This is an epiphyte from a wide area of central and western Africa. It is related to Calanthe and Spathoglottis. I grow it in the greenhouse, and it has been doing nicely. Based on the information about its range, it probably could be grown somewhat cooler. If I had another one I'd experiment with outdoor growing, but I"m not going to risk this one... I'll post additional pix when more of the flowers open.
