I modified “the leaves” by adding random for “leaves on the leaves” (Seriously, if someone know those names, please shoot ;)) and by reducing the number of them on each leave.
What I called dandelion “leave” seems to be named “diaspore”.
It’s the seed (called achene) + tissues that assist dispersal.
The name for the “leaves on the leaves” or the tissues assisting dispersal is “pappus”…
I may call that the “wings” or the “tissues” (it will be easier)
Thank you Wikipedia, I know a bit more about the World.
I hope I’m right, english is not my mother tongue and botany is not my science specialization.
