'Amazing Encounter'

‘Amazing Encounter’
I am assuming these are some version of Angel Trumpets. We were told by some local fishermen on a recent river tour that if we wanted to photograph some unusual flowers they knew a spot we could go. The catch was that these flowers only bloomed at night and for one night only and by the next morning they wilted and were gone. This seemed far fetched at first and maybe a wild goose chase with these guys having a good laugh at our expense. We were further told that the large bush or small tree would bloom for a week or so with only a hand full of blossoms opening each night during that period. Well it was all true and this is one of the images to prove it. We actually watched these blooms open over a 30 minute period shortly after sunset and it was amazing. These are very large blossoms close to the ground and the leaves showing are part of the plant. The blue flowers were from another separate plant that was sharing the ground space. The side light is from the bow spotlight of the boat that was used for focus light and to illuminate the path made for the short distance into the woods we had to maneuver. The next day we returned and by mid-morning the blossoms were laying wilted on the ground. One shot, very slight crop. Any insight about these flowers from the experts out there would be greatly appreciated.
