A couple more for possible ID
The first epi is in large plants that can be more than 5' tall and have thousands of flowers. The second has thin triangular PB's that stand about 6" tall. There is a reed stem with almost identical flowers. (It is not werckleyi. It has no lip to be noticed)
I just uploaded some pics to the gallery. Otoglossum chiriguense was the most exciting find. I saw it from more than a hundred feet away. Most of them are not yet identified.
