摘要：
Natural hybridization has often been recorded within certain genera of orchids, one of them is Catasetum. During a field study in a forest de igapo in Brazilian Amazon, a new natural hybrid was found, it is here described as Catasetum x sheyllae. Its morphological features, mainly the structures of the lip, are intermediate between those of its putative parent species, C. boyi and C. garnettianum, both observed in sympatry.
