The number of chromosomes in metaphases root meristems of Erigeron canadensis L. (2n= 18) and E. annuus (L.) Pers. (2n=27) was determined. The chromosomes of both species showed a morphological differentiation - they were heterobrachial or isobrachial; E. annuus had an additional unpaired isobrachial chromosome
