Afroalpine plants of the afroalpine environment, the scattered high mountains of Ethiopia and TropicalrnEast Africa, have not been widely studied. Ten species of afroalpine plants were sampled randomlyrnfrom Bale Mountains and their mitotic chromosomes have been studied or determined using an air-dryrnmethod. For chromosome preparation, root tips were pretreated with ice-cold water (24hr) orrncolchicine (3â€“4hr), fixed in 3:1 (ethanol:glacial acetic acid) and air-dry slide preparation was madernfollowing cellulose-pectinase maceration (37oC,1hr) and stained in Giemsa. For the karyotypicrnanalysis, photographs were taken from the best metaphase plates of each specimen. Ideogram wasrntaken and chromosomes types were determined according to Levan et al., criterion. The result showedrnthat, the chromosome numbers of 2n = 20 for Centella asiatica L.; 2n = 72 for Cotula cryptocephala;rn2n = 40 for Senecio nanus; 2n = 56 for Crassula alsinoides; 2n = 28 for Geranium arabicum; 2n = 28rnfor Lobelia rhychopetalum; 2n = 12 for Plantago major; 2n = 18 for Rumex nepalensis; 2n = 32 forrnRanunculus oreophytus and 2n = 32 for Ranunculus multifidus. Karyotypes have been constructed forrnSenecio nanus, Plantago major and Ranunculus oreophytus species. The first two species havernsymmetrical karyotype consisting metacentric chromosomes, whereas the latter species showedrnasymmetrical karyotype with metacentric, sub-metacentric and sub-telocentric chromosomes. Thernchromosomes length of Senecio nanus, Plantago major and Ranunculus oreophytus range betweenrn2.28 and 11.35Î¼m. Since detailed karyotypic analysis could not be given to the most species under thernpresent study, it is better to carry out further cytological study in the future to get more reliablernchromosome data for better understanding about their taxonomic and evolutionary relationships.Key words: Afroalpine environment, Afroalpine plants, Bale Mountains, Chromosome numbers,rnChromosomes length, Karyotype, Ideogram.
