identification of mystery tree

[Alexander Krings]

Dear All,

I write to ask for potential help with the identification of a
specimen we recently received.  The plant was collected from a yard in
Wake Co., North Carolina, and does not seem to match anything in our
native flora (or are we overlooking something?).  The grower indicated
that it volunteered and is currently about 5 feet tall.

Description: stems greenish, the pith solid, white, hard; buds
extra-axillary; leaves imparipinnate, of 7-9 essentially sessile
leaflets, margins dull-serrate to bi-serrate, apices acute to
acuminate, the extreme tip rounded, rachis grooved to ribbed.

Images can be found here:

No fragrance could be detected from crushed leaves, rubbed rachis, or
cut stems.

I had initially thought something in Sapindales, but could not find a
match in our collections.

Thank you in advance for any help anyone could provide.

Best regards,

Alexander
