Here's a nice photo I got off of a Sobralia that I've had for nearly 10 years and only started blooming a few years ago. I hadn't been able to ID it for the longest time. But I think I may have found a match in Sobralia warscewiczii. Anyone who might know more about the genera than I, please feel free to chime in and let me know what you think. It was found on a fallen branch of a pretty big tree in northern Costa Rica.
