"This small, scandent species is characterized by a stout, branching rhizome with short, ascending ramicauls with elliptical leaves and an erect inflorescence about twice as long. The three sepals are concave and markedly thickened, especially toward the apices, and with the lateral sepals antrorse. The petals are 3-veined. The trilobed lip is similar to that of the frequent, widely distributed Stelis elongata Kunth." Luer 2017
