The article studies a new method of making chromosomes by callus and bud, and analyses the karyotype of Campotheca acuminata Decne. The results demonstrated the chromosome amount to 44. The karyotype formula is K_((2n))=44=2M+32m+2sm+8T. Among them, 1pair is median point (M),16 pairs are median region (m),1 pair is submedian region (sm), 4 pairs are terminal point(T),belonging to"2B" type.
