ResumoThis paper deals with the cytology of 14 species comprising 8 genera of Epidendreae. The genus Pachystoma (P. senile: n=20) has been investigated for the first time. B-chromosomes are reported in Calanthe puberula (2n=40+1B) and Pholidota articulata (n=20-0-3B). An aneuploid race of Eria confusa (n=18) is discovered. The chromosomes in Pogoniinae, Thuniinae and Bletiinae are larger in size compared to htose of Coelogyninae and Epidendrinae which are relatively much smaller.
