Abstract
In Colombia, four species of Triphora (Orchidaceae) are recognized. Two species (Triphora galeanoi and T. vichadaensis) are newly described. As circumscribed here, the two new species occur exclusively in Colombia apart from T. foldatsii, being known from Colombia and Venezuela, and T. gentianoides, ranging from the USA (Florida) in the north to Colombia in the south. For the species treated, a taxonomic description, synonymy and information about distribution are provided. Additionally,for the two new species, illustrations of flower parts are provided. A key for the determination of the Colombian species of Triphora is included.
