ID these acorns

on page one but its hard to call it without seeing bark too cause that always gives it away

The pic with three leaves is overcup. All three leaves came off of same branch.

I can tell you one thing, I have seen a many a blackjack leaf that would pass for a water oak all day long.

One thing is for sure, those acorns fit the bill perfectly for blackjack oak acorns.

Here's another option.

Dr. Evans, dendrology instructor, said it could very well be a nuttall X water oak hybrid as the acorns show distinct features of both. Given the location and the fact that leaves don't appear to be leathery, he ruled out blackjack.

Got a tree question for the experts. I am not that familiar with hill species so this may be a very elementry question. At what age do white oaks start to produce acorns? Reason I ask is I have a white oak in my yard that I planted about 6 years ago. It made a lot of acorns this year. Made some last year as well (at 5 yrs old). No doubt it is a white oak, no need to question the species, just want to know if this is common at all? Very nice sized acorns. It is growing in some "3 bale cotton dirt" which may also add to the advantages this tree has. Full sun, no shading, within a couple of feet of concrete driveway. Some water does run off the drive in the direction of this tree, but otherwise it has had no watering other than rainfall. What is the germ rate on white oak acorns? Thinking I may like to market these seedlings as "fast growing/early producing" white oaks. Is it in the genetics for seedlings from this tree to perform similar OR is this just a case of great growing conditions?

On the questions about the acorns/leaves, I say it is a water oak. Some of these older CRP trees are in good dirt with little competition and are at the size where they are getting everything they want and not quite competing with the next tree down the line yet. Some of these trees are producing a lot of acorns and very good quality as well. Hard to judge the size of the acorn in the picture. They do look a little large for water oak, but I am assuming the growing conditions and age of tree are the reason. I see stripes on some water oak acorns and the stripes are more prevelant on some. A hybrid cross makes a lot of sense too. Never know they could cross? Looks like we would have hybrids all over the Delta if nuttall and water oak could cross and I guess we may have???

You and this Evans fellow can kiss my COUNTRY WHITE... nope I'm gonna control myself. One, two, three, what the heck is wrong with me.

Red oak species do hybridize fairly often. Not that its common, but enough that its not extremely unusual. White oaks - not so much.
