In The Garden: What kind of holly is this?

If anyone can identify this holly for me, I would be thankful. I have four different hollies in my yard and this one is the only one I haven't been able to identify.

 

Looks like Ilex cornuta.

I'd go with Ilex cornuta too, but don't entirely discount I bioritsensis, I. pernyi or hybrids between those species. Would really need to see the flowers and fruit to be sure.

 

Thank you very much. I am so happy for your help. I just need to wait to observe the fruit and flowers and then I can follow your advice in fine-tuning the identification.
