SUMMARY1. Meiotic chromosomes of seven species of the genus Rubus (x=7), two species of Spiraea (x=18) and one species of Potentilla (x=28) have been studied (vide Table 1).2. Spiraea and Potentilla species are tetraploid and octaploid respectivelly while all of the species of Rubus are diploid.3. Extranuclear bodies are seen in some species of Rubus and are non-chromatic.
