Etude caryologique de deux populations de Lygeum spartum L. (Gramineae) de l'Ouest AIgérien
Karyotypes oftwo populations of Lygeum spartum L. from different algerian localities are presented. The first population which grows in semi arid coastal region has 2_n_ = 4x = 40 and the second one, which grows in arid high plateaus, has 2_n_ = 2x = 16. The basic numbers are: x = IO and x = 8 the latter of them has been found for the first time in the species studied.
