Abstract : Tubers of the species and varieties of Chlorophytum under consideration were collected from different places of Ranchi and cytotaxonomical studies were carried out. All the species and varieties were found to be tetraploid with 2n = 28. The karyotypes of all the species showed ‘nearly submedian’ and ‘submedian’ chromosomes in high proportion while ‘subterminal’ chromosomes were very few in number. Chromosomes with secondary constrictions were common in both the varieties of C. borivilianum and C. tuberosum whereas, it was completely absent in the other two species and varieties under consideration.
