The idea is you look through the cutout area and lin it up with the wooden cutout of a leaf (in this image positioned immediately above the cutout). This lines up with the Lillypilly behind it.
It's a nice idea, interactive which the kids will enjoy, but I'd just prefer a simple label at the base of the tree saying "Lillypilly" and it's botanical name.
