Karyological studies on 16 species of Vicia L., including 10 species from the Egyptian flora are presented. Chromosome counts are observed for two species for the first time (2n=10 in V cinerea and V nigra). A diploid number of 2n=10 (x=5) has been found in 4 species, 2n=12 (x=6) in 2 species and 2n=14 (x=7) was recorded in 10 species V. hirsuta was found to have 2 B-chromosomes. The karyotype in the examined species is more or less symmetric. However, considerable variations exist in chromosome size among the species studied. The results of the present study con-firm that x=7 may be considered the basic number in the genus.
