Their karyotypes were analyzed both at interspecific and intraspecific levels. The somatic chromosome number of <em>Alpinia</em> spp. and <em>Amomum</em> spp. was found to be 2n = 4X = 48. The <em>Curcuma</em> spp. represented by <em>C. amada</em> had 2n = 42 chromosomes and three other species <em>viz</em>., <em>C</em>. <em>caesia</em>, <em>C</em>. <em>longa</em> and <em>C</em>. <em>picta</em> had 2n = 63 chromosomes having X=21, indicating that polyploidy is a common feature in this genus. The somatic chromosome number of <em>Hedychium</em> spp. was found to be 2n = 34 chromosomes having a basic no. X = 17. Chromosomal data based clustering pattern and their sub-grouping at intra-specific level validates the taxonomic status of these species. Gower’s similarity matrix is an indicator of cryptic changes leading genus specific karyotype conservatism.</p>}, number={1}, journal={Caryologia}, author={Saha, Kishan and Sinha, Rabindra Kumar and Sinha, Sangram}, year={2020}, month={Mar.} }
