UQB: Unidentified Quiet Blossom

I think this is some sort of nut tree and the closest I could find to the leaf shape was a cashew tree.  I found one picture that showed it with a star-shaped flower, but in other pictures, the petals were more rounded.  I think my friend told me this was an almond tree, but it definitely isn’t an almond.  Once again, if you recognize it, please educate me.

This non-assuming little flower deserved some extra attention. As with most things in nature, close up, it makes more of a statement.
