Cytogenetical studies were conducted on Ledebouria botryoides. We reported 2n=60 (15m+10sm+5st) chromosomes. The karyotype was asymmetrical and fell into the 4B category of Stebbins’ asymmetry classes. Two groups of chromosomes were observed, i.e. 15 pairs of long chromosomes (2.82–6.65 µm) and 15 pairs of short chromosomes (1.67–2.80 µm). Two chromosome pairs had a satellite on the short arms. The meiotic course was found to be normal with n=30 bivalents.
