Chromosome numbers (somatic and gametic) of 21 species of eight families of angiosperms, collected in the wild in Kuwait, are reported. Most of them are the first counts in Kuwaiti populations. Included are the first report for Anisosciadium lanatum (2n = 18) and new numbers for Aizoon hispanicum (2n = 18), Astragalus annularis (2n = 24) and Pallenis hierochuntica (2n = 12). The karyotypes of Astragalus annularis and A. spinosus are illustrated.
