Cytogenetical studies in garden cultivars of Amaryllis vittata, Narcissus tazetta, Hemerocallis aurantiaca and H. fulva revealed their existance as different cytotypes. The karyotype was symmetrical in all these excepting N. tazetta which showed an asymmetrical karyotype. The role of chromosomal repatternings and hybridization is evident in the evolution of these taxa. Irregular segregation of small chromosomes probably accounts for the aneusomatic cells in Hemerocallis aurantiaca and Amaryllis vittata (cultivar 'b'). The following karyotypes were established:Amaryllis vittata L.:cultivar 'a'-K(2n)=22=Bst4+Bsm2+Csm2+Cst4+Dst2+Em4+Esm2+Est2cultivar 'b'-K(2n)=44=Bsm2+Csm2+Cst14+Dst9+Em7+Est1+Fst2Narcissus tazetta L.:pale-yelow cultivar-K(2n)=32=Cst5+Dm1+Dst4+Dt4+Est3+Fm1+Fsm1+Fst13dark-yillow cultivar-K(2n)=30=Cst2+Dsm2+Dst10+Esm2+Est3+Fsm2+Fst9Hamerocalis aurantiaca Bak.:K(2n)=33=Em3+Et1+Fm3+Fsm17+Fst3+Gm2+Gsm4H. fulva L.:K(2n)=22=Em2+Esm2+Fm3+Fsm4+Fst8+Ft2+Gm1
