Abstract Alstroemeria is a genus endemic to South America, with wide distribution in Brazil and Chile. There are many taxonomic uncertainties or species complexes that make its taxonomy complicated. This of enormous importance ornamental horticulture one the most important as cultivation cutting plants. In Chile, there 39 11 complexes, being them werdermannii, which presents two geographically separated varieties recognized for their distinct flower morphology coloration differences. The chromosomes from both (var. werdermannii var. flavicans) were compared. Chromosomes measured assistance software MicroMeasure 3.3. For each population analyzed (10 metaphase plates), intrachromosomal asymmetry index MCA interchromosomal CVCL used. data obtained this investigation indicate three populations A. have same karyotype, i.e. 2m + 2sm 2st-sat 2t-sat. No differences chromosome architecture found among varieties. means set all identical, independent variety; yet, different makes it possible recognize
