| Abstract: | In present paper, The karyotypes of nine species and two varieties of the genus Camellia were reported. The results were as following: Camellia henryana: 2n=2x=30=21m 8sm 1st; C. furfuracea: 2n=2x=30=20m 10sm; C. wardii: 2n=2x=30=18m 11sm 1st; C. anlungensis: 2n=2x=30=19m 9sm 2st; C. anlungensis var. acutiperulata: 2n=2x=30=19m 9sm 2st; C. pyxidiacea: 2n=2x=30=20m 8sm 2st; C. pysidiaea var. rubituberculata: 2n=2x=30=21m 8sm 1st; C. brevistyla: 2n=2x=30=18m 10sm 2st; C. leptophylla: 2n=2x=30=24m(1sat) 4sm(1sat) 2st; C. yunnanensis: 2n=2x=30=18m 10sm 2st; C. pitardii: 2n=2x=30=18m 12sm. Nine of them were reported for the first time. Karyotypes were very similar each other among the above species, and comprision between sections was more important than that between species. |
