Here is some information about a common tree found here in Queensland, the African Tulip Tree - it's in flower now so you can spot them easily. Just click on the image above to enlarge it.

Seems they are deadly to our native stingless bees. If you have one of these - please get rid of it - it doesn't belong here and our bees are more important than it is.
