Answer: They do look like a cuke on the vine, but I think they are a lighter green shade. Luffa acutangula is an edible gourd that is very common in Asia. It is shaped like a cuke, but has very distinct ridges. The bottom is wider than the top. There are other varieties that are smooth, such as Luffa cylindrica. If picked when young, it can be quite tasty, but when it matures, the interior becomes hard and stringy--what we know as the sponge. Luffa has a light yellow blossom that blooms during the day. I hope this helps with your mystery!
