Ling previously placed in Pyrethrum collected in (1) Russian Federation, Altai Republic, Altai Terr,, Kosh-Agacz District, Vicinity of Elongash River, 49°50’03”N, 088°02’96”E, alt. 2,450 m elevation; (2) Russian Federation, Altai Repiblic, Kosh-Agacz District, Mt. Talduair, 50°09’35”N, 089°23’53”E, alt. 2,300 m showed commonly the resting nucleus of the complex chromocenter type, the prophase chromosomes of the interstitial type, the chromosome number of 2n=18, and the typical diploid karyotype with 14 median- or submedian-centromeric chromosomes (of which two had satellites) and four subterminal-centromeric chromosomes (of which 1-3 had satellites). Those chromosome characters were same as those of the diploid species previously described.
