Abstract Catasetum has neotropical distribution and its diversity center is in the Brazilian Amazon. Spite of, Colombia being one of the richest countries in orchid flora, also it has been one of the least explored. For this reazon, the objective of this research was to understand the diversity, distribution, conservation and species with potential use in commercial cultivation of Catasetum to Santander Department and Colombia in general. 14 species and a new report for Colombia, C. tenebrosum were recorded. These plants have undergone a process of cultivation and domestication, for the material preservation and propagation, with the aim to manage private collections and marketing. The Catasetum distribution and inter-species wealth is mainly related with municipalities of the interandino Middle Magdalena Valley, stands like ecological niche modeling, adding the Eastern Cordillera, Occidental flank in the region of Piedmont, between an altitude ranges of 50 to 1000 m. It marks the distribution and altitudinal range C. lucis, Santander exclusive specie. In this study the C. tricorne native populations were not found. In conclusion, the Santander Department has the greatest diversity of Catasetum in Colombia, so it can be considered a species conservation center in situ and ex situ in the country.
