ORIGIN: This large sized, hot to cool, pendulous growing, terete-leafed epiphyte was collected in Belize but they can be found as epiphytes with an ascending simple or branched raceme with small, successively opening flowers on trees in swamps, open mountain forests, pastures and coffee plantations at elevations of 300 to 1500 meters in all of Central America, Colombia and the West Indies.
DESCRIPTION: This large sized, hot to cool, pendulous growing, terete-leafed epiphyte was collected in Belize but they can be found as epiphytes with an ascending simple or branched raceme with small, successively opening flowers on trees in swamps, open mountain forests, pastures and coffee plantations at elevations of 300 to 1500 meters in all of Central America, Colombia and the West Indies. Please note that while the plant is pendant growing the inflorescence is basically erect to lateral so mount on treefern or wood accordingly, give bright light, high humidity and year round water with less when mature. This orchid has small inconspicuous pseudobulbs carrying a single, apical, terete, thick-fleshy, long leaf and blooms in the spring on an erect to lateral, racemose, to 6" [15 cm] long, several to many flowered, racemose inflorescence arising on a mature pseudobulb.
FLOWER SIZE: 3/4 -- information provided by Jay Pfahl, author of the Internet Orchid Species Encyclopedia (IOSPE).
