During the present study meiotic investigations are carried out on some members of family Convolvulaceae collected from different regions of Rajasthan. Total 19 species under 6 genera are meiotically studied. Of these, 2 species, namely, Convolvulus deserti (2n = 18) and Merremia umbellata (2n = 14) are cytologically worked out for the first time from the world and five species, namely, C. glomeratus (2n = 28), C. sabatius (2n = 22), Ipomoea cordatotriloba (2n = 30), I. triloba (2n = 30) and I. sagittifolia (2n = 30) are cytologically worked out for the first time from India.
