Abstract
Chromosome numbers and other karyological data for ten Stemona species and for Stichoneuron caudatum are presented, including first reports for Stemona burkillii, S. involuta, S. mairei and S. phyllantha. All investigated taxa
of Stemona exhibit n = x =7 (2n =14) chromosomes. For Stichoneuron caudatum an earlier count revealing 2n =18 is confirmed. The observed chromosome lengths range between 0.9 and 6.9 μm (largest chromosome in Stichoneuron caudatum). Additionally,
the genome sizes of seven Stemona species and of Stichoneuron caudatum are reported. The obtained results are compared with literature data and discussed.
