Abstract : Cytological investigations on some plants in the flora of Madinah region revealed the 'following chromosome counts in the following eight species. Asphodelus fistulosus 2n = 28, Astragalus eremophilus 2n = 16, Erodium oxyrrhynchum 2n = 18, Iris postii 2n = 14, Plantago arabica 2n = 12, Plantago cylindrica2n = 10, Rumex vesicarius 2n = 18, and Schouwia thebaica 2n = 24. The first three spcies and the last one, i.e. S. thebaica have short chromosomes mean length less than 2j1.m.I. postii, P. arabica and R. vesicarius have a mean chromosome length of more than 4 jl.m. The karyotype of I. postii is highly assymmetric with evident variation in length among the chromosome. However, the karyotypes of the other taxa are symmetric. No polyploidy is reported in the examined species. The karyotypes of the examined species are described for the first time in plants from Saudi Arabian flora.
