Goto next slide#10: Thistledown

The Definition:

thistledown : the typically plumose pappus from the ripe flower head of a thistle

Editor's Note:

"Alliterative, scientific & sexy, precise yet inducing wonder in the (natural) process. Obviously the words plumose and pappus will also need to be looked up by most people, but those are the right words to use here."
