You all led me to the right ID with the Chinese yam, now I have aother new arrival that needs a name.

I just found it a few days ago while hand pulling some honeysuckle...here goes:

It's a vine, and it is studded with small almost thorn-like structures that obviously enable it to climb...in fact it feels sticky to the touch. The leaves are coarse on both surfaces, lack any lustre and are serrated at the edges. The leaf structure is exactly that of a sassafeas tree: one palmate, one tri-lobed and one with a "mitten" appearance.

Could this be some kind of grape? It certainly is not the usual variety..I have those everywhere and they are very shiny, waxy leaves, and the vines are more woody in older plants. When I first touched it I could not believe how sticky it was to the feel.

Haven't crushed any parts and had a smell...guess I should do that.

Any ideas?

Only one like it I see out there, and it's a new sprout. MAybe it's a good thing....
