Rubus bohemo-polonicus Travnicek & Zieliński, a regional species belonging to series Radula (Focke) Focke, is described from the Czech Republic and Poland. It differs from closely related species (R. radula Weihe, R. salisburgensis Focke ex Caflisch and R. indusiatus Focke) mainly by the almost glabrous stems and consistently white petals. Illustrations and a distribution map of the new species are provided.

Rubus clusii Borbás is a species which occurs in Central Europe, from southern Germany, Czech Republic, southwestern Slovakia, through western Hungary andAustria to Slovenia. Nine new localities of this taxon were found in southeastern Poland, which considerably extends its geographical range. The results of one study suggest that the present definition of the species range was based on incomplete data, missing its potential localities. Therefore, we expect further extension with more localities identified.

This paper presents the results of extensive field research on the occurrence of Rubus L. species in the Czech Republic, especially in the frontier areas near the German border. In this area, Rubus adornatus, R. fasciculatiformis and R. perlongus were newly discovered. The other species, R. ambulans and R. stohrii, were discovered in the eastern and northern parts of Bohemia. A description, an illustration, photos and a list of localities are provided for each species. Taxonomy and nomenclature, ecology, distribution and etymology are discussed. The ploidy level of the mentioned species is presented here for the first time. All of these species are new for the flora of the Czech Republic.

A study of the very complex, from the taxonomic point of view, Taraxacum genus was undertaken in the area between the towns of Cieszyn and Bielsko-Biała (S Poland). Taraxacum species belonging to three sections: sect. Hamata H. Øllg. (three species), sect. Palustria (H. Lindb.) Dahlst. (one unidentified taxon), and sect. Ruderalia Kirschner, H. Øllg. et Štěpánek (61 species) were recorded. Nine species new to Poland were found: T. acutifrons Markl., T. ancistratum H. Øllg., T. bellum H. Øllg., T. chrysophaenum Railons., T. deltoidifrons H. Øllg., T. horridifrons Railons., T. pronilobum H. Øllg., T. rhamphodes Hagl., T. violaceifrons Trávníček. Presence of three other species, whose localities hitherto have not been exactly given, was confirmed: T. aberrans Hagendijk, van Soest et Zevenbergen, T. fasciatum Dahlst. and T. gibberum Markl. (all they belong to the section Ruderalia). For most species, the details of their occurrence in Poland were also reported. The species new in Poland are briefly described and illustrated with photographs of herbarium specimens.
