Last week, had an excursion to Dangar Fall of Oxley Wild River National Park. It was not surprised that water falls were spectacular. 
But the most exciting things were wild flowers. I haven’t seen them before. I don’t know their names, just took a few shot, hope some will name them.
Flower 1 (following comment by Eleanor Handreck
ehandreck@ozemail.com.au, I found this http://commons.wikimedia.org/wiki/File:Ranunculus_lanuginosus_Villaleinikki_H6187_C.jpg)
Flower 2 （Fringe Lilly)
Flower 3 (from comment of Andrew Hatcher hatchera@tpg.com.au) it’s Hyacinth Orchid (Dipodium punctatum). Impossible to grow in cultivation because of its saprophytic nature.
Flower 4
I know this is a kind of mushroom (nor sure how toxic it is)
Flowers on top right are Hyacinth Orchid (Dipodium punctatum). Impossible to grow in cultivation because of its saprophytic nature.
thanks Andrew Hatcher, after googled “Hyacinth Orchid” I found this web site

and found name for Fringe lilly too.
I think that picture 1 is a Ranunculus species. sorry I can’t tell you anything more. I’d like to know the ID of flower 4.
