From Guyana, Brazil, Colombia, Venzuela and Peru as a small to medium sized, hot to warm growing epiphyte that loses its leaves in the winter so it needs a definite rest. When the new growth appears and is more than 2" it is time to water and fertilize heavily, as the leaves yellow in the fall it is time to slow watering to a trickle. They bloom in the spring, summer and fall on a suberect to pendant, 1 1/2' [45 cm] long, many [20] flowered, racemose inflorescence arising on a mature pseudobulb and have fleshy, fragrant flowers and are a hot to warm growing species requiring very bright light. They have oblong-fusiform pseudobulbs enveloped basally by several leaf-bearing sheaths carrying membranous, oblanceolate or lanceolate, distichous, deciduous leaves that sheath the pseudobulb and are 14-16 inches in length, the inflorescence is basal, erect, and single sexed, with male or female flowers.
