Abstract
The first comprehensive karyological overview of the group of Festuca circummediterranea, comprising 10 Euro-Mediter- ranean taxa (5 species and 7 subspecies, including autonyms), is provided. Thirty populations were sampled from across almost the whole distributional range of the aggregate, including the loci classici of each taxon. The first chromosome counts for F. jeanpertii subsp. jeanpertii, subsp. achaica, and subsp. gracilis are reported. All the taxa were found to be diploid (2n = 14) and have a similar karyotype, characterized by the predominace of metacentric and submetacentric chromosomes; the occurrence of B-chromosomes was recorded from a single taxon, F. marginata subsp. gallica.File | Dimensione | Formato | |
