| Description | The taxonomic status of Central European taxa F. pallens s.l., F. psammophila, F. polesica, and F. vaginata was revised using the multivariate morphological analysis of well karyologically documented plants, and AFLP analysis. Six species were recognised: F. pallens Host (relict rocky habitats; diploid); F. csikhegyensis Simonk. (base-rich rocks; tetraploid); F. psammophila (Čelak.) Fritsch (acidic sands) with two subspecies, F. p. subsp. psammophila (sands; E Germany, Poland, Bohemia) and F. p. subsp. dominii (Krajina) P. Šmarda (sands; SW Moravia, C and E Poland); F. vaginata Willd. (base-rich sands mainly in the Pannonian Lowland); F. polesica Zapał. (seaside and inland sand dunes); and F. pseudovaginata Penksza (base-rich sands in the Pannonian Lowland). Identification key and distribution maps as well as informations about type specimens, exsiccata collections, synonyms, and hybrids are provided. Evolutionary relationships with the assumed putative ancestor F. pallens and the rather isolated position of F. polesica are discussed. |
