Exciting for those not living in southern Australia, and perhaps for some who are. The flying duck orchid (Caleana major) seen in Willow Vale, near to my new home town. And in case you find all plants dull, I've included a local bird: a gang gang...

I think that's the best approach. While it seems an unlikely world distribution there is no definitive evidence it is a weed in Australia. It might be, or maybe not. More in the book, but that's the punchline!
