The chromosome number and karyotype analysis of Paroncyhia amani var. amani andP. amani var. minutiflora are described for the first time. The diploid chromosome numbers andkaryotype formulae are 2n = 4x = 36 = 32m + 4sm in taxa. The karyotypes are symmetrical typeincluding metacentric and submetacentric chromosomes. The small chromosomes varied from 0.96 μm(var. amani) to 2.74 μm (var. minutiflora). P. amani var. amani and P. amani var. minutiflora are verylittle different varieties morphologically. There are some similarities between varieties in thekaryological data. (i) equal number of chromosomes, (ii) same karyotype formula, (iii) very closekaryotype asymmetry values, (iv) polyploidy by ploidy level of 4x. These seem to supportmorphological closeness.
