Houttuynia cordata Thunb. (Saururaceae), has the chromosome number of 2n = 112 with karyotype formula A2+B98+C12. The size of the chromosomal complement was found to range from 1.52 µm to 3.00 µm with one pair of chromosomes bearing secondary constrictions. The detailed karyotype analysis revealed that chromosomes fall under the Stebbins category of 1A, which indicating slightly asymmetric nature of chromosome. The chromosome tally and conformity of the karyotype in the present study corroborated as a new cytotype being adapted in this area, the north-eastern region of India.
