The paper deals with the richness and diversity of endemic and subendemic taxa in the Polish Carpathians. Based on critical studies in the literature and the authors' unpublished materials collected in the field, the distribution patterns of endemic species are analysed and discussed. The participation of endemics in the flora of single Carpathian ranges is assessed and analysed. The importance of the Tatra Mts as a centre of endemism is stressed. The frequency and altitudinal ranges of endemic taxa are characterized and their syntaxonomical spectrum is presented.

The paper reports the results of karyological studies on seven fern species from the Polish Carpathians. Their chromosome numbers counted in root tip mitoses are reported for the first time from Poland. The specimens originated from the Tatra Mts and Pieniny range. Chromosome numbers were established for Asplenium viride (2n = 72), Athyrium filix-femina (2n = 80), Dryopteris filix-mas (2n = 164), Gymnocarpium dryopteris (2n = 160), Gymnocarpium robertianum (2n = 160), Phegopteris connectilis (2n = 90) and Phyllitis scolopendrium subsp. scolopendrium (2n = 72). The chromosome numbers from the Polish material match those reported from other countries. Information on the distribution and habitats of the investigated fern species is also provided.
