I find that GRIN is more comprehensive than ITIS. It still lists Pulsatilla georgica and P. turczaninovii as accepted species names (as of 2007-2008), but it posts the same comment for each:
"Comment: belongs in Anemone, but combination not yet made"
It says nothing about Pulsatilla campanella.

I tried to provide the link to all of the Pulsatilla entries, but it just went back to the general page. Just enter Pulsatilla in the search box on the general queries page.
