Friday Fabulous Flower -Rue those anemones

Today's FFF is a great little plant (and here too), but really wish the taxonomists would leave the names alone, of course TPP can never remember if this was the rue anemone or the false rue anemone.  Sounds like which ever came first claimed dibs.  This particular variety 'Shoaf's double pink' hardly counts as a native, but it's terribly cute. In this case it means developmentally stamen primordia have switched to producing petal-like flower parts, so the flower has that "rose" look to it, rather than having a single perianth surrounding multiple stamens and pistils. And then both the foliage and perianth have a nice pink tint to add to the cuteness. 
When first teaching about spring flowers way back in the early 70s, this plant was Anemonella thalictroides, but this species has now been submerged into the genus Thalictrum, so it becomes Thalictrum thalictroides.  Thalictrum was the genus of meadow rues, and it would help if someone knew what rues were.  These are members of the buttercup family, not the Rutaceae, the rue family. So no help. Although now TPP bitterly regrets bringing this up. Soon you will get to see another rue anemone whose name has been changed too.
