Plant identification was aided by Dr. Franco Pupulin who stated that the plant is not O. montealegreae. The flowers don't match O. montealegreae and the plant habit looks different. This plant most closely resembles O. dolabratus. O. dolabratus is from Ecuador and is very similar to O. aristatus which is from Panama. O. aristatus has a different column shape with wings at the base and a small cluster of papilose structures, which are not evident on this plant. The O. dolabratus photo in the IOSPE is a close match.
