Abstract

The karyomorphology of Podophyllum hexandrum Royle (2n=2x=12) is described for the first time. The haploid set comprises one metacentric, three sub-metacentric and two acrocentric chromosomes. Metacentrics are the longest and acrocentrics the smallest in the complement. Secondary constrictions are located in the short arm of two meta-/submetacentrics and in the long arm of the two acrocentric chromosomes. The number of NORs is in agreement with the number of nucleoli organized per root tip nucleus.
