    Notes: Abstract Giemsa C-banding allows the differentiation of six, otherwise very similar karyotypes from the small genusAnacyclus. “Banding style”—with stable centromeric and nucleolar bands, and diverse specific banding patterns in distal chromosome segments—contributes significantly to generic demarcation and systematic grouping. The amount of banding corresponds to heterochromatic chromocentres and increases from perennials to annuals. Relationships with other nucleotype parameters and evolutionary mechanisms are discussed.

    Giemsa C-banded karyotypes of some diploidArtemisia species (1986)
    Springer
    Plant systematics and evolution 152 (1986), S. 195-210

    Notes: Abstract Detailed C-banded karyotypes of eight diploidArtemisia species from three different sections are reported together with preliminary observations on three additional related diploid species. In the majority, the overall amount of banding is relatively low. Bands are mostly confined to distal chromosome regions; intercalary banding is virtually absent and centromeric heterochromatin is also scarce. With the exception ofA. judaica there is in general great uniformity in karyotype structure but considerable interspecific variation in total karyotype length (and hence DNA content) ranging from 44 µm inA. capillaris (2n = 18) to 99 µm inA. atrata (2n = 18).A. judaica (2n = 16; total karyotype length 97 µm) was distinguished by its karyomorphology, with one large non-banded metacentric chromosome pair and 7 pairs of smaller terminally banded meta- or submetacentric chromosomes.
