本文研究了5种山茶属植物的核型。结果表明，这5种植物都是二倍体，核型分别为马关茶C.makuanica 2n=30=22mm+8sm；厚轴茶C.crassicolumna 2n=30=22m+85m；广南茶C.Kwangnanica 2n=30=22m(2SAT)+8sm;假秃房茶C.gymnagynoides 2n=30=22m+6sm+2st；圆基茶C.rotundata 2n=30=20m(2SAT)+10sm(2SAT)。厚轴茶和圆基茶的核型为2B型，其余3种为2A型。本文还对茶组(sect.Thea)植物的核型作了讨论。圆基茶和广南茶的核型为本文首次报道。

The present paper dealt with the karyotypes of 5 species of Cameilia by wall degradation through hypotonic treatment and flame-drying method.According to the classification systems given by Li Maoxue et al.(1985),the karyotype formula of C.makuanica was 2n=30=22m+8sm,C.crassicolumna 2n=30=22m+8sm,C.kwangnanica 2n=30=22m(2SAT)+8sm,C.gymnagynoides 2n=30=22m+6sm+2st,C.rotundata 2n=30=20m(2SAT)+10sm(2SAT).karyotype asymmetry demonstrated that C.kwangnanica,C.makuanica and C.gymnagynides belonged to 2A type of Stebbins karyotype symmetry;C.crassicolumna and C.rotundata was 2B.karyotypes of C.rotundata and C.kwangnanica were firstly reported in this paper.The karyotypes of Sect.Thea were also discussed.
