* = There has been some concern expressed about the milky sap that oozes from broken leaves and twiglets of the various Ficus species. The sap may be an eye/skin irritant to the animal that brushes up against it and gets it in their eyes (as may happen by accident in passing or when rubbing the eyelid against it as it gets ready to shed).
just found this information but this was published in 2007 and i have realised that not all previous information is still relevent for today
