how do you tell apart Northern and Southern Catalpa, really?

OK, I confess.

They're often derided, but I like Catalpas. Always have.

However, with the exteptions of the golden and purple leaved cultivars, I have a LOT of trouble telling apart the two native Catalpas...C. bignonioides & C. speciosa.

The only thing I can go off of is *usually* C. speciosa grows larger.

Are there any good "clues" to tell the difference?
