Abstract: The karyotypes of 3 species of Ceratoides (C. arborescens,  C. ewersman- niana and C. latens) were studied. The results show that C. arborescens is a diploid, with karyotype formula 2n=2x=18=16m+2sm,  C. ewersmanniana is also a diploid,  with 2n=2x=18=14m+4sm,  while C. latens is a tetraploid,  with 2n=4x=36=24m+12sm. Ac- cording to the karyotypes,  the morphological features and geographical distribution,  C. arborescens seems to be a primitive species and it might have originated in northern China. C. arborescens and C. ewersmanniana are similar to each other,  not only in mor- phology but also in karyotype,  which shows that they are closely related and that C. ar- borescens might be the progenitor of C. ewersmanniana. The karyotypes of the 3 speciesof Ceratoides are basically identical,  with only minor differences.Decontaminated thianthrene disproportion.
