Plant identification

Dougy2

Hi

I wonder if anyone can identify my mother's plant.  Note the thorns. It is probably one foot tall.

 Many thanks for you assistance.

I reckon that will be a tree.

But I don't know which one

Thanks 2 wheel.   

Looks like it is definitely a Erythrina, and most likely crista-galli.
