You'll need to have an eagle eye and look high in the tree to spot the fruit of the osage orange in this picture. There are at least 5. Can you find more than that? This picture was taken in August 2004. The trees are part of a hedgerow south of parking lot 7 at Morton Arboretum. Although I wasn't able to find an accession tag, the data base lists an accession tag for 808-54 and shows 20 trees at B-102/area (but I think that they are just slightly east of that).
