Two new species of Epistephium (Orchidaceae, Vanilloideae) from Colombia

Abstract Two new species of Neotropical Orchidaceae, Epistephium epiphyticum Szlach. & Kolan. and E. cardonae Szlach. & Kolan., are described and illustrated based on Colombian material. So far the new entities are known exclusively from the type locations. Both species are placed within a key to Colombian Epistephium Kunth.
