of the Carpathians. The species was not known till now from the eastern part of the Tatra National Park. In the paper three new localities from this part are recorded.

Betonica officinalis is the lowland species. In the Carpathians it is known only from the foothills (colline zone) and as a very rare from a few localities in the lower montane belt. So far the species was missing from the Tatra Mts. The paper provides information on two localities found in 2012 year from this area.

The list of rare vascular plants in the Vistula River valley in the Kotlina Sandomierska basin (the part between Raba and Wisłoka Rivers mouths) is presented. It contains i.e. species new or rare in this part of Vistula River valley, in the Kotlina Sandomierska basin, or in the whole Vistula River valley, as well as in Poland. 21 species endangered in Poland (e.g. Viola elatior), and similar number of species protected in Poland (e.g. Colchicum autumnale) are given in the list. Carex buekii was noted in the Vistula River valley for the first time.

The article contains list and distribution maps of vascular plant species mainly new or rare in the meadows of the Puszcza Niepołomicka forest and adjacent areas between the Vistula and Raba Rivers, noted in 2008-2014. New localities are given for: 1) species recorded for the first time to the Puszcza Niepołomicka forest and adjacent areas: Anthylhs vulnerana, Cirsium canum. Genista tinctoria. Inula salicina, and Verbascum blattaria', 2) very rare and rare species, and 3) two species more frequent between the Vistula and Raba Rivers. Especially important are new localities of vulnerable and/or protected species in Poland: Album angulosum, Cnidium dubium, Dianthus superbus, Gentiana pneumonanthe, Gladiolus imbricatus. Iris sibirica. Lathyrus palustris, and Primula veris.

It was clarified, based on original literature sources, that the information on occurrence of Seseli hippomarathrum L. in Poland (KOCZWARA 1960) was a mistake. The German village name of "Kransdorf" (in fact Kronsdorf, now Krousov) in Moravia given by REICHARDT (1856), repeated by FIEK'S (1881) and later authors (in works by which another misspelled form, "Krausdorf", appeared), was erroneously identified with Kranzdorf (now Nowy Browiniec near Prudnik, Polish Silesia). Addition of imprecise geographical data in Fiek's (1881) work complicated even further the task of the proper identification of the place and contributed to fixation of its name spelling error in the literature for more than 150 years.

The only one known Polish locality of Rhododendron luteum was reported from "Kolacznia" Nature Reserve neAR Wola ZARczycka in Sandomierz Basin. It has been discovered in 1909. The observations of different botanists have also proved that yellow azalea does not breed generatively. The new locality of Rhododendron luteum has been found a few hundred meters from the reserve border. It covers about 2 m2 with a few dozen shoots of yellow azalea. It is probably one, highly branched specimen which is about twenty yeARs old. The new locality is probably natural and was formed from spreading seeds from the ARea of reserve. Few seedlings have also been found on the old locality in 2011. Discovering the new locality proves the possibility of existence of more localities of this species in the vicinity of "Kolacznia" reserve.
