“…Its chromosome morphology is also constant within and between populations with a karyotype of 2n = 10m + 4sm + 2t (Fig. E− H), and essentially identical with that of all the other species with available karyotypic data in Cimicifuga (Kurita , Ramsey , Hasegawa , Emura (Hasegawa) , , , Yang et al , Wang et al , Lee and Park , Yang , Yuan and Yang ). In fact, the only two tetraploid species known in the whole genus Cimicifuga (including Actaea and Souliea ) are the Sino‐Himalayan C. frigida Royle (Ren et al ) and the Kashmir Himalayan C. kashmiriana J. Compton & Hedd.…”

Cimicifuga nanchuanensis P. K. Hsiao (Ranunculaceae) has been regarded as an imperfectly known species. Based on critical examination of herbarium specimens and living plants we have determined that it is a morphologically distinctive species and that its geographical range is much wider than believed before, far from locally endemic to its type locality. Our cytological examination reveals the species to be a diploid (2n = 16). Our molecular phylogenetic analyses using nrDNA and cpDNA datasets confirm our morphological observations. As the generic concept and delimitation of Actaea L., in which Cimicifuga Wernisch. and Souliea Franch. are included, have also been strongly corroborated by our molecular phylogenetic analyses, here we adopt a broad Actaea and make a new combination for the species in question, i.e. Actaea nanchuanensis (P. K. Hsiao) J. P. Luo, Q. Yuan & Q. E. Yang.

“…Our observation of female individuals agrees with the previous chromosome number count (Lee and Park 1998). C. simplex also has broad distribution areas in Asia including China, Russia, Korea, and Japan (Lee and Park 1998;Park 2007).…”

“…C. simplex also has broad distribution areas in Asia including China, Russia, Korea, and Japan (Lee and Park 1998;Park 2007). From Japanese and Korean populations, two types of morphological groups were recognized corresponding to two cytological types, demonstrating potential varieties (Lee and Park 1998). Further investigation on morphology and cytology for C. simplex with more population sampling covering broad geographic distribution areas is needed to verify potential taxonomic varieties.…”

Chromosome numbers of 28 taxa in 10 genera of the Ranunculaceae (buttercup family) from the Korean peninsula

Somatic chromosome numbers of 28 Korean native species in the buttercup family are observed and analyzed. The plants include 10 genera with seven endemic taxa to the Korean peninsula, and most of them are the first reports from Korean populations. In particular, the chromosome numbers for the two taxa are reported for the first time: Clematis fusca var. coreana (H. Lév) Nakai (2n = 16) and Thalictrum aquilegiifolium var. sibiricum Regel & Tiling (2n = 42). The Ranunculus type chromosomes (R-type, c.3-12 μm long) are found in Megaleranthis, Actaea, Cimicifuga, Anemone, Clematis, Hepatica, and Ranunculus, whereas Aquilegia and Ranunculus have the Thalictrum type chromosomes (T-type, c.1-1.5 μm long). The two types of chromosomes in Ranunculus, one of the species-rich genera in the family (c.600 species worldwide), suggest that chromosomal differentiation plays an important role in species diversification in the genus. Evaluation of cytogenetic features in a phylogenetic frame is suggested for a better understanding of the evolutionary history of the family.

“…The chromosomes were fairly large, belonging to R‐type. In the karyotype reported by Emura (1970a), and that by Lee & Park (1998), a pair of small satellites was observed on the short arms of the fourth chromosome pair in both Korean and Japanese populations, and one small satellite on the short arm of one of the eighth chromosome pair in the Korean population or a pair of small satellites was observed on the short arms of the eighth chromosome pair in the Japanese population.…”

The karyotypes of 16 species and one variety representing nine genera in the Ranunculaceae were analysed in order to obtain information on the placement of the genera Beesia and Eranthis at tribal rank in the family. Those of Beesia , Anemonopsis , Souliea , Cimicifuga , Actaea and Eranthis were found to be very similar to each other, but remarkably different from those of Caltha , Calathodes , Megaleranthis and Trollius with respect to chromosome size and morphology. From cytological data it is clearly evident that Beesia and Eranthis have a much closer affinity to Anemonopsis , Souliea , Cimicifuga and Actaea in the tribe Cimicifugeae than to Caltha , Calathodes , Megaleranthis and Trollius , which generally have been placed together in a single tribe, albeit with different tribal names such as Caltheae, Trollieae and Helleboreae. Therefore, Beesia and Eranthis may find better placement in the tribe Cimicifugeae. The long-presumed, mainly morphology-based close affinity between Eranthis and Helleborus is not supported by both cytological and palynological data. Cytologically, both Actaea and Eranthis appear to be the specialized genera in the Cimicifugeae, through having the most asymmetrical karyotypes in this tribe. Our results strongly support the recent re-definition of the tribe Actaeeae (as Cimicifugeae) to include Beesia and Eranthis , based on maximum parsimony analysis performed separately on molecular data.
