Plant in a protea bouquet

I posted a thread on the plant id forum to try and find out what kind of plant is in a protea bouquet I bought. Someone there suggested it might be an Australian plant, so I'm asking here if anyone knows what it is.

Thanks, Sue

Here's the bouquet.

And here's a detail of the white flowered plant I'm curious about.

Crikey! I don't know what it is, but what a beauty! Let us know if you get it ID'd somewhere else!

Here you go Sue it has been ID'd
