I found this plant in the wild grassland of North Texas. It has small thorns, purple flowers and little fruits. The seeds of the fruits have a slighty hot taste to them. Dried they smell like dried tomatoes. The seeds inside are bunched together around the stem like a bell pepper. The black discolored ones on the right side of the picture were infested with a single fruit fly larva in each fruit. They were all quite dry except the ones infested with the fruit fly larva. Those were completely full of black wet larva excrement (future fertilizer for when the fruit drops?) and the seeds were not eaten by the larva. If the seeds of the larva infested fruits are still viable, it could be considered a symbiotic relationship as opposed to a parasitic one. I noticed that the little fruits with only a few seeds had a little larva in them and the big fruits with lots of seeds had a big larva in them. This probably means that the egg is laid early in the fruit's life and that the plant is able to keep the fruit alive and growing, thus feeding the larva too.

i've seen that particular fruit before don't remember offhand which it is. btw, these are all pretty deadly poison so it's a good idea never to sample things unless you are 100% sure of what it is.
The stripes you see on the fruits are actually on there like a watermelon. It's not a leaf like on the ground cherry. Mine are green with purple flowers, the nightshades are black with white flowers. Neither the ground cherry nor the nightshade have thorns, mine does.

I would have to wait until monday as I don't have the plant here.
yes, i didn't mean it was either of the particular plants that i linked you to, just giving you a place to start. as ecrane said, there are many species within each genus...but i still wouldn't eat them.
I believe these are from Solanum carolinense L., or "Carolina Horsenettle. Here is a link to some pictures of the fruit you show in the picture you produced. There are also pictures on there of the plant and its flower. Hope this helps.
