Somatic chromosomes of Oncidium morenoi and O. pumilum were analyzed in detail. The chromosome number of O. morenoi and the karyotypes of the two species are presented for the first time. O. morenoi showed 2n=30 with a karyotypic formula of 14 m + 14 sm + 2 st. O. pumilum presented 2n=30 and a karyotype composed of 20 m + 10 sm.
