Hello all, I'm new to this. I stumbled across these plants while walking along a drainage canal here in the New Orleans area. The vine looks just like a cucumber, with the same yellow flowers and prickly vine. The fruit smells very much like a cucumber too. I have looked all over to try to distinguish this plant from others, but found nothing definitive. Perhaps it is some kind of hybrid.
Image is four successive snapshots from slightly varied angles. The three fruits pictured are from the same plant but were different colors. Thanks for the help. I would like to know if I can eat these should the gas prices rise again.
