Description

1) The report deals with the results of karyotype analysis on two species of Iris, viz. I. gracilipes and I. japonica.
2) I. gracilipes (2n = 36) is diploid. Morphologically, two set of the chromosomes are similar to each other.
3) I. japonica (2n = 54) is triploid. Three set of the chromsomes are not similar in shapes and length. Juding from the karyotype, the species is to be considered partial allotriploid.
4) As the karyotype of the two species is quite different in each other, a direct relation is doubtful between them.
