The vine in the photo above has finished blooming and is beginning to set its fruit. The Wild Cucumber, Échinocystis lobé in French or Echinocystis lobata [ak-in-oh-SIS-tiss low-BAH-tuh], has a fruit that appears a bit like cucumber on the outside.
The photo is of the male or staminate flowers. The female or pistillate flowers are smaller, more inconspicuous and fewer at the base of the male flowering stalk.
Here is a photo of the fruit. Until a few minutes ago I thought it was mostly full of air and empty space as that is how it looks later in the fall. However, I just went out with a scalpel and the camera and found that the inside is full of a very loose, foamy like material that surrounds the four large seeds.
This last photo is of the tendrils which are many and really hang onto what ever tree or shrub the vine chooses to climb and stick to.
