Flower With Long White Petals Anyone Know Of This Fragrant White Flower?

Anyone know of this fragrant white flower? - flower with long white petals

I recently Moody Gardens in Galveston Tx went and found a tree with fragrant flowers (I think). The flowers are long ourtward with 5 petals curved like a banana skin white. Landward of the flower was a yellow light. The leaves were a foot long and 5 cm wide. If anyone knows what it is, please let me know. I always have no luck with the Internet. Every little bit helps. Thanks
