If the leafs are lobed,rounded, it's a white oak. If the leafs are oval with spines on the edges it's a saw oak. That acorn looks like a saw oak acorn to me. Saw Oak is an Asian imported tree. Was brought to US because it grows fast and produces a mast crop in 5 years as compared to 20 for a white oak. Deer and turkeys and any animal that will eat an acorn, will eat a saw oak acorn.

Now where is this tree at and do ya need any help with this hunt???
