It looks like a Golden Rain Tree.
DaisyI said:I suggested Golden RAIN tree (Koelreuteria paniculata)
Is this a shoot with several leaves attached?
Or is it a single compound leaf?
Have a look at Chinaberry.
I'm having difficulty matching your pics to my golden chain trees.
DaisyI said:Stone, Gymnocladus has the right leaf arrangement but has a smooth leaf edge. Koelreuteria paniculata has the leaf arrangement but with a toothy edge. Mike's tree has a very toothy edge.
Mike, there are Raintrees in California. Calflora is the best reference for California plants. Haven't you ever noticed that the world stops at the California state line? No one outside the state acknowledges CA and no one in CA acknowledges the rest of the country. (Native Californian speaking so nobody take offense).
