Abstract: In present paper,The Karyotypes of nine specis and two varieties of the genus Camellia were re - ported The results were as following:Camellia henryana: 2n = 2x = 21m + 8sm + lst;C.furfuracea:2n = 2x = 30m + 20m + 10sm;C.leptophylla: 2n = 2x = 30 = 24m(lsat)4sm (lsat )+ 2st;C. yunnanensis:2n = 2x = 30 = 18m + 10sm +2st;C,pitardii: 2n = 2x = 30 = 18m + 12sm.Nine of them were reported for the first tine.Karyotypes were very sinilar each other among the above species, and comprision between sections was more important than rhat bitween species

Key words: Camellia, Karyotype

摘要： 本文报道了 9种 2变山茶属植物的核型．结果如下：Camellia henryana: 2n＝2x＝30＝2lm+8sm+lst;C．furfuracea: 2n=2x=30=20m＋10sm；C.wardii：2n＝2x=30＝8m＋11m＋lst；C．anlungensis：2n＝2X＝30＝19m＋9sm＋2st；C．anlungensis var．acutiperulata: 2n＝2x＝30＝19m十2st；c．pyxidiacea：2n=2x＝30=20x＋8sm＋2st；c．pyxidiacea var.rubitubderculata;2n=2x＝30＝2lm＋8sm＋lst；C.breuistyla: 2n＝2x＝30＝18m+10sm+2st；C．leptophylla: 2n=2x=30＝24m（lsat）＋4sm（lsat）＋2st； C．yunnanensis: 2n=2x＝30＝18m＋10sm＋2st；C．pitardii：2n=2x＝30＝18m＋12sm．其中，前 7种 2变种的核型为首次报道，比较前人的有关研究可以看出上述核型在种间较相似，以组为单位进行比较比种间比较具有更大的意义。
