Hedera pastuchovii has a chromosome number of 2n= 144 (6x), making it a hexaploid. In a recent study of phylogenetics, H. pastuchovii, has been found to be related to other species of parsimony through a test of cpDNA restriction site variation analysis. In the clade containing Asian taxa, the results showed that the pre-existing phylogenies are largely congruent to one another, helping to place one additional clade helped resolve the positions of H. maroccana, H. iberica, and H. canariensis in the combined analysis.
