Abstract: Using the common slice-making method, the karyotype of Schisandra propinqua(Wall.)Baill. was analyzed for the first time. The results showed that S. propinqua is 2n=2x=20m+8sm, the constitution of relative length is 2n=28=2L+14M2+8 M1+4S and ratio of the longest chromosome to the shortest is 2.14. In addition, its karyotype belongs to 2B type, asymmetry index is 0.59. Secondary constriction and satellite are not found. The feature of karyotype suggested that S. propinqua should be relatively advanced in Schisandra Michx..
