I was told last year (2011) by a well known photographer friend that he saw and photographed Bulbophyllum pachyrachis in Fakahatchee.
He won't say where but he said its there.
I'm sure the lost orchids are still there but keeping themselves out of sight. Remember....Fakahatchee is a big place and not all of it gets visited frequently....and not all the orchids grow in the same habitats....i.e. Not all grow in the sloughs.
