all the botanical references I've read say NO Difference between C. coreana and C. turczaninowii. They are one and the same species. The names are synonyms. What difference were you expecting? To me that indeed looks like C. coreana. And it looks like C. turczaninowii, because they are the same thing.

Thanks for the input, I thought they were slightly different? The long pointed leaves threw me, I thought KH was more of an oval shape.

Okay, makes sense, now that I know what you are looking for. I believe this is natural variation between individual seedlings and possibly some biogeographical variation depending on where seed was collected. One would have to have a dichotomous botanical key and do a close examination, to be absolutely certain, but just superficially, from your photos, I'd say it was correctly labelled. And depending on which author you look at, it is about 50:50 as to which of the two names gets used. Slight favor to Carpinus coreana because it is easier to remember how to spell.

Once again, I think Leo's right.

Some consider C. turczaninowii as a subspecies of C. coreana, but the matter is yet to be settled among dendrologists.

I believe this is natural variation between individual seedlings and possibly some biogeographical variation depending on where seed was collected.
I tend to share this opinion.

I'd like to also add that different cultivation environments (soil, climate, ferts or not, etc.) can make a big difference on rather young potted trees. Had you asked for ID without mentioning "Ulmus", I might have suggested "Zelkova ?..."
