What is the correct spelling of a tree called terriendra?

Question

I heard the name of this tree and I've tried to spell it phonetically here, although I might not have heard it correctly. From what I gather, it grows in both Oregon and El Salvador. I've already tried several spellings on Google, but I'd really like to get the opinion of a real person. I would appreciate any leads that would help me identify this tree that I heard the name of. Thanks in advance.
