The other possibility is Senna didymobotrya, an African native that has naturalized in many locations. (I get these two species confused. I do not often see S. alata in the USA; it does not grow easily in California, but S. didymobotrya naturalizes easily there.) I will defer to local experts here on the ID.

Regards--
Ken.

I agree with Kenneth
Leaves of C. alata are much larger, and fruits somewhat spreading and not nodding, and more importantly thicker and distinctly winged (alata=winged) pods: Pl. see the link
