Hi Evan,
The trouble is we have two entries of the same plant. The Catalogue of Life uses ITIS as it's reference source, and ITIS has listed a 2011 source.
Ranunculaceae of North America Update, database (version 2011) Acquired: 2011
Notes: Updated for ITIS by the Flora of North America Expertise Network, in connection with an update for USDA PLANTS (2007-2010)
The Flora of North America have it as Anemone americana but the date is only 1958, I would have thought there was an earlier naming of the plant unless it was split from another species at that date.

Funny thing is they link to TROPICOS where the accepted name of Anemone americana is Hepatica nobilis var. obtusa.

ITIS is out on a limb on it's own, Wiki states that some botanists include Hepatica in Anemone, maybe ITIS is run by such a botanist.

USDA plants has it still as Hepatica nobilis var. obtusa but most sites don't update, often because there's no agreement between sources but it does state in connection "with an update for USDA PLANTS (2007-2010)" on ITIS!

I found a Hepatica site but that is dated September 2010 ..

I'm afraid waiting to see what happens often doesn't happen, not for 10 years or more if ever!
