Need nut tree ID

My family say these are chestnut trees, Are they ??

 

Looks very much like Carya cordiformis,(Bitternut)

 

Ditto to Carya cordiformis (Bitternut Hickory); if not that, then Carya illinoinensis (Pecan).

 

i would vote pecan

here is a link with bitternut http://www.cnr.vt.edu/DENDRO/dendrology/syllabus/factsheet.cfm?ID=18

and one with pecan http://www.cnr.vt.edu/DENDRO/dendrology/syllabus/factsheet.cfm?ID=198

fruit and leaves look like pecan

 

I ruled out Pecan.The fruit is more elongated and has the raised ridges right to the top, while Bitternut has wings that only extend to the middle.Pecan leaves are distinct in having 11-15 leaflets per leaf ,while Bitternut has only 5-7.Pecan nuts are delicious,whereas Bitternut 's other common name is Pignut!!!!I hope this helps.

 

I agree not Pecan, I'm surrounded by the D**n things.

Chris

 

Thanks everyone.. Sad to say, but I agree it is Bitter (yuk) nut.. would have been nice to be pecan.. I love pecans.

 

You should have other Hickory species about, Shagbark for instance....they are much better to eat than Bitternut.

 

Haven't seen any, will keep an eye out though. My dad has a Walnut tree, but did yeild much this year, and the squirrels got them.. Maybe better luck next year, with some pruning perhaps the tree will have a better crop next year.
