Can someone provide me with the family this tree belongs to? I have tried several tree ID keys, without success. It is located in Inglewood, California on a hospital campus planted next to Melia azedarach, Ligustrum sinense, and Syzygium australe in bare soil surrounded by a lawn.
The leaves are palmately compound with either 3, 4 or 5 leaflets. Margins are entire, green on both sides, smooth (not hairy), buds are above heart-shaped leaf scars. I didn't see any glands on the leaves.
