Friday Fabulous Flower at the fruit stage

Found this fruit in our woodland garden the other day, and it is a bit unusual.  Everyone's first thought is raspberry, and this is the same type of fruit derived from many pistils in the same flower, an aggregate fruit. 
So technically each unit is a fruitlet partially fused to its neighbors.  But this type of fleshy fruit is not common in this family (buttercup).  The leaf may not even help you identify this plant as it is not common here abouts, and it gets collected destructively for use as a medicinal and in many areas it is over collected.  This is Hydrastis canadensis, goldenseal.  How did you do?  Ever see this before?  The flower is constructed along the lines of last week's FFF, no showy perianth but lots of showy anthers around a number of pistils.
