Snowflake Aralia - Trevesia palmata

I came across this rare tree in the "Paseo del Parque" gardens in downtown Malaga. It took me quite a while to identify this tree as there are very images of it on the internet.
I went back to this tree several times to get pictures of its flowers at different stages of development. The flowers hang on the underside of this small trees rather large leaves (about 40cm in diameter). The flowers form balls of small yellow and white blossoms. The ball shape is about 10cm in diameter.
The Trevesia palmata is native to South China and grows in tropical or sub-tropical climates. The trees that I found were only about 3 meters tall.
The leaves have long stems (about 75cm long) and grow of the main truck which is covered with small thorns that slowly wear off.

The image below is of the flowers and leaves after they have dried out but are still hanging on the underside of the tree.
