Identification: Can you identify this plant?

I have a small tree,approximately 3 years old.I forgot what it is.An evergreen with bipinnate glossy leaves.Seven leaflets at one stem.Hope the picture is enough for identification.

 

Compare with Zanthoxylum.

I checked the pictures of Zanthoxylum but my plant's leaves are not serrated,notched like Z.

 

Not all species are dentate/serrate and not all species (or specimens)are prickly.

Dear Saltcedar:I still hesitate to name it because Zanthoxylum is not common in our country.I always collect edible exotic plant seeds but I am not familiar with Zanthoxylum.I suspect if its an anacardiacae specy.
I always write over the pot,but sometimes when seed germinate lately,pot soil is used in another pot and I cannot able to follow it!
