Costus spicatus (Jacq.) Sw. is a species of Costaceae (Zingiberaceae) family, which is most familiar as a medicinal plant because of its therapeutic values. A detailed karyological analysis has been accomplished through aceto-orcein staining, chromosome number was reported 2n=18 along with the presence of one B-chromosome, which exhibited with a karyotype formula as 16m+2sm. It would be a new report for C. spicatus. The esteems of various karyomorphological indices regarding the aspect of asymmetry, demonstrated its symmetry in the karyotype. Therefore, the basic chromosomal information of the current investigation will contribute to deposit chromosomal knowledge and conservation of plant genetic resources of C. spicatus as an invaluable medicinal plant.
