Dear Dr. Hill:
My son is trying to identify a vine growing in our wooded yard. It has a light green stem about 1/2 inch in circumference with a knob/joint about every foot. At each knob there are some bright green tendrils and a single tiny leaf that is facing upwards and is sort of hollowed out. The leaf is thick. Along the stem there are brown thorns with green tips, but they are rather flexible and not particularly sharp. We measured it at just over 12 feet today and we measured it at 8 feet six days ago , so about 4 feet in the last week. He is calling it the rocket vine, but would like to know what it is really called. Thanks in advance for your help.

Please send more pictures. I need to see more of the plant especially the leaves, and not quite so close up. Thanks
