Location: Lincoln County, Oklahoma
SOLVED: Thorny-Green Vine, Black Berries and golden leaves
There are a couple similar vines, but this one is pretty common.
The leaves on the Similax auriculata are too narrow. The more likely candidate is Similax bona-nox:
melody, you are right that it is a Smilax. However, Similax auriculata does not grow natively in Oklahoma.
It is, defintely a smilax. I went to some Bilogical surveys of Oklahoma done by Oklahoma University. I would suppose they would be the 'authorities' on the subject. Although MUCH of what universities learn is methodically kept secret (especially archaelogical data) I did find some biological surveys of Oklahoma. Problem was, the two I found, both by OU, did not match. They had different species on both! While some species such as Blackjack and Post Oak (Which if you did not include those in Oklahoma you might as well call yourself an amateur and not a University Proffessor) were on both, most were not congruent. While I am not putting down all University work, It does distress me that the surveys lack some common species like an extremely common cactus I see in the woods, which is completely absent.
Anyway, long story short, the species listed overall, are:
I believe the one in the picture is Smilax bona-nox. Thanks for pointing me in the right direction!
The USDA lists a couple more Smilax species:
The Oklahoma Vascular Plants Database is upfront about being "..far from complete.", and plants aren't represented unless there's a voucher specimen in a state herbarium. It's a huge undertaking and there's probably not a lot of money for this kind of effort.
There's an oak tree in a park in Maryland that has had the name tag changed several times! Some oaks are extremely difficult to ID, even comon ones.

Well I'm happy to hear that in a way. At least I am not the only one who thinks they got it figured out and then relizes there wrong!
There's always some look alike, or something.
And I understand about it bieng far from complete. I am just frustrated about these extremely common species, not being mentoined anywhere online for Oklahoma.They do a good job with the trees, virtually every site saying Post oak and Blackjack oak (as well as a couple others) are what you are GOING to see. Then, after making that clear, they provide a huge list of other possible trees that you MIGHT see. I wish they would do that with the other plants. For example, If you go to any forest in central Oklahoma, you are not only GOING to see the plant I have above, you are going to be surronded by it.
