Mitotic and meiotic chromosomes of Caryophyllaeus laticeps (Pallas) from Rybinsk reservoir were studied using air-drying techniques. it was established that the diploid set contains 20 metacentric chromosomes. The chromosomes are large - their mean absolute length ranges from 3.00 to 12.90-mu-m. The last pair of small homologues comprises only 3.4 % of the total length of the complement. One specimen of C. laticeps with 2n = 21 (trisomic after the last pair of chromosomes) and one triploid specimen with 3n = 31 is described. Data on the comparative karyology of caryophyltids are discussed.
