It is not a native american plant, so if your book only covers the native ones it wouldn't be described.
Given the right conditions it is invasive. Some people - me - are very sensitive to the leaves of some Ranunculaceae, so if it spreads in the lawn (a wet lawn) and I laid down there in summer, months after flowering and with no apparent signs of this little cutie any more, I would be covered inmediately with raspberry red, fine dots everywhere! Once established it is very difficult to erradicate.
But I loved the flowers!
