| Popis | Chromosome numbers for 98 plants of F. pallens (2n=14+0-1B,21+0-1B,28+0-1B), 19 of F. psammophila (2n=14), F. belensis (2n=14) and F. vaginata (2n=14), and 44 of F. ovina (2n=14, 2n=28+0-5B) originating from Austria, the Czech Republic, Germany, Slovakia and Latvia are given. In addition to the F. ovina and F. pallens groups, chromosome counts for the following taxa are also reported: F. alpestris 2n=14, F. amethystina subsp. amethystina 2n=28, F. brevipila 2n=42, F. cinerea 2n=28, F. rupicola subsp. rupicola 2n=42 and F. versicolor subsp. versicolor 2n=14. One new tetraploid type (F. pallens "scabrifolia") from the Czech Republic and Germany is reported and its taxonomy is discussed. Chromosome numbers for F. psammophila subsp. muellerstollii and F. belensis (both 2n=14) were determined here for the first time. A complete survey of published chromosome counts for Central European species from the F. ovina and F. pallens groups is included. |
