Catasetum is a genus of orchids that includes approximately 160 species distributed throughout tropical and subtropical regions of Central and South America. These plants are known for their distinctive flowers, which are characterized by their showy, often brightly colored, petals and sepals. The lip of the flower often has a fringed or ruffled appearance, and may be shaped like a pouch or beak. Catasetum orchids are also notable for their unique mechanism of pollination, which involves the explosive release of pollen that is triggered by the visit of a specific pollinator, such as a male euglossine bee.

Catasetum orchids are typically epiphytic, meaning they grow on other plants rather than in soil, and require bright, indirect light and high humidity to thrive. They are popular among orchid enthusiasts for their striking appearance and the challenge they present in cultivation. Many species of Catasetum orchids are endangered due to habitat loss and over-collection, highlighting the importance of conservation efforts to protect these remarkable plants for future generations to enjoy.
