Strange flower. Like a cheese doodle.

And does it actually feel like sandpaper?

[DaveO]

Yes, the leaves and branches are stiff and rough.

[Andrea B.]

Australia has such an amazing array of interesting flowers. And seems to have quite a lot of "fluffy" flowers.

 

It is time for me to update the Australian List I once made for the reference section.

Andrea,

 

This may surprise you, here in Oz herbaria are a state (eg. Victoria, NSW) concern so in fact a plant may be known by different names in different states:

Council of Heads of Australasian Herbaria (CHCH)

Before you rush off to update your list, check if the "Splitters" and "Lumpers" have been busy.
