Chromosome numbers of some native Iranian plants

Chromosome numbers of 11 native species from five families (Apiaceae, Asteraceae, Brassicaceae, Lamiaceae, and Fabaceae) of Iran were investigated. Most of them are endemic or subendemic species. This study aimed to determine chromosome number and provide general information on karyotype characteristics of selected native species of Iran. For Achillea kellalensis (2n = 18), Noccidium hastulatum (2n = 14), Phlomoides glabra (2n = 22), Astragalus gompholobium (2n = 16), Astragalus urbanus (2n = 16), Astragalus askius (2n = 16), Oxytropis iranica (2n = 16), chromosome numbers are reported for the first time, for Prangos uloptera (2n = 44) for the first time based on material from Iran.
