Background and Aims: Tigridia pavonia was proposed as an allotetraploid taxon 2n=4x=28, but without cytogenetic evidence supporting its hybrid origin. It is a widespread species in Mexico and its populations lack karyotype and detailed analysis of chromosomes with satellites as a criterion to determine the number of nucleolar organizers that confirm or not nucleolar dominance. In this paper, we analyze and describe the number and chromosome architecture of T. pavonia from a Mexican population in search of evidences that support or discard its hybrid origin and we propose a karyotype according to the level and origin of ploidy. Methods: A surface spreading and air drying technique was used that includes enzymatic maceration and hypotonic s...
