Abstract :
Karyotypic observations showedthat 4 speciesincluding O.scorbiculata, O.melanotricha, O.aucherisubsp. teheranicaand O.oxypterahave 2=16 chromosomes and according to the basic number of x=8, they are diploids. O.oxypterahas got the least total length (31.o7) and average chromosome length (3.88) but the most TF% of 36.43% whichrefers to itsmostasymmetricalkaryotype. The karyotypescanbedivided as lA(O. scorbiculataand O.melanotricha), 1B (O.aucherisubsp. teheranica) and 2B (O.oxyptera) due to Stebbins classification.
