"This small, repent species is frequent on the eastern slopes of the Andes in central Bolivia. It is characterized by a slender, branching rhizome that bears at intervals short ramicauls with narrowly elliptical, petiolate leaves. The few-flowered inflorescence sometimes does not exceed the leaf. The flowers are usually dark purple; the petals, three-veined; and the lip, type A with a rounded callus on the dorsum."
