What is the difference between Tecoma stans and Tecoma sambucifolia?

I thought all 3 of these trees were Tecoma stans but there appears to be a slight difference so could one or two of them be another species?

 

T. sambucifolia has much more pinnate-seeming leaves, more like Sambucus proper; looking at your three photos they're all T. stans for me. There's quite a bit of variation within the species.

 

Ok, thanks.
