| Abstract: | This paper deals with chromosomal number and morphology of 7 species of Clematis L. in China. The results are summarized in Table 1. According to the basic number of the genus (x=8), these species can be refered to diploid and tetraploid.The following Clematis forms are studied cytologically, the chromosome number and the karyotype formula are as follows:The chromosomal numberSpecies &the karyotype formulaC.aethusifolia Turcz. 2n(2x)=16=10m+6st(2SAT)C.aethusifolia var. 2n(2x)=16=10m+6st(2SAT)latisecta Maxim.C. intricata Bunge 2n(2x)=16=10m+4st+2t(2SAT)C.hsxapetala Pall. 2n(2x)=16=10m+4st+2t(2SAT)C.finestiana Levl.et Vant. 2n(2x)=16=10m+4st+2t(2SAT)C.terniflora DC. 2n(4x)=32=20m+8st(2SAT)+4t(2SAT)C.huchouensis Tamura 2n(4x)=32=20m+6st(4SAT)+6t(4SAT)In addition, some species are taxonomically discussed. |
