Two natural cytotypes of the Nothoscordum montevidense complex are described for the southeastern region of Buenos Aires province, Argentina. The cytotypes are 2n = 6x = 24 and 2n = 8x = 32 with metacentric chromosomes (m). Cytological and morphological evidence indicates that these cytotypes belong to N. montevidense ssp. latitepalum, although this subspecies is 2n = 4x = 16m. The probable origin of these cytotypes is discussed.
