Abstract

In order to explore the karyotype and evolutionary trend of Clematis and provide taxonomically useful data, the chromosome number, the number and position of satellites, the karyotype formulae, the karyotype, arm ratio, relative length centromeric index, and the index of the karyotype asymmetry of 11 species of the genus Clematis were studied. All the analyzed species showed the same stable chromosome number (2n = 2x = 16) and basic chromosome number 8. Clematis karyotypes are composed by metacentric, submetacentric, and terminal centromeric chromosomes. Clematis lanuginosa, C. otophora, C. lasiandra, C. shenlungchiaensis, C. florida var. plena, C. fusca var. violacea, C. crispa, and C. viticella belong to Type 2A, a very symmetric and plesiomorphic type. Clematis henryi, C. integrifolia, and C. japonaca belong to Type 2B, which is apomorphic relative to the other group. The 11 species of Clematis are different in karyotype parameters providing data for the taxonomy of the genus.
