N2  - Somatic chromosomes at mitotic metaphase of Bowenia serrulata, B. spectabilis and B. sp. &#8216;Tinaroo&#8217; is investigated by the standard aceto-orcein staining method and the fluorescent in situ hybridisation method (FISH) with ribosomal DNA (rDNA) probe. Bowenia serrulata, B. spectabilis and B. sp. &#8216;Tinaroo&#8217; each have a chromosome number of 2n = 18. The karyotype of B. serrulata exhibits 10 median-centromeric chromosomes, while B. spectabilis and B. sp. &#8216;Tinaroo&#8217; exhibit eight median-centromeric chromosomes. By using FISH, B. serrulata, B. spectabilis and B. sp. &#8216;Tinaroo&#8217; show a hybridisation signal on the satellite of the short arm of two submedian-centromeric chromosomes. However, the other hybridisation signal pattern is different among B. serrulata, B. spectabilis and B. sp. &#8216;Tinaroo&#8217;.
