%X This paper investigates the chromosome numbers and karyotypes of two species of Dieffenbachia . The result shows that the karyotype formula of D. daguensis is K (2n ) = 2x = 34 = 12m + 18sm+ 4st , which is of 3B type with As·K% = 66.52% ; the karyotype formula of D. maculata is K (2n ) = 2x = 34 = 2M+ 28m + 4sm, which is of 1B type withAS·K% = 55.38% . Compared with the more advanced members in Typhonium and Sauromatu, the karyotype of Dieffenbachia is rather primitive, and the karyotypes of Araceae are rather diverse .
