The diagram gives the frequency distribution of haploid chromosomal numbers in 17,000 flowering plant species. The values range from n = 2 to n = 250 (W. GRANT, 1963). A collection of chromosomal numbers, as well as further information about single plant species can be found on the server of the Missouri Botanical Garden – w3 – Tropicos-project at
