A Knotty Vine

I found this wild wisteria bush near where I live today. That whole tangled mass in the middle are the twisted trunks of wisteria. It appears that a wisteria vine descended from a tree, now long since gone, put down roots, and then had other wisteria plants grow up around it. You can see the old trunk of the original wisteria vine at the bottom of the most twisted part. Almost everything you see in this picture is part of a wisteria vine, except for the oak tree just left of center. All the other branches and "trees" you see, including the one cutting across in front, and the thick on at an angle on the right is part of one massive wisteria vine. It was an impressive sight to see.

For reference this is a picture of the spot I was standing when I took the picture of the wisteria. You can see the tangled wisteria on the left side.
