Hi guys. I live on a farm in southern arkansas near Hope. In our meadows we have found about 10 trees that have tons and tons of bunches of small dark reddish "cherry" looking fruit. Its yellow/orange inside, and is sour to the taste. Longer they sit on the ground, softer and less aour they are. If anyine has any clue as to what this may be, PLEASE help us out! We picked 10 pounds already in case its worth keeping.
