Abstract

Meiosis was studied and gametic chromosome numbers were determined for seven species belonging to 5 families. These were: Anthemis deserti, n = 9, Launaea capitata, n = 9, and Rhanterium epapposum, n = 6. (Compositae; Moltkwpsis ciliata, n = 6, (Boraginuceoe); Haplophyllum tuberculatum, n = 9. (Rutaceae); Gypsophila antari, n =17, (Caryophyllaceae); and Phntago coronopus,n = 5, (Plantaginaceae). Meiosis in all species studied was generally regular with the formation of bivalents and in some cases univalents at diakinessis, but having a low chiasma frequency per bivalent.
