Unknown Flower

I was in the Volunteer Park Conservatory and took this photo of a beautiful flowering tree. Does anyone know what it is called? I am off to vacation and don't have time to go back and check it out... I think it is eye catching.

those flowers were pretty common in Malaysia. In Chinese, we called them "富贵花"。
