Unknown Tree

The attached tree (moderate size) grows in the Australian bed at RBG Melbourne. Any ideas much appreciated.

 

They have no planting records or maps?

 

There's planting records and maps, but I've been through the list for that grid, the surrounding grids, and most of the whole Australian bed - no luck with matching.

 

This looks rather like Polyscias sambucifolia subsp. sambucifolia

 

Tony - thanks - another Polyscias. Found the species 2 other places, and matches upper and under sides of leaves. Thank you.
