Stephen, going by the leaf shape and flower I would say,
"Bauhinia variegata Candida"
Semi evergreen shrub grown for its flowers. Grown in a pot you can thin it out after flowering, water well in summer but reduce watering in winter.
Planted as a tree it will grow to 30 feet high and 30 feet spread, I will let you turn those measurements into Latin, I am too old for fiddling with what I grew up with.
Unless you have plenty of room keep it in the container, wheel it out when in flower then move something else in flower to the front, it works for me.
Frank.
