Need and ID on this ..

If i remember right i was told this was a grandpas beard.. they grow as a very long vine climbing trees to about 20 to 30 feet high .. i know you have to be carefull with the seeds as you dont want them in your yard .. they take over..
i would just like an ID on it as i posted this pic on a photography forum and they all really liked it so i would just like to give an exact name ..

thanks in advance for any help ..
